10. necessary for evaporation.
heat
Water molecules
Heat
Because of
It break the bonds that
hold water molecules
together.
11.
12. water evaporates from plants.
transpiration rates vary widely
depending on temperature, humidity,
wind and air movement, soil-moisture
availability and the type of plant.
15. process by which
water vapor in the air
is changed into liquid
water
WATER VAPOR
WATER
opposite of evaporation
16. As air rises it cools, combines with
dust, salt and smoke to form cloud
droplets.
When the water droplets in clouds
combine, they become heavy enough
to form raindrops.
17. small water droplets in an air-conditioned room.
Water droplets covering the inside of a window on a
cold day.
Moisture on the inside of car windows, especially
after people have been exhaling moist air.
22. Water soaks into the ground.
Water that infiltrates the soil
can either be taken up by
plants, evaporate, be stored
in the soil, or become
ground water.
EVAPORATE
23.
24.
25. process by which the
precipitation runs off
over the landscape
occurs when the rate of
precipitation is greater than
the rate of infiltration.
Ex. When rain hits saturated or
impervious ground, it begins to
flow overland downhill
26. Some water absorbs into the ground forming pockets of
water called groundwater.
Most groundwater eventually returns to the ocean while
other runs directly into lakes or rivers
Water that collects in rivers, streams and oceans is
called runoff
29. The water cycle helps to regulate the Earth’s
temperature.
The chemicals we use affect the water cycle.
Changes in climate means changes in water cycle.
Our cycle of water can be much older than you think.
We could be drinking the same water dinosaurs drank.
The water cycle only creates 1% useable water for
humans.
