Continental Drift and Plate Tectonics

The theory that continents have moved over geological time and were once joined together in a single landmass called Pangaea.

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

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

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

A tectonic plate boundary where two plates move apart, leading to the formation of new crust, such as at mid-ocean ridges.

The process by which new oceanic crust is created at mid-ocean ridges and moves away from the ridge.

A vent in the Earth's crust through which lava, ash, and gases are expelled.

The theory was developed by multiple scientists, but Alfred Wegener is known for the earlier theory of Continental Drift.

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

Earthquakes are caused by the sudden release of energy in the Earth's crust due to tectonic plate movements.
