Earth Science Matter

When an earthquake wave passes from the crust to the mantle, the wave

• reverses direction.
• changes speed.
• increases energy.
• stops moving.

 The inner core of Earth is solid because of the

• rate of rotation.
•  extreme temperature.
•  amount of pressure.
•  magnetic field.

This circle graph shows that two common elements make up about 75% of a specific type of matter. Which type of matter does the circle graph MOST likely represent?

•  Earth’s atmosphere
•  living organisms
• ocean water
• Earth’s crust

Which section of Earth is composed primarily of liquid metal?

• crust
• mantle

 A difference between the oceanic crust and the continental crust is that the oceanic crust is

• composed chiefly of sedimentary rocks.
• more dense than the continental crust
• older than the continental crust.
• continually being created.
