What Is An Interior Plain

Interior- Best 1 Definitions of Interior-plains

  • Except for a few minor spots where irrigation has recovered land, the whole region is a large desert, albeit only a few of the inner plains are referred to as “deserts” in local parlance. In addition to the ranges listed above, the Appalachian belt includes the plateaus sloping southward to the Atlantic Ocean in New England and south-eastward to the border of the coastal plain through the central and southern Atlantic states
  • And on the north-west, the Allegheny and Cumberland plateaus sloping southward to the Great Lakes and the interior plains
  • And on the east, the Appalachian plateaus sloping southward to the border of the coastal plain through Due to the stromy westerly winds, much of the rainfall is deposited on the western slopes of mountain ranges near the Pacific coast, and hence dry or desert interior plains can be found close to the ocean. In addition, there is the Arctic Slope area, which is a sloping plain similar to the interior plains of the United States, which lies between the Rocky Mountains and the Arctic Ocean. While the grass of the inner plains has a coarse texture and a yellowish color, it is significantly different in appearance from the grasses of the English meadows.

Interior Plains Facts for Kids

The Interior Plains are denoted with a bright red outline. In North America, the Interior Plains are a vast physiographic region that stretches across the Laurentian craton of centralNorth America, extending from the Gulf Coast region to theArctic Ocean along the east flank of the Rocky Mountains. The Interior Plains are home to a diverse range of plant and animal life. In Canada, it divides the Rocky Mountains from the Canadian Shield, whereas in the United States, it includes theGreat Plainsof the west and the Tallgrass prairieregion to the south of the Great Lakesextending east to theAppalachian Plateauregion.

Geologic history

It was a succession of tectonic plate collisions in the crust that shaped the heart of North America’s continent that provided the foundation for the modern-day interior plains of the United States and Canada. Mountain development and erosion surrounding the plains, as well as floods from inland seas, contributed the sediments that formed the rock strata that make up the inner plains’ rock strata.

Proterozoic Period (2500 to 542 MYA)

The Trans-Hudson Orogeny, which occurred between 2.0 and 1.8 billion years ago, joined the Hearne-Rae, Superior, and Wyoming cratons to form the North American craton, Laurentia, in an event known as the Trans-Hudson Orogeny (THO). This event was analogous to the Indian plate colliding with the Eurasian plate, which resulted in the formation of the Himalayas. Mount Everest was built after first collisions occurred during the THO, which was triggered by tectonic activity at the margins of the four major cratons.

The Black Hills of South Dakota are home to the last surviving outcrops of this orogeny in the central plains of the United States.

As a result, most of the Black Hills sedimentary record has been metamorphosed and distorted, making it difficult to determine the circumstances that existed at the time of their creation.

Paleozoic Era (542 to 251 MYA)

The Cambrian boom and the Permian extinction occurred during this time period, which is significant in Earth’s history. When global sea level rose and continents became partially buried, the waters experienced an explosion of sophisticated life, which was the first time such an event had occurred on the planet in recorded history. While the heart of Laurentia remained above sea level, when the continent drifted eastward towards other supercontinents such as Gondwana, the Appalachian Mountains began to develop some 400 million years ago, while the continent was still above sea level.

Deposition of eroded material from these mountains occurred on the Laurentian plains in the center part of the continent.

It is presently impossible to investigate sediments produced in the inner plains during this time period because they are buried deep beneath the surface and difficult to reach.

Mesozoic Era (251 to 65.5 MYA)

Around 220 million years ago, the supercontinent Pangea began to disintegrate, and the North American continent began to drift westward, eventually isolating itself. For a significant portion of this time period, the interior plains were submerged by inland seas. While the Jurassic period was in progress, the Sundance Sea formed along the western coast of the North American continent, extending from northern Canada to the interior plains, encompassing portions of the states of Wyoming, Montana, North Dakota, and South Dakota.

Another interior sea, known as theWestern Interior Seaway, was developed during theCretaceous era of Earth’s history.

The presence of limestone-shale couplets and carbonate layers in sedimentary deposits from this inland sea is common.

Cenozoic Era (65.5 MYA to Present Day)

This event occurred during the Laramide Orogeny, when the western Cordilleras were created as a result of the flat-slab subduction of the Farallon Plate beneath the North American Plate. This resulted in the formation of the frontal range of the Rockies, which runs from Montana to New Mexico. The outcrops that can be observed on the surface of the Rockies are composed of sandstone, granite, and limestone, as well as metamorphic rocks that were uplifted from the ProterozoicPeacetime period. This time has seen the inner plains stay relatively flat, with recent sedimentation resulting from erosion of the newly created Rocky Mountains as well as continuing erosion from Appalachia.

Glacial history

The Laurentide Ice Sheet began to spread southwards 2.6 million years ago, at the beginning of the Pleistocene Epoch, and eventually covered most of North America, from the northern Great Plains on the western side of the Interior Plains to the northern Great Plains on the eastern side of the Interior Plains and down into most of Minnesota and Wisconsin. Towards the end of the Pleistocene, the Laurentide Ice Sheet had a significant impact on the morphology of the Interior Plains, particularly the prairies.

  • When the plate melted, the pockets inside it were filled, leading in the formation of the kettle lakes.
  • A glacial paleolake named McConnell in northern Canada was gouged and filled by the Laurentide glacier during the glacial retreat.
  • The basin of Great Slave Lake was formed beneath the 4-kilometer-thick Keewatin Dome, and it is now the deepest lake in North America, according to the International Hydrographic Organization.
  • For example, Minnesota is commonly referred to as “the Land of 10,000 Lakes” because of the large number of lakes in the state and the significant recreational use that they get.

As a result of glaciation, meltwater coming from alpine glaciers in the Rocky Mountains carried sand and silt, resulting in the formation of alluvial deposits at their bases. Strong winds then carried this alluvium across the Interior Plains, distributing it throughout the region.

Sediment transport

Aeolian and fluvial processes are the primary means by which sediment is transported over the Interior Plains. The average temperature of the Interior Plains is rising as a result of climate change, and the region is becoming more drier as a result of the shift. Rain-driven erosion will become a more significant component in soil erosion in the Interior Plains as a result of the rise in the intensity of rainstorms.

Fluvial processes

The fluvial geomorphology of the Interior Plains has been changed as a result of civil engineering initiatives. River-blocking constructions such as dams and flow-regulators, which prevent normal sediment movement through river and channel systems, are in place. In the years before to 1900, it was believed that the Mississippi River transported 400 million tons of silt each year to the Gulf of Mexico. However, since the early twentieth century, engineering projects such as the construction of dams on the Missouri River, the creation of meander cutoffs, the training of rivers, the construction of bank revetments, and the implementation of soil erosion control measures have reduced the annual transport rate to between 100 and 150 million tons of sediment.

When suspended silt is trapped in the manmade structures, it cannot migrate downstream as it would in a naturally occurring river system.

Current land use

The Interior Plains of the United States are dominated by grassland and shrubland, which account for 44.4 percent of the total area. The western edge is primarily composed of shortgrass prairie, with blue grama and buffalograss as the dominant species. Prairies on the eastern side of the Interior Plains are dominated by tall grasses species such as big bluestem and switchgrass, which grow in abundance. It is separated from the other by a mixed-grass prairie, which comprises a variety of short and tall grasses, as well as the plants small bluestem and western wheatgrass.

Interior Lowlands

HomeGeographyTravel Northern America’s Physical Geography of the Land Region Alternative titles include: Plains of the Interior Located in the interior region of the North American continent, the Interior Lowlands are wide, mostly flat expanses of terrain. The word is frequently used in regional geology and physiographic descriptions of North America and the conterminous United States of America. From a tectonic standpoint, the continental Interior Lowlands are places that have been mostly unaffected by mountain formation throughout geologic time.

They are bounded on the west by the Great Plains, on the north and east by the Canadian Shield, and on the east by the Appalachian Mountains.

The Superior Upland, the Appalachian Plateau (but not the Appalachian Mountains), the Interior Low Plateaus, and the Ozark Plateau are all examples of uplands that are connected to them.

The Interior Lowlands of the United States, as well as its upland fringes Andrew Jackson is said to have said that the United States begins at the Alleghenies, meaning that only west of the mountains did the country come into being.

What are the differences between interior plains basins and plateaus?

Plains and plateaus have considerable variances in terms of topography. While a plain may not have any steep slopes, it does have a low height in comparison to its surroundings. Internal, or continental plains, are those that occur in the interiors of continents; coastal plains, on the other hand, are those that occur around the shores of continents.

Is there a difference between interior and coastal?

A coastal plain is a flat, low-lying area of ground adjacent to the ocean that is flat and low-lying.

Landforms such as mountains, which separate coastal lowlands from the remainder of the interior, serve to separate them. When the ocean level drops, the land becomes exposed, resulting in the formation of a coastal plain. These coastal lowlands can sometimes be seen extending further inland.

What is the meaning of the geographical term landform?

What is a common difference between coastal areas of land and inland areas?

Because water has a larger heat capacity than soil and rock, it takes far longer for the ocean to heat up and cool down than it does on land. Because of the heat capacity of the water, coastal locations will often have more mild temperatures than inland places in the summer. Prepare equipment trays for each set of people.

What are 3 main differences between coastal and inland climates?

Climate Variations Between the Coastal and Inland Environments For example, the temperature fluctuation in maritime climates is 10-15 degrees Celsius, but the temperature variance in inland climates can be as high as 40 degrees Celsius. On the one hand, coastal climates have wetter winters and dryer summers; on the other, inland climates have hot, humid summers and cold, dry winters.

Why does a coastal area have less variation in temperature than a non coastal area?

A coastal location has less temperature variance than a non-coastal area because the cooling and heating of water is less in contrast to the cooling and heating of land.

What do we use to compare places and landforms?

To explain, a landform map is a map that illustrates the positions of landforms in a given area of land. Mountains, hills, plateaus, plains, and other features are frequently depicted in color on these maps. They also illustrate the locations of large bodies of water.

What do plains look like?

What is landscape geography?

A landscape is a portion of the Earth’s surface that may be seen at a single moment from a single point on the planet. It is made up of the geographical elements that distinguish or characterize a certain location. Some geographers, such as Otto Schluter, consider geography to be a branch of landscape science rather than a separate discipline.

What is the difference between Rocky Mountains and the Great Plains?

Students discover that the rock of the Great Plains is sedimentary rock, whereas the rock of the Rocky Mountains is volcanic rock (see image). Because they formed in separate ways, it is unlikely that they formed together.

How do the Rocky Mountains differ from the Intermountain region?

Topic – The Interior Plains

Canada’s Geographical Map


In North America, the Interior Plains area stretches from Alaska to the Arctic Ocean and is located on the east side of the Cordillera mountain range.

A considerable portion of Alberta, Saskatchewan, and Manitoba, as well as a portion of the Northwest Territories, are included in the region as well.

Physical Features

The Interior Plains region has a field. The Interior Plains region is characterized by its flat terrain and undulating hills. In the foothills of the Rocky Mountains, the elevation of the land is at its highest point. In Manitoba and the Northwest Territories, the land is nearly completely submerged beneath the surface of the water. Glaciers blanketed the Interior Plains and most of Canada thousands of years ago, and they continue to do so now. Because of the weight of the glaciers, the terrain became flat with undulating hills as a result of the compression generated by the glaciers.

Lakes and rivers were produced as a result of the melting of the glaciers.

a field of wheat The southern portion of the Interior Plains has the greatest amount of cropland in all of North America.


The Interior Plains have chilly winters and scorching summers across the majority of their territory. The region receives the least amount of precipitation in all of Canada, and droughts can occur in various parts of the country. When there is no rain or snow for an extended length of time, a drought is declared. Because of the drought in the southern Interior Plains, the grasses go into dormancy and do not begin to grow again until the weather improves. Irrigation, often known as soil watering, is occasionally required for crop production.


Species of trees and plants found on the Interior Plains A variety of trees and plants may be seen growing beside streams and around bodies of water. The majority of trees are deciduous. The natural vegetation of the southern Interior Plains is primarily comprised of grasses. Small plants, mosses, and grasses are the only things that grow in the northern half of the Interior Plains.


Birds such as ducks, geese, and swans, wolves, and polar bears, herbivores such as deer, moose, elk, and caribou, and carnivores such as coyotes, eagles, and hawks, exist in the northern hemisphere.

Natural Resources

Minerals such as coal, coal ash, potash, oil, and gas agricultural land in the region’s southernmost portion.
