Forces that shape the earth
These processes break down and remove parts of mountains.
What are weathering and erosion?
These are the forces that cause rocks to change shape
What are shear, tension, and compression stresses?
These are a special type of mountain as they form from volcanic eruptions
What are volcanoes?
Typically the highest elevations are found near this part of a continent
This is the process of rocks changing from one type of rock to another type of rock
What is the rock cycle
This process brings rocks from deep within the Earth closer to Earth's surface
What is uplift
These are underwater troughs created by one plate subducting under another plate
What are ocean trenches?
As erosion removes the upper part of the crust of fold mountains these formations become visible.
What are folds?
These types of rocks make up the vast majority of continental interiors
What are metamorphic and igneous rocks?
This is a force acting on a surface
What is stress?
This process takes all types of rocks deep within the Earth where they are exposed to an increase of pressure and temperature
What is subduction?
This is where the hot mantle rises and pushes the seafloor upward, making a long tall ridge
What is a Mid-Ocean Ridge?
This type of mountain is made up of rocks that have very little deformation
What are uplift mountains?
What are basins?
These are created by tension stresses in the cold upper part of the crust
What are faults?
This is the downward vertical motion of Earth's surface
This type of stress occurs when plates move apart and the Earth's crust is stretched.
What is tension stresses?
This is the term used to describe a volcano that is not currently erupting but may erupt again in the future
What is dormant
What is the Colorado plateau?
This creates a permanent change in a rock’s shape and affects hot or weak rocks
What is plastic strain?
Isostasy is the balance or ___________ between the continental crust and the mantle
What is equilibrium?
This landform is happens at a divergent plate boundary and eventually leads to a continent splitting into 2 parts
What is a rift valley?
This mountain's name means other side of the river
What are the Appalachian Mountains?
Uplifting and _____________ are the two ways that plateaus can form
What are volcanic eruptions?
When this process happens a mountain looses mass, in response the root under mountains must rise restore the balance between what is left of the mountain and how it floats on the mantle.
What is erosion?
