Geologic Processes

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is the inner core of the Earth?

Back

The inner core is the solid, innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

Front

Which layer of the Earth is the hottest?

Back

The inner core is the hottest layer of the Earth, with temperatures reaching up to 5,700 degrees Celsius.

Front

What is erosion?

Back

Erosion is the process by which materials are moved across the Earth's surface by natural forces such as water, wind, and ice.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, consisting of solid rock and soil.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide, often causing one plate to be forced beneath the other, leading to mountain formation or volcanic activity.

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 is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass.

Front

What materials make up the outer core?

Back

The outer core is composed of liquid iron and nickel, and it surrounds the inner core.
