absorb

1. absorb 1

2. To soak up a liquid and take in nutrients or chemicals gradually.

3. abundant 2

4. Present in great quantity; more than adequate.

5. atmospheric (air) pressure 6

6. The downward pressure exerted by the weight of the atmosphere. It has an average value of one atmosphere at sea level but decreases as elevation increases.

7. altitude 7

8. The height of something above a particular specified level, especially above sea level or the Earth’s surface.

9. atmosphere 11

10. The layers of gases that surround earth or another planet.

11. conduction 20

12. The passage of energy through something, particularly heat or electricity by touching.

13. convectioncurrent 21

14. A circular current in a fluid like air, water, or molten rock. The process occurs when the fluid is unevenly heated so that part of the fluid rises, cools, and then sinks producing the circular movement.

15. decrease 24

16. To lessen or cause something to lessen in size, strength, or amount.

17. doldrums 26

18. An area with no wind or light variable winds just north of the equator in the Atlantic and Pacific oceans, situated between the trade winds. These caused problems for sailing ships.

19. electromagnetic radiation 28

20. Electromagnetic energy such as gamma rays, X-rays, ultraviolet light, visible light, infrared radiation, microwaves, and radio waves.

21. essential 29

22. Absolutely necessary.

23. exosphere 32

24. The outermost region of the atmosphere of the Earth or another planet.

25. explain 34

26. To make known in detail.

27. factor 35

28. Actively contributes to accomplishment, result or process.

29. greenhouse gases 39

30. Gases that are in the atmosphere that trap heat energy so that it cannot escape to space.

31. increase 47

32. The process of becoming or of making something larger in number, quantity, or degree.

33. infrared rays 49

34. The portion of the invisible electromagnetic spectrum consisting of radiation with wavelengths in the range 750 nm to 1 mm, between light and radio waves.

35. intersection 51

36. A point where lines or objects cross.

37. ionosphere 52

38. Four layers of the Earth’s upper atmosphere in which incoming ionizing radiation from space creates ions and free electrons that can reflect radio signals, allowing their transmission around the world.

39. land breeze 53

40. A breeze that blows from the land to the sea at night when the water is warmer than the land.

41. Mesosphere 55

42. Third layer of the atmosphere from the earth, coldest layer; as altitude increases, temperature decreases.

43. molecules 56

44. The smallest physical unit of a substance that can exist independently, consisting of one or more atoms held together by chemical forces.

45. ozone 59

46. A gaseous form of oxygen with three oxygen atoms per molecule, formed by electrical discharge in oxygen. It acts as a strong oxidizing agent and is used in water purification. O3

47. particle 60

48. A very small piece of something; any one of the basic units of matter, for example, a molecule, atom, or electron.

49. position 61

50. To put in place.
