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 layers of the Earth?

Back

The inner core, outer core, mantle, and crust.

Front

How does temperature change as you move from the crust to the inner core?

Back

Temperature increases as you move deeper into the Earth.

Front

What is Pangaea?

Back

An ancient supercontinent that existed about 280 million years ago, where all continents were joined together.

Front

What are convection currents?

Back

Movements within the mantle caused by the heat from the Earth's core, driving the movement of tectonic plates.

Front

What geological feature is formed at mid-oceanic ridges?

Back

New oceanic crust is formed as tectonic plates diverge.

Front

What occurs at a convergent boundary between two continental plates?

Back

Mountain building occurs due to the collision and compression of the plates.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another, often leading to volcanic activity.

Front

What type of boundary is characterized by plates sliding past each other?

Back

Transform boundary.

Front

What is an earthquake?

Back

A sudden release of energy in the Earth's crust that creates seismic waves.
