ES Unit 6 Plate Tectonics & Unit 7 Earth’s Changing Surface Test

Front

What is the primary energy source for the formation of a rift?

Back

Mantle convection.

Front

What evidence supports the predictability of Earth's tectonic plate motion?

Back

Continents are separating at a rate of 3–5 cm/year.

Front

What is a main source of energy for the cycle of rock flow within the mantle?

Back

Earth’s mantle, where radioactive elements decay.

Front

What effect could a strong volcanic eruption have on Earth's systems?

Back

Ash and sulfuric gas would block sunlight, lowering temperatures.

Front

How does climate affect the rate of weathering of rocks near the equator?

Back

High temperature and moisture result in a fast rate of weathering.

Front

What are tectonic plates?

Back

Large sections of Earth's lithosphere that move and interact with each other.

Front

What is the theory of plate tectonics?

Back

The theory that explains the movement of Earth's plates and the associated geological phenomena.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What is mantle convection?

Back

The slow movement of Earth's mantle caused by heat from the core, driving plate tectonics.

Front

What are seismic waves?

Back

Waves of energy that travel through the Earth, often caused by earthquakes.
