Facts: Water covers nearly three-quarters (75%) of the earth's surface. Most of the earth's surface water is permanently frozen or salty. Over 90% of the world's fresh water is found in Antarctica.

Precipitation - When the temperature and atmospheric Precipitation - When the temperature and atmospheric pressure are right, the small droplets of water in pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs.clouds form larger droplets and precipitation occurs.

Transpiration - As plants absorb water from the soil, Transpiration - As plants absorb water from the soil, the water moves from the roots through the stems to the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of it evaporates from the leaves, adding to the amount of water vapor in the air.water vapor in the air.
