3. Geologic Processes

Erosion

Weathering

Deposition

Mass wasting

Erosion creates new rocks.

Weathering moves sediments.

Weathering breaks down rocks, erosion moves them.

Both are the same.

Volcanism is an internal process that builds landforms from inside the Earth. 

Volcanism only happens underwater.

Volcanism breaks down rocks on the surface.

Volcanism helps with the movement of weathered materials.

Solar radiation

Photosynthesis

Radioactive decay of elements

Ocean currents

Magma only forms underwater

Magma can also form at plate boundaries

Magma cannot form without human activity

Magma is not real

Plates are melting

Plates are pulling apart

Plates are sliding past each other

Plates are colliding

It generates wind currents

It pulls crust inward

It drives the movement of tectonic plates

It causes ocean tides

Folds break while faults bend

Folds occur in the mantle, faults in the crus

Folds bend rocks; faults break them

Folds are caused by earthquakes; faults are not

Because rocks are being pushed together and cause folding.

Because the land is stretched and pulled apart.

Because the Earth's crust is sliding in opposite directions.

Because rock layers are forced upward.

Compression – because it squeezes rocks together to form ridges

Tension – because it stretches the crust and pulls rock layers away from each other

Shearing – because it causes rocks to slide past one another 

Friction – because it prevents rocks from moving during stress
