Plate tectonics Review

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 is Pangaea?

Back

A supercontinent that existed during the late Paleozoic and early Mesozoic eras, which eventually broke apart due to plate tectonics.

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Earth's mantle, which are caused by the heat from the Earth's core.

Front

What is Sea-floor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What are plate boundaries?

Back

The edges where two tectonic plates meet, which can be divergent, convergent, or transform.

Front

What occurs at divergent boundaries?

Back

Tectonic plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What occurs at convergent boundaries?

Back

Tectonic plates move towards each other, which can result in subduction, mountain building, or volcanic activity.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

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

Front

What natural events are commonly associated with plate boundaries?

Back

Volcanoes and earthquakes.
