Which landform dominates the United States?
Most of the area of the United States is taken up by plains.
What is the difference between fault-block and upwarped mountains?
Fault-block mountains are formed by vertical movement along a fault. The rock along one side of the fault is thrust upward, while the rock on the other side of the fault drops down. Upwarped mountains are formed by broad uplift of blocks of rocks in the Earth’s crust.
Explain the differences between the following: Plains, Plateaus and Mountains. Be sure to include the different types of each landform in your answer.
Plains include interior and coastal. These landforms are flat and found either by the coast or in the middle of a continent. Plateaus are flat, raised areas caused by uplift of the land. Mountains include folded, volcanic, fault block and unwarped. They are formed when the land is pushed upward by forces inside the Earth.

How are folded mountains formed?
Folded mountains are formed when forces inside the Earth squeeze layers of horizontal rock. The layers of rock fold and buckle upwards just like a rug pushed together might.
What are some features that might allow you to identify upwarped mountains?
Upwarped mountains typically have high peaks with sharp ridges.
Compare and contrast plains and plateaus.
Both are landforms that are flat. However, plateaus rise steeply from the land around them.
Describe how volcanic mountains are formed.
Volcanic mountains are formed as molten rock reaches the surface of Earth through weak areas in the crust. The material is deposited and piles up, forming a cone shaped mountain.
How do coastal and interior plains differ? How are they similar?
All plains are areas of nearly flat land with low relief. Coastal plains have low elevation in addition to low relief. In contrast, while interior plains always have low relief, they may vary greatly in elevation.
