Tectonic Plates

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform.

Front

What is a divergent plate boundary?

Back

A boundary where two tectonic plates move apart from each other.

Front

What is a convergent plate boundary?

Back

A boundary where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What is a transform plate boundary?

Back

A boundary where two tectonic plates slide past one another horizontally.

Front

What is the process of convection in the Earth's mantle?

Back

The movement of warm, less dense material rising and cooler, denser material sinking, driving plate tectonics.

Front

What is uplift in geological terms?

Back

The process by which tectonic forces cause the Earth's crust to rise, often forming mountains.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener.

Front

What evidence supports the theory of continental drift?

Back

Fossil distribution, geological similarities, and the fit of continental coastlines.

Front

What is subduction?

Back

The process where one tectonic plate is forced under another, often leading to volcanic activity.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.
