Plate Tectonics

Front

What causes plate movement?

Back

Plate movement is caused by convection currents in the mantle.

Front

What landform is typically found at a convergent boundary between two continental crusts?

Back

Mountain.

Front

What type of plate boundary created the Great Rift Valley and the Mid-Atlantic Ridge?

Back

Divergent.

Front

Why did most geologists reject Alfred Wegener's idea of continental drift?

Back

Wegener could not identify the force that moved the continents.

Front

What landform is typically found at a convergent boundary between two oceanic crusts?

Back

Ocean Trench.

Front

Define '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 divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to the formation of mountains, trenches, or volcanic activity.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is the lithosphere?

Back

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