• Most of the water on earth is either salt water or ice and CAN'T easily be used by living things

Water Cycle

• Water MOVES through the environment through processes such as condensation, evaporation, transpiration, precipitation, and surface runoff

• Water is STORED in many places including oceans, lakes, in the ground, rivers, snow, ice, clouds, plants and animals.

• Rain

• the Sun

• Runoff

• Radiation

Earth's fresh water is not evenly spread around the globe

Some areas have more water than others. Latitude, geography, topography, and ocean and atmospheric currents all affect where fresh water can be found.

Water and Life

All living things need water to survive. BUT about 1/3 of the Earth's land is covered by deserts with very little water. Animals and plants have developed special adaptations to collect, store and use as little water as possible.
