Unit 4 Earth's Internal Processes

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What landform is typically found at a divergent boundary between oceanic crust?

Back

Mid-Ocean Ridge.

Front

What landform is typically found at a divergent boundary between continental crust?

Back

Rift Valley.

Front

How do temperature, pressure, and density change as you move from the crust to the inner core?

Back

They all increase.

Front

What part of Earth's interior is believed to have convection currents that cause tectonic plates to move?

Back

Asthenosphere.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates collide, often leading to the formation of mountains or subduction zones.

Front

What happens at a transform boundary?

Back

At a transform boundary, two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, composed of solid rock and is where we live.

Front

What is the mantle?

Back

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

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, composed mainly of iron and nickel, and is responsible for Earth's magnetic field.
