Rock Cycle and Plate Tectonics Unit 5 Review

Front

What process drives plate tectonics?

Back

Convection currents in the mantle.

Front

How does plate tectonics explain the presence of plant fossils in areas where the plants cannot live?

Back

Plate tectonics caused the continents to drift, moving the locations of the fossils.

Front

What are the three major rock types?

Back

Igneous, Sedimentary, Metamorphic.

Front

Define igneous rocks.

Back

Igneous rocks are formed from solidified magma or lava.

Front

Define sedimentary rocks.

Back

Sedimentary rocks are formed from the accumulation of sediments.

Front

Define metamorphic rocks.

Back

Metamorphic rocks are formed from the transformation of existing rock types under heat and pressure.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering involves the alteration of the chemical composition of rocks.

Front

Give an example of physical weathering.

Back
