Plate Tectonics Practice

Front

What is a Transform Boundary?

Back

A type of tectonic boundary where two plates slide past each other, often causing earthquakes.

Front

What evidence supports the theory of continental drift?

Back

Matching fossils found across different continents.

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Asthenosphere.

Front

What is a Divergent Boundary?

Back

A boundary where two tectonic plates move away from each other, allowing magma to rise and create new crust.

Front

What is the significance of the superposition principle in geology?

Back

In a sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest are at the top.

Front

What is a Convergent Boundary?

Back

A boundary where two tectonic plates collide, often forming mountains or causing subduction.

Front

What is the Asthenosphere?

Back

A semi-fluid layer of the Earth's mantle that allows tectonic plates to move.

Front

What is subduction?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is the lithosphere?

Back

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