What is the Earth's outer layer made of?

Back

The Earth's outer layer is made of hard, solid rock.

Front

What is plate motion?

Back

Plate motion refers to the movement of the Earth's tectonic plates, which can cause earthquakes, volcanic activity, and the formation of mountains.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the Earth's mantle, not directly from earthquakes.

Front

What is a metamorphic rock?

Back

A metamorphic rock is a type of rock that has been changed from its original form due to intense heat and pressure.

Front

How can a metamorphic rock change into a sedimentary rock?

Back

A metamorphic rock can change into a sedimentary rock by being broken down into smaller pieces, transported, and compacted into layers.

Front

What is the significance of fossils in understanding plate tectonics?

Back

Fossils, like those of Lystrosaurus, provide evidence of how continents have moved apart over time, indicating that they were once connected.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move toward each other, which can result in one plate being forced beneath the other.

Front

What is the role of GPS in studying plate motion?

Back

GPS is used to track the movement of tectonic plates in real-time, helping scientists understand how fast and in what direction they are moving.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
