Amplify Plate Motion - Chapter 1, 2, 3 review

Front

What is the theory of continental drift?

Back

The theory of continental drift suggests that continents have moved over geological time from a common supercontinent, Pangaea, to their current locations.

Front

What evidence did Wegener use to support his theory of continental drift?

Back

Wegener used evidence such as the fit of the continents, fossil correlations, and geological similarities across continents to support his theory.

Front

What happens at divergent plate boundaries?

Back

At divergent plate boundaries, tectonic plates move away from each other, leading to the formation of new crust as magma rises and solidifies.

Front

What is the role of magma in plate tectonics?

Back

Magma plays a crucial role in plate tectonics by rising from the mantle to create new crust at divergent boundaries and causing volcanic activity.

Front

What occurs at convergent plate boundaries?

Back

At convergent plate boundaries, tectonic plates move towards each other, which can result in subduction, mountain building, or earthquakes.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.

Front

How do tectonic plates interact at transform boundaries?

Back

At transform boundaries, tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is the composition of Earth's outer layer?

Back

Earth's outer layer, also known as the lithosphere, is composed of hard, solid rock beneath the soil and water.

Front

What is the significance of plate tectonics in understanding Earth's geology?

Back

Plate tectonics is significant because it explains the movement of continents, the formation of mountains, earthquakes, and volcanic activity.

Front

How does the movement of tectonic plates affect the Earth's surface?

Back

The movement of tectonic plates shapes the Earth's surface by creating landforms such as mountains, valleys, and ocean basins.
