When were Interior Plains formed?
The Interior plains (land form formed when cratons collided and went together 1.9 billion years ago) were originally covered by shallow inland seas 500 million years ago. Sediments from the Rocky Mountains then were deposited as well as sediments from rivers flowing into the area over millions of years.
What is the environment in the Interior Plains?
"The Interior Plains has long, cold winters and short, hot summers." (The Interior Plains p. 8). Winters in the Interior Plains are able to go as low as -30°C, and summers that reach above 30°C (The Interior Plains p. 8).
What is the climate like in the Interior Plains?
The climate of the Interior Plains is very diverse. Weather is very extreme; up north, long winters and summers are short and cool, and down south, summers are long and hot and winters are cold, however there is very little precipitation.
Where are the Interior Plains in the United States?
The Interior Lowlands of the United States lie in a vast grassy expanse between the Appalachian Mountains and the Great Plains. Over a dozen states contain at least a part of this region, including Ohio, Indiana, Illinois, Kentucky, and Tennessee.
What are the physical features of the interior lowlands?
The Interior Lowlands are located west of the Appalachian Mountains and east of the Great Plains. The main geographic characteristics of this region include: rolling flat lands with many rivers, broad river valleys, and grassy hills.
When were the Interior Plains formed?
The Interior plains (land form formed when cratons collided and went together 1.9 billion years ago) were originally covered by shallow inland seas 500 million years ago. Sediments from the Rocky Mountains then were deposited as well as sediments from rivers flowing into the area over millions of years.
What are rocks?
Rocks are mineral aggregates with a combination of properties of all the mineral traces. Any unique combination of chemical composition, mineralogy...
What are the different types of rocks?
There are three types of rocks: Igneous Rocks Sedimentary Rocks Metamorphic Rocks
Which is the most common type of igneous rock?
Basalt is the most common type of igneous rock. The majority of the ocean floor is composed of basalt.
Give some examples of sedimentary rocks.
Some common sedimentary rocks are: Limestone Chalk Clay Sandstone Shale
How are sedimentary rocks formed?
Sedimentary rocks are formed by the deposition and subsequent cementation on the material at the Earth’s surface within the bodies of water. These...
What are the characteristics of rock?
Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types. Additionally, different classification systems exist for each major type of rock.
What are the two types of igneous rocks?
Types of Igneous Rock. Following are the two types of igneous rock: Intrusive igneous rock: These rocks crystallize below the earth’s surface resulting in large crystals as the cooling takes place slowly. Diorite, granite, pegmatite are examples of intrusive igneous rocks. Extrusive igneous rock: These rocks erupt onto the surface resulting in ...
What are the two types of metamorphic rocks?
Following are the two types of metamorphic rock: Foliated metamorphic rocks: These rocks are produced by the exposure to heat and pressure which makes them appear layered. Phyllite, gneiss are examples of foliated metamorphic rock s. Non-foliated metamorphic rocks: These rocks don’t have layers.
What are the three types of sedimentary rocks?
Types of Sedimentary Rock. Following are the three types of sedimentary rock: Clastic sedimentary rocks: These rocks are formed from the mechanical weathering debris. Sandstone, siltstone are examples of clastic sedimentary rocks. Chemical sedimentary rocks : These rocks are formed from the dissolved materials that precipitate from the solution.
What are some examples of extrusive igneous rocks?
The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.
How is igneous rock formed?
Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of existing rocks in either a planet’s mantle or crust.
How are metamorphic rocks formed?
They may be formed simply by being deep beneath the Earth’s surface, subjected to high temperatures and the great pressure of the rock layers above it. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form”.
Overview
Geologic history
A series of tectonic plate collisions in the crust that formed the center of the North American continent laid the groundwork for the modern-day interior plains. Mountain building and erosion around the plains as well as flooding from inland seas provided sediments that make up the rock strata of the interior plains.
Between 2.0 and 1.8 billion years ago the Hearne-Rae, Superior, and Wyoming cratons were sutu…
Glacial history
2.6 million years ago at the start of the Pleistocene Epoch, the Laurentide Ice Sheet began to spread southwards to cover North America down to the northern Great Plains on the western side of the Interior Plains and down into most of Minnesota and Wisconsin. The Laurentide Ice Sheet had a large influence on the morphology of the Interior Plains during the end of the Pleistocene. During retreat, the Laurentide scoured numerous pockets of sediment. Upon the plate’s melting, …
Sediment transport
Sediment transport within the Interior Plains occurs primarily by aeolian and fluvial processes. Due to climate change, the average temperature of the Interior Plains is increasing and the region is becoming more arid. Because of the increase in rainstorm intensity, rain-driven erosion will grow as a factor of soil erosion in the Interior Plains.
Current land use
Grassland and shrubland make up the largest portion of the Interior Plains within the United States, at 44.4 percent. The western margin is mainly shortgrass prairie dominated by blue grama and buffalograss. Prairies on the eastern side of the Interior Plains are dominated by tall grasses varieties including big bluestem and switchgrass. The two regions are separated by mixed-grass prairie, which contains both short and long grass varieties as well as little bluestem and western …
