Evaporation & Transpiration

Both are caused by the sun’s heat.

Evaporation

Water begins its journey as a liquid in streams,

rivers, ponds, lakes, and oceans…even puddles! It is in a liquid state and sits on the earth because it is

heavier than air.

Evaporation

When the sun heats up the water, the water turns into vapor (tiny molecules of water) and heads for the sky.

When water evaporates it is lighter than air.

Transpiration

Just as we sweat, so do plants!

Return to

Table of

Transpiration

Plants absorb water from the soil. Each plant will use the water that it needs to help it grow. As extra water travels

through the plant and to its leaves, it is pulled out and evaporated into the air. This process is called transpiration.

Condensation

CondensationDid the water leak through the glass? No! It came from

the air! Water vapor in the air became cooler when it touched the cold glass, causing it to became liquid again!

Condensation

When water vapor goes up into the air, it becomes colder and gathers with millions of other tiny molecules of water

to create all of the beautiful clouds in our skies!

Condensation

Did you notice something about the process of condensation? It is the OPPOSITE of evaporation!

Why is that?!

Return to

Precipitation

Some things are just too heavy to hold!

Return to

Cont

Precipitation

We get precipitation when so much condensed water has become too heavy for the atmosphere to hold on to.

Return to

Table of

Cont

Precipitation

The clouds get so packed with water molecules that they become heavy and much colder. As the evaporation cools, it

turns back into water and falls down to the ground.

Now, let’s put it all together into The Water Cycle

First, we get heat from the sun…

…which evaporates the water…

…and precipitates once it cools and becomes heavy…

…then collects in and on the earth.

…that goes into the air and

condenses…

Thus, completing The Water Cycle!
