Plate Tectonics

Front

What is the hypothesis of continental drift?

Back

The hypothesis states that the continents were once joined together in a single landmass and have since drifted apart.

Front

What are the three main types of plate boundaries?

Back

Convergent, Divergent, and Transform.

Front

What occurs at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to mountain formation or volcanic activity.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust, such as at mid-ocean ridges.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What landform is typically found at a divergent boundary between continental crust?

Back

Rift Valley.

Front

What causes plate movement?

Back

Plate movement is caused by convection currents in the mantle.

Front

What is the mid-ocean ridge?

Back

The mid-ocean ridge is an underwater mountain range formed by plate tectonics at divergent boundaries.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur due to tectonic plate movements.
