Unit 3 Plate Tectonics Mission Review 2024

Front

What is the theory of continental drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What technology helped map the ocean floor and supported the theory of continental drift?

Back

SONAR (Sound Navigation and Ranging) is used to map the ocean floor.

Front

What occurs at the borders of major tectonic plates?

Back

Earthquake and volcanic activity is evident at the borders of major tectonic plates.

Front

What are seismic waves?

Back

Seismic waves are vibrations that radiate outward from movement in the Earth.

Front

What is the outcome of hotspots in geology?

Back

Hotspots can lead to the formation of islands due to volcanic activity.

Front

What is tectonic stress?

Back

Tectonic stress is the force applied to rocks in the Earth's crust, which can lead to deformation.

Front

What are the three types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What happens at divergent boundaries?

Back

At divergent boundaries, tectonic plates move apart, leading to the formation of new crust.

Front

What happens at convergent boundaries?

Back

At convergent boundaries, tectonic plates collide, which can cause earthquakes and volcanic activity.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other, causing friction and earthquakes.
