Across
- 3. that block transmission of heat back to space and insulate Earth/ greenhouse gas
- 4. ocean currents that move parallel to the Equator/ equatorial current
- 6. winds that blow from west to east at middle latitudes/ westerlies
- 7. winds that blow from east to west toward the Equator, replacing the hot air that rises at the Equator/ trade winds
- 9. spiral change in the movement of water in the water column when the water is pushed by wind/ ekman layer
Down
- 1. in the northern Indian Ocean that blow from the southwest in summer and from the northeast in winter/ monsoons
- 2. winds that blow at high latitudes/polar easterlies
- 5. (O3) in the atmosphere that deflects ultraviolet radiation, which is harmful to life/ ozone layer
- 6. process by which colder water rich in nutrients rises from a lower to a higher depth/ upwelling
- 8. division between the troposphere and the stratosphere 12–20 km above Earth’s surface/ tropopause
