6th (6.10D - Plate Tectonics/Geological Events) Part 1

Front

What is plate tectonics?

Back

The theory that explains the structure and movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What happens at a convergent plate boundary?

Back

Two tectonic plates push toward each other, which can lead to the formation of mountains or subduction.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move away from each other, often creating new crust.

Front

What is subduction?

Back

The process where one tectonic plate slips under another at a convergent boundary.

Front

What geological feature is commonly formed at divergent boundaries?

Back

Mid-ocean ridges, where new oceanic crust is created.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other horizontally.

Front

What can happen when tectonic plates move?

Back

They can cause earthquakes, volcanic eruptions, and the formation of mountains.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates, often found on land.
