describe the water cycle
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

what is waters specific heat
The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance.
500
is oxygen a polar molecule? explain.
yes because it has both a positive and negative charge.

describe the water cycle.
he water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle. Water keeps moving and changing from a solid to a liquid to a gas, over and over again.
