Plate Tectonics

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 that float on the semi-fluid asthenosphere.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What occurs at a divergent boundary?

Back

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

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates collide, often resulting in mountains, earthquakes, or volcanic activity.

Front

What is a transform boundary?

Back

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

Front

What geologic feature is commonly found at a convergent boundary between continental crusts?

Back

Mountains.

Front

What is convection current?

Back

The cycle of movement in fluids caused by the uneven heating of the fluid, which drives ocean currents, weather patterns, and tectonic plate movements.

Front

Why can convection occur in the asthenosphere?

Back

Because the asthenosphere is a material that can flow.

Front

What geologic event is most likely to occur at a transform boundary?

Back

Earthquakes.

Front

What is the lithosphere?

Back

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