Amplify Plate Motion

Front

What is plate motion?

Back

The movement of the Earth's lithospheric plates on the semi-fluid asthenosphere beneath them.

Front

How long does it take for tectonic plates to travel great distances?

Back

Millions of years.

Front

What are the three main types of plate boundaries?

Back

Convergent, Divergent, and Transform boundaries.

Front

What happens at a divergent plate boundary?

Back

Plates move apart, creating new crust as magma rises to the surface.

Front

What geological features are often associated with convergent plate boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

What is the significance of the Mesosaurus fossils found on different continents?

Back

They provide evidence for continental drift, suggesting that continents were once connected.

Front

What is a transform fault?

Back

A type of boundary where two plates slide past each other horizontally.

Front

What role do earthquakes play in understanding plate motion?

Back

They indicate the movement and interaction of tectonic plates.

Front

What is the Earth's outer layer called?

Back

The lithosphere, which is divided into tectonic plates.

Front

What is subduction?

Back

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