Plate Tectonics Concepts Assessment

Front

What is a divergent plate boundary?

Back

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

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 plate boundaries.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often leading to one plate being forced beneath another, creating subduction zones.

Front

What is a transform plate boundary?

Back

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

Front

What evidence supports the theory of plate tectonics?

Back

Evidence includes the fit of continents like puzzle pieces, fossil distribution, and geological similarities across continents.

Front

What is subduction?

Back

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

Front

What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were joined together.

Front

What is the significance of the Ring of Fire?

Back

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

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

Front

What is the mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and core, where convection currents drive plate tectonics.
