Test - Plate tectonics

Front

What are pillow-shaped rocks?

Back

Pillow-shaped rocks are formed by the rapid hardening of molten material, typically found at mid-ocean ridges.

Front

What forms when continental plates pull apart at a divergent boundary on land?

Back

A rift valley forms when continental plates pull apart at a divergent boundary on land.

Front

What is the geological theory that states pieces of Earth’s lithosphere are in constant, slow motion?

Back

Plate tectonics is the geological theory that states pieces of Earth’s lithosphere are in constant, slow motion.

Front

According to Wegener’s hypothesis of continental drift, what was the state of the continents?

Back

According to Wegener’s hypothesis, the continents were once joined together in a single landmass.

Front

What causes Earth’s magnetic field?

Back

Earth’s magnetic field results from movements in the outer core.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive, irregularly shaped slab of solid rock that makes up the Earth's lithosphere.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move toward each other, often causing one plate to be forced beneath the other.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.
