57. reservoir

58. soil

59. a place where large amounts of water are stored for future use. Reservoirs are like lakes; they may be natural or made by humans.

64. a glacier that forms in the V-shaped valley formed by a river.

65. water cycle

66. water vapor

67. the process by which water moves through the ground, evaporates from earth into the air, forms clouds, and falls back to earth as rain or snow.

68. water in its gaseous state.
