BJHS Science 8 - Plate Tectonics Retest

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

Front

What is a convergent plate boundary?

Back

A boundary where two tectonic plates collide, often leading to mountain formation or subduction.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic activity.

Front

What is continental drift?

Back

The gradual movement of continents across the Earth's surface through geological time.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust due to tectonic plate movements.

Front

What is a volcanic eruption?

Back

The release of magma, gas, and ash from a volcano, often occurring at tectonic plate boundaries.

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate boundaries.
