Warm-UpWarm-Up1)What do you do when you’re

thirsty and you want some water? Is this the same for everyone around the world?

2) Do you think that the majority

of the Earth contains usable water? Explain why or why not.

• What is the WATER CYCLE?– Water constantly moves among the

oceans, the atmosphere, the lithosphere, and the biosphere. This unending circulation of Earth’s water supply is the water cycle.

The Water CycleThe Water Cycle• The continuous circulation of Earth’s

water supply.

• Water moves among the oceans, atmosphere, lithosphere and the biosphere

• The energy source for the water cycle comes from the sun

The Water CycleThe Water Cycle

• WC is balanced meaning that the average annual precipitation over Earth EQUALS the amount of water that evaporates. (What goes up comes down)

• Evaporation exceeds precipitation over water and precipitation exceeds evaporation over land

• WC is balanced meaning that the average annual precipitation over Earth EQUALS the amount of water that evaporates. (What goes up comes down)

• Evaporation exceeds precipitation over water and precipitation exceeds evaporation over land

• How does the law of conservation of matter relate to the water cycle?– Water is never created or destroyed. It

just cycles through different forms in what we call the water cycle.

WATER CYCLE BALANCEWATER CYCLE BALANCE

• Because water is never created or destroyed, the water cycle is balanced.

• Balance in the watercycle means that the average annual precipitationover Earth equals theamount of water that evaporates

• Because water is never created or destroyed, the water cycle is balanced.

• Balance in the watercycle means that the average annual precipitationover Earth equals theamount of water that evaporates

WATER CYCLE BALANCEWATER CYCLE BALANCE

• There are local imbalances– Ex: over the ocean, more water

evaporates than precipitates– Ex: over land, more water precipitates

than evaporates
