Answer:

Water Cycle Step #1: Water evaporates from the Earth’s surface.

water evaporates from earth's surface

If you spill a glass of water outside you will notice that a few hours later the water is gone! That is because water slowly turns from a liquid into a gas called water vapor. The process of water turning from a liquid into a gas is called evaporation.

Evaporation happens faster on a hot day. That is because the evaporation of water outside is powered by the sun! The hotter it is outside, the faster water will evaporate. Since water in its gas form has no color, we cannot see it. It just goes into the air.

Water Cycle Step #2: Water condenses to form clouds.

Water vapor rises up in the sky due to the sun’s heat. Once the water vapor rises high enough it condenses into water droplets. Condensation is the process of water turning from a gas into a liquid.

You have probably experienced condensation if you have had a cold glass of water at a restaurant. As the cold glass sits on the table, water vapor from the air condenses into water droplets on the glass. The same thing happens as water vapor rises into the sky – it turns into liquid water.

It’s important to remember that not ALL water condenses to form clouds. Some of it condenses close to the ground to form dew and some of it rises up only a little bit to form fog, but most of it rises high in the sky to form clouds.

Fun fact: Clouds are made of tiny water droplets — billions and billions of them!

Water Cycle Step #3: Water falls back to the Earth as precipitation.

When water droplets get heavy enough, they fall back down to Earth as rain! We call this precipitation because it can happen in a few different ways: rain (liquid water), snow (frozen water), and hail (big pieces of frozen water). Precipitation brings the water back down to earth and the cycle repeats … the sun shines on the water and it starts evaporating again. This is why we call it the water cycle.

The water cycle is constantly happening every day for millions of years!

The water in a water bottle wasn’t made last week or even last year – it could be the same water that passed through a dinosaur millions of years ago. It ends up in your water bottle thanks to the water cycle, which is always happening. After the dinosaur went to the bathroom on the ground that water evaporated to form water vapor in the air, which rose up in the sky to form clouds. Then it fell back down to Earth as rain, which probably ended up in a river, and then thousands of cycles later that water ended up in your water bottle.

WATER CYCLE EXAMPLES

clothing hanging outside dry due to evaporation

Drying clothes outside.

Before people had drying machines they washed their clothes and then dried them outside. This is possible because of evaporation (water turning from a liquid into a gas).
