UNIT 5 STUDY GUIDE REVIEW

Convection currents in the mantle cause tectonic plates to move.

Rock strata are layers of rock deposited at different times in Earth's history.

The principle of original horizontality states that sedimentary rocks are deposited in vertical layers.

Any tilting or bending of rock layers happens before they are deposited.

Stress applied to rocks from tectonic movement can lead to earthquakes.

The elastic limit is the maximum stress a rock can withstand before deforming.

Rocks are more likely to bend than break when they are at a high temperature.

Folds typically occur near the Earth's surface where it is cooler.

Faults are more common deep within the Earth where it is warmer.

The composition and temperature of rocks affect their elastic limit.
