Use the information to answer the question. The tables show the speeds of P-waves as they pass through different materials and their speeds through different layers of Earth. Which statement best describes the movement of P-waves?

• P-waves travel faster near Earth’s surface.

• P-waves travel the same speed in all types of rocks.

• P-waves travel slower in solids.

• P-waves travel faster in dense materials.

Use the information to answer the question. The tables show the speeds of P-waves as they pass through different materials and their speeds through different layers of Earth. What does the data about P-waves show about the layers of Earth?

• The crust does not contain soft rocks.

• The mantle is more dense than the crust.

• The outer core is hotter than the inner core.

• The inner core is mostly made of liquid.
