Earth Layers

Which statement BEST describes one difference between Earth's mantle and crust?

• The mantle is less dense than the crust.

• The mantle is hot compared to the crust.

• The mantle is cool compared to the crust.

Which description best represents heat flow and movement in Earth's mantle?

• When magma is heated, it becomes more dense and sinks. When magma is cooled, it becomes less dense and rises.

• When magma is heated, it becomes less dense and sinks. When magma is cooled, it becomes more dense and rises.

• When magma is heated, it becomes more dense and rises. When magma is cooled, it becomes less dense and sinks.

• When magma is heated, it becomes less dense and rises. When magma is cooled, it becomes more dense and sinks.

The picture below shows a model of Earth's layers. Which is Layer 3?

• It is the mantle, composed of solid, high density rock.

• It is the mantle, composed of semi-liquid, slowly moving rock.

• It is the outer core, which forms a cool, rigid shell around the inner core.

• It is the lithosphere, which forms a rotating, liquid layer around the mantle.
