The atmosphere appears to be a static part of Earth; however, the air in the atmosphere moves and changes. How does the motion of air affect the oceans on Earth?

• It causes high tides and low tides in the ocean.

• It increases ocean levels, causing flooding on land.

• It raises water temperature, causing climate change.

• It creates wind, which partly controls the ocean’s currents.
