Plate Tectonics ReTest

Front

What is a divergent boundary?

Back

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

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates collide, leading to one plate being forced beneath the other, often causing earthquakes and volcanic activity.

Front

What is a transform boundary?

Back

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

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle caused by the transfer of heat from the core, which drives the movement of tectonic plates.

Front

How do convection currents affect tectonic plates?

Back

Convection currents transfer heat from the Earth's core to the mantle, creating currents that cause tectonic plates to move.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by the upwelling of magma at divergent boundaries, where new oceanic crust is created.

Front

What evidence supports the theory of continental drift?

Back

Evidence includes the fit of continental coastlines, fossil similarities across continents, and geological similarities in rock formations.

Front

What are tectonic plates?

Back

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.

Front

What is the Ring of Fire?

Back

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