Plate tectonics

Front

What are plate boundaries?

Back

Plate boundaries are the edges where two tectonic plates meet. They are classified into three main types: divergent, convergent, and transform boundaries.

Front

Where are earthquakes and volcanoes most likely found?

Back

Earthquakes and volcanoes are most likely found at plate boundaries.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once part of a single supercontinent.

Front

What was the name of the supercontinent proposed by Alfred Wegener?

Back

The supercontinent proposed by Alfred Wegener is called Pangaea.

Front

What happens at divergent boundaries?

Back

At divergent boundaries, tectonic plates move apart from each other, leading to the formation of new crust, often resulting in volcanic activity.

Front

What geological features are formed when two continental plates collide?

Back

When two continental plates collide, mountain ranges are formed.

Front

Who first proposed the theory of continental drift?

Back

The theory of continental drift was first proposed by Alfred Wegener.

Front

What are transform boundaries?

Back

Transform boundaries are places where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is the significance of the theory of plate tectonics?

Back

The theory of plate tectonics explains the movement of Earth's plates and accounts for many geological phenomena, including earthquakes, volcanic activity, and mountain building.

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates are moving apart, often characterized by steep walls and a central block.
