APES 4.1 - Plate Tectonics

Front

What is a Transform Plate Boundary?

Back

A type of plate boundary where two tectonic plates slide past one another, causing earthquakes.

Front

What landform is created when two oceanic plates collide?

Back

Volcanoes are formed when two oceanic plates collide, leading to subduction and magma formation.

Front

What are tectonic plates?

Back

Chunks of the lithosphere that move and interact at plate boundaries, causing geological activity.

Front

What is Subduction?

Back

The process where one tectonic plate is pulled beneath another, typically occurring at convergent boundaries.

Front

What is the Lithosphere?

Back

The thin layer of rock that forms the Earth's surface, consisting of the crust and the uppermost mantle.

Front

What is a Divergent Plate Boundary?

Back

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

Front

What are Mid-Oceanic Ridges?

Back

Underwater mountain ranges formed by the upwelling of magma at divergent plate boundaries.

Front

What is Seafloor Spreading?

Back

The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates move apart.

Front

What is a Convergent Plate Boundary?

Back

A type of plate boundary where two tectonic plates collide, leading to subduction or mountain formation.

Front

What is the Asthenosphere?

Back

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