Across
- 1. a range of mountains that winds through the oceans.
- 3. exerted on Earth by the atmosphere; decreases with increased altitude
- 6. released into atmosphere by plants as they undergo photosynthesis
- 8. caused by unequal heating of the Earth's surface
- 9. a tide with the least difference between low and high tide.
- 10. upper part of thermosphere
- 11. Earth's magnetic field; traps harmful particles from the sun; causes northern lights
- 16. lowest layer; most atmospheric air is found here; extends 0-14km above Earth; virtually all weather occurs here
- 20. the gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent.
- 24. war air rises and cold air sinks causing a current of moving air
- 25. most takes place over the ocean.
- 26. "heat sphere," 8okm out into space; temp increases with height above Earth; Northern lights occur here; pace shuttle orbits here
- 27. the direct transfer of heat by light waves
- 28. layer of gases that surround the Earth
- 29. this causes tsunamis
- 32. the movement of energy through a body of water.
- 34. a canyon in the ocean floor.
- 35. daily rise and fall of Earth's waters on its coastlines.
- 36. clouds form as water vapor cools.
- 37. second layer from Earth; air temperature increases with height above Earth due to ozone absorption of sunlight; 14-50km above Earth
- 39. Earth's rotation on the direction of winds and currents.
- 40. a tide with the greatest difference between the heights of high and low tide.
Down
- 2. removed from the atmosphere by green plants
- 4. lower part of thermosphere
- 5. the incline beyond the edge of the continental shelf.
- 7. amount varies in the atmosphere; cycles through the water cycle
- 12. the horizontal distance between crests.
- 13. the contiguous process by which water moves through the living and nonliving parts of the environment. Sun is the energy source.
- 14. water droplets in clouds become heavy and fall back to Earth.
- 15. study of Earth's oceans.
- 17. third later from Earth; 50-80 km above Earth; air temp decreases with height above Earth; coldest layer; meteoroids burns up in this layer
- 18. huge mass of ice and snow that moves slowly over land formed in areas where more snow falls each year than melts.
- 19. gas absorbs solar radiation and releases it as heat, protects from harmful UV rays, located in stratosphere
- 21. the direct transfer of heat from one molecule to another in a substance through touch
- 22. water that fills the spaces in soil and rock layers.
- 23. a large stream of moving water that flows through the oceans.
- 30. the smooth, nearly flat region of the ocean floor.
- 31. removed from the atmosphere by bacteria and lightning; used by plants in growth and development
- 32. causes ocean surface currents.
- 33. at greater altitudes the same volume contains fewer molecules of gases; measured with a barometer
- 38. plants release water to air through leaves.
