Amplify Plate Motion Test Review

Front

What is the Earth's outer layer made of underneath the soil and ocean?

Back

The Earth's outer layer is made of hard, solid rock underneath both the soil and the ocean.

Front

What happens when two tectonic plates move apart?

Back

Soft, solid rock from underneath the plates rises and hardens, adding solid rock to the edges of both plates.

Front

What does the presence of Lystrosaurus fossils in India and South Africa suggest about plate movement?

Back

India and South Africa are parts of different plates that slowly moved far apart over millions of years.

Front

True or False: Earthquakes are caused by plate motion.

Back

True

Front

What occurs when two tectonic plates move toward each other?

Back

One plate goes underneath the other plate and sinks into the soft rock below.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which is divided into tectonic plates.

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 the lithosphere?

Back

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

Front

What is the process of subduction?

Back

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

Front

What is the significance of GPS in studying plate motion?

Back

GPS is used to track the movement of tectonic plates and measure their speed and direction.
