Plate Tectonics Flashcard

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movement of Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere beneath.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are convergent, divergent, and transform boundaries.

Front

What occurs at convergent boundaries?

Back

At convergent boundaries, tectonic plates collide, leading to the formation of mountains, earthquakes, and volcanic activity.

Front

What is a hot spot volcano?

Back

A hot spot volcano is formed when magma from deep within the Earth rises to the surface, often creating islands, such as the Hawaiian Islands.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.

Front

What type of volcano is typically more explosive?

Back

Hot spot volcanoes are usually more explosive than subduction boundary volcanoes.

Front

What geological feature is formed at divergent boundaries?

Back

Divergent boundaries often lead to the formation of mid-ocean ridges and rift valleys.

Front

What is the primary movement at transform boundaries?

Back

The primary movement at transform boundaries is lateral sliding, where plates slide past each other.

Front

Where are the Alps located?

Back

The Alps are located on the Eurasian Plate.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.
