Plate Tectonics

Front

What is Plate Tectonics?

Back

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

Front

What is Sea Floor Spreading?

Back

The process that adds new crust to the ocean floor along mid-ocean ridges, causing the ocean floor to expand.

Front

What are Plate Boundaries?

Back

The edges where two tectonic plates meet, which can lead to earthquakes, volcanic activity, and mountain building.

Front

What is Pangea?

Back

A supercontinent that existed millions of years ago, where all continents were joined together.

Front

What are Faults?

Back

Breaks in Earth's crust where rocks have slipped past each other, often causing earthquakes.

Front

What is Continental Drift?

Back

The theory that continents have moved over geological time from a single landmass to their current locations.

Front

What is Subduction?

Back

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

Front

What are Earthquake Epicenters?

Back

The point on the Earth's surface directly above where an earthquake originates.

Front

What is a Rift Zone?

Back

An area where tectonic plates are moving apart, often leading to the formation of new crust.

Front

What are Hot Spots?

Back

Volcanically active areas that are not located at plate boundaries, often resulting in island chains.
