The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water and soil due to heat from the sun, rises into the atmosphere and cools to form clouds, and falls back to Earth as precipitation in forms such as rain, snow, or hail. The water then either runs back into bodies of water through runoff, or sinks into the ground to become groundwater, completing the cycle.

1. Water travels in a cycle yes it
does.

2. The water cycle is driven by the
sun
• Water is always
moving
• Evaporation
• condensation
• precipitation
• transpiration

3. Evaporation
• Heat causes liquid
water to turn into a gas
• everyday tons of water
evaporates from
oceans, lakes, rivers,
& moist soil
• This warm gas rises

4. Condensation
• As water vapor cools
it turns from a gas to a
liquid
• when a large amount
of water vapor
condenses on dust
particles, a cloud
forms

5. Types of condensation
• Humidity
• dew
• frost
• fog

6. Precipitation
• Water falling back to
Earth
• when water in the
clouds gets to heavy,
then gravity goes to
work

7. Types of precipitation
• Rain
• sleet
• snow
• hail
• drizzle
• dew

8. Runoff
• After precipitation,
water that runs back
into a river, lake, or
ocean

9. Groundwater
• Some rain soaks into
the soil forming
pockets underground
• eventually most of this
returns to a larger
body of water

10. Transpiration
• Loss of water vapor
from plants
• Evaporates out
through the leaves

11. How does this affect weather?

12. ???????????????
• What causes evaporation?
• Where on Earth does evaporation occur?
• What causes condensation?
• How do mountain ranges affect the water
cycle?
• How does temperature affect precipitation?
