Ch. 3 Section 1 Earth Dynamics

Front

What is the Inner Core?

Back

The Inner Core is the innermost layer of the Earth, composed primarily of iron and nickel, and is solid due to the immense pressure.

What should you be aware of after an earthquake if you are at the beach?

Back

You should be aware of a tsunami, which is a series of ocean waves caused by the displacement of a large volume of water.

Front

What happens to temperature as you move from the crust to the core?

Back

Temperature increases as you move from the crust to the core.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a physical layer of the Earth made of rock that flows slowly, allowing tectonic plates to move on top of it.

Front

What is convection?

Back

Convection is the transfer of thermal energy caused by the rising of hotter, less dense fluids and the sinking of cooler, more dense fluids.

Front

What is the Crust?

Back

The Crust is the outermost layer of the Earth, consisting 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 layer of the Earth beneath the mantle, composed of liquid iron and nickel, and is responsible for Earth's magnetic field.

Front

What is the Lithosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What is an Earthquake?

Back

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