The change in shape of rock caused by stress.
What is Strain?
Stress resulting from squeezing.
What is Compression?
Curved line of volcanic islands that forms parallel to a plate boundary.
What is a Volcanic Arc?
An area that is extensive and mostly flat.
What is a plain?
This is why the growth of Earth's tectonic plates isn't noticeable.
What is slow growth and erosion?
Upward vertical motion of Earth's surface.
What is Uplift?
Stress that pulls something apart.
What is Tension?
Deep, underwater trough created by one plate subducting under another plate at a convergent plate boundary
What is an Ocean Trench?
An area of subsidence and low elevation.
What is a basin?
These deformations are produced by compression of plastic crust.
What are folds?
Downward vertical motion of Earth's surface
Stress resulting from parallel forces acting in opposite directions
What is Shear?
Made of layers of rocks that are folded
What is a folded mountain?
This is the reason land surface area is high where the crust is thick.
What is isostasy?
This type of deformation occurs in the lower crust.
What is plastic deformation?
Area where tectonic plates slide horizontally past each other.
What is a Transform Fault?
The stress that forms the largest mountains and mountain ranges.
What is compression?
Parallel ridges that form where blocks of crust move up at faults
What are Fault-block mountains?
These are the causes of rocks to be exposed at Earth's surface.
What are Erosion and Uplift?
The Appalachian mountains will most likely look like this in 200 million years, due to weathering and erosion.
What is flat or plains?
Equilibrium between continental crust and the denser mantle below it
What is isostasy?
The stress responsible for creating mid-ocean ridges.
What is Tension?
Forms when large regions rise vertically with very little deformation
What are Uplifted mountains?
This type of mountain forms with little deformation.
What is Uplifted mountains?
This would cause Earth's surface to become flatter, filled with less mountains and more basins and plains.
What is the tectonic plates stopping?
