Crust
The layer of rock underneath the soil.
bedrock

Uplift rate

Mantle
When wind, water, ice, or other things break down larger rocks into smaller pieces.
Weathering
Rock that forms when magma or lava cools and becomes hard.
Igneous Rock
Rock that has been changed by heat and pressure.
metamorphic rock

Deposition
The speed at which the land is being eroded away.
Erosion Rate
When smaller pieces of rock and soil are moved away because of water, wind, ice, etc.
Erosion
A plate boundary where two plates move away from each other.
divergent boundary
a crack in the Earth's surface between two pieces of bedrock.
faultline
Measure of the energy released during an earthquake.
magnitude
A plate boundary where two plates slide past each other.
Transform boundary
A plate boundary where two plates move toward each other.
convergent boundary
Rock made from sediment crushed together under high pressure and temperature
sedimentary rock
When hot bedrock deep underground moves, changes shape, and shifts.
creep
Hot, melted rock underneath the surface of the Earth.
