The slow, never-ending process of rock changes
What is the rock cycle?
The movement of rock, soil and minerals from one place to another.
What is erosion?
Mountains are worn down over time by these two forces.
What are weathering and erosion?
Name the three major types of rocks
What are igneous, metamorphic and sedimentary rocks?
The deepest part of the Earth's oceans.
What are ocean trenches?
The breakdown of rock by physical and/or chemical forces
What is weathering?
A type of rock formed by layers of sediments that were squeezed and stuck together over a long period of time.
Since the continental crust is this than the Earth's mantle, the continents can rise above the seafloor.
What is less dense?
This type of rock is changed over time by pressure, heat and chemicals.
What is a metamorphic rock?
Even though plates move horizontally, it causes the crust to move this way.
What is vertically?
Squeezing stress.
What is compression?
Stress that pulls something apart.
What is tension?
Besides weathering and erosion, the factor that plays into mountains appearing different.
What is age?
This brings rocks to the surface.
What is uplift?
Explain the difference between converge and diverge.
Tectonic plates that slide horizontally past each other.
What is transform fault?
A curved line of volcanoes that forms parallel to a plate boundary.
What is volcanic arc?
Plate tectonics and erosion cause these to change over time.
What are continental plates?
This type of rock is found near water sources with fossils from decayers.
What is sedimentary rock?
When divergent boundaries occur within a continent, they form these.
What are continental rifts?
A change in the shape of rock caused by stress.
What is strain?
An area of many fractured pieces of crust along a large fault.
What is a fault zone?
These two things cause the Earth's surface to move up and down.
What is subsidence and uplift?
When a metamorphic rock subducts, it turns into this.
What is magma>?
Types of landforms created by these are less obvious than landforms created by tension and compression.
What is shear stress?
