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 geologic feature is commonly found at divergent boundaries?

Back

Rift valleys and mid-ocean ridges.

Front

What occurs at convergent boundaries?

Back

Plates move towards each other, leading to mountain building, subduction, or volcanic activity.

Front

What is a transform boundary?

Back

A boundary where two tectonic 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 is a hotspot?

Back

A location where magma from deep within the mantle rises to the surface, often creating volcanoes.

Front

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

Back

Temperature increases as you go deeper into the Earth.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.
