Plate Tectonics Regents Review

Front

What is Plate Tectonics?

Back

The theory explaining the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is Continental Drift?

Back

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

Front

What is the difference between Oceanic and Continental Crust?

Back

Oceanic crust is denser and thinner than continental crust, which is thicker and less dense.

Front

What is the Pacific Plate?

Back

The largest tectonic plate, located beneath the Pacific Ocean, known for its significant geological activity.

Front

What causes tectonic plates to move?

Back

Convection currents in the mantle, driven by heat from the Earth's core, cause the movement of tectonic plates.

Front

What is a subduction zone?

Back

A region where one tectonic plate moves under another, leading to geological activity such as earthquakes and volcanic eruptions.

Front

What is the significance of the Ring of Fire?

Back

An area in the Pacific Ocean basin known for its high levels of seismic activity and numerous volcanoes, due to tectonic plate boundaries.

Front

What is a fault line?

Back

A fracture in the Earth's crust where blocks of land have moved past each other, often associated with earthquakes.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle's semi-fluid properties allow tectonic plates to float and move on its surface.

Front

What is an earthquake?

Back

A sudden release of energy in the Earth's crust that creates seismic waves, often caused by tectonic plate movements.
