Earth Science Ch 1 Test Review

Front

What is the process of forming new oceanic crust?

Back

Seafloor spreading is the process where new oceanic crust is formed as magma rises to the surface at mid-ocean ridges.

Front

What is the term for the shaking of rock in the Earth's crust?

Back

An earthquake is the shaking of the Earth's crust caused by the sudden release of energy in the Earth's lithosphere.

Front

What is a large section of the Earth's crust called?

Back

A tectonic plate is a massive, rigid slab of solid rock that makes up the Earth's lithosphere.

Front

What do we call the edge of a tectonic plate where it meets other plates?

Back

A boundary is the edge of a tectonic plate where it interacts with other plates.

Front

What pushes tectonic plates as hot magma rises, cools, and sinks again?

Back

Convection currents are the movements within the mantle that push tectonic plates due to the heat from the Earth's core.

Front

What is the theory that explains the movement of tectonic plates?

Back

The theory of plate tectonics explains how the Earth's plates move and interact, leading to geological phenomena.

Front

What is the term for the boundary where two tectonic plates move apart?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in seafloor spreading.

Front

What is the term for the boundary where two tectonic plates collide?

Back

A convergent boundary is where two tectonic plates collide, which can lead to the formation of mountains or subduction zones.

Front

What is the term for the boundary where two tectonic plates slide past each other?

Back

A transform boundary is where two tectonic plates slide horizontally past one another, often causing earthquakes.

Front

What is the molten rock beneath the Earth's surface called?

Back

Magma is the molten rock located beneath the Earth's surface, which can erupt as lava during a volcanic eruption.
