Which statement below best describes the Earth's crust?

• It is stationary and unable to move
• It is thicker than the mantle and the core.
• It is located between the outer and inner core.
• It is composed of continental and oceanic plates.

How is energy from the sun transferred to earth?

• by conduction
• by convection
• by radiation
• by the force of gravity

The composition of earth from its surface to center is 6,300 km down can be studied using seismic waves. There are two basic types, S-waves and P-waves. Students studying earth's interior are given the information below about P & S waves and how they travel through earth. Select the statement below that CANNOT be concluded from the information below.

• There is a change in density occurring at 30 km.
• There is a liquid layer from 2,900 km to 5,200 km.
• There is a boundary between solid and liquid layers at 30 km.
• There is a density change that occurs at 2,900 and 5,200 km.

Earth's inner core is

• a dense ball of solid metal.
• a layer of molten metal.
• a layer of hot partially melted rock.
• a layer of rock that forms Earth's outer skin.

Which of the following best describes the mantle?

• molten metal
• dense, solid metal ball
• hot but solid rock
• dry land and ocean floor

From all the data that scientists have collected, they have concluded that the Earth's interior is made up of

• continents
• several layers
• ridges and trenches
• only one or two layers
• marshmallow

When you heat up an object, do the particles in that object move more, move less, or move the same rate as they did before?

• move more
• move less
• move at the same rate
