• the weight of the atmosphere

• the strength of Earth’s magnetic field

During the day, water from the ocean is transferred to the atmosphere. Which statement describes the energy change that takes place during the transfer?

• The ocean is cooled when energy is transferred from the atmosphere to the ocean.

• Ocean waves speed up when energy is transported from the ocean to the atmosphere.

• Ocean waves slow down when energy is transported from the atmosphere to the ocean.

• The atmosphere is warmed when energy is transferred from the ocean to the atmosphere.

Which statement best describes the movement of heat energy in the global ocean?

• Heat energy is transported to the equator from the continents.

• Heat energy in deep currents is transported to the ocean’s surface.

• Heat energy in warm surface currents is transported to areas near Earth’s poles.

• Heat energy is transported from areas of lower temperature to areas of higher temperature.
