Discover the Amazing Water Cycle: Evaporation, Condensation & Precipitation

The water cycle is the way water moves around Earth again and again. It never stops water keeps traveling through the same steps over and over. That is why it is called a cycle!

Water moves through three main steps: evaporation, condensation, and precipitation. You can see parts of the water cycle happening all around you every day.

Evaporation happens when the sun heats liquid water and turns it into an invisible gas called water vapor. The water vapor rises up into the air.

You can see evaporation when a puddle slowly shrinks on a sunny day, or when wet clothes on a clothesline dry out in the warm sun. Most of the water that evaporates on Earth comes from the large oceans, lakes, and rivers that cover our planet.

Condensation happens when water vapor rises high into the sky, where the air is very cool. The water vapor cools down and turns back into tiny liquid water droplets. These droplets group together to form clouds.

You can see condensation on a small scale when water droplets appear on the outside of a cold glass on a warm day. The warm air around the glass cools down and water vapor turns into liquid drops. Dew on grass in the early morning forms the same way water vapor in the cool night air condenses on the grass.

Precipitation is any water that falls from clouds down to the ground. It can fall as rain, snow, sleet, or hail depending on the temperature.

Snow forms when water vapor in clouds freezes into ice crystals that fall as soft white flakes. Hail forms inside tall storm clouds when water droplets are tossed up and down by strong winds and freeze into balls of ice. After precipitation falls, water flows into rivers as runoff, soaks into the soil to become groundwater, or evaporates again to continue the cycle.

Water Cycle: The water cycle is the continuous journey water takes as it moves around Earth through evaporation, condensation, and precipitation repeating over and over without stopping.

Evaporation: Evaporation is when liquid water is heated by the sun and changes into an invisible gas called water vapor, which rises into the air. You see this when a puddle disappears on a sunny day.

Condensation: Condensation is when water vapor cools down and turns back into tiny liquid water droplets. This is how clouds and dew form.

Precipitation: Precipitation is water that falls from clouds to the ground. Rain, snow, sleet, and hail are all types of precipitation.

Water Vapor: Water vapor is water in its invisible gas form. You cannot see it, but it floats in the air all around you after evaporation occurs.

Clouds: Clouds are made of millions of tiny water droplets or ice crystals that float in the sky. They form through condensation high in the atmosphere.

Runoff: Runoff is water that flows over the surface of the land into streams and rivers after heavy rain or snowmelt.

Groundwater: Groundwater is water that soaks into the soil after precipitation and is stored underground.

Dew: Dew is the tiny drops of liquid water that form on grass and leaves in the early morning when water vapor condenses on cool surfaces overnight.

Cycle: A cycle is a process that repeats the same steps over and over without stopping. The water cycle has been running on Earth for billions of years.

Hail: Hail is a form of precipitation that falls as small balls of ice. It forms inside tall storm clouds during thunderstorms.

Snow: Snow is a form of precipitation that falls as soft white flakes. It forms when water vapor in clouds freezes into ice crystals high in the sky.

You can observe the water cycle in your everyday life! Watch a puddle on a sunny day and notice how it slowly shrinks that is evaporation at work. Look at the sky and find clouds those formed through condensation.

Next time it rains or snows, you are watching precipitation happen. You can also try placing a cold glass of water on a warm day and watch water droplets form on the outside that is condensation you can see up close!

Understanding the water cycle is an important part of learning about Water Systems. As you explore this topic, you are building a strong foundation in Earth science that will help you understand weather, nature, and how our planet works.

You are learning how the same water on Earth has been recycled for billions of years the water you drink today may have once fallen as rain in a faraway place long ago!

The water cycle is a key part of understanding Water Systems on Earth. As you continue your science journey, you will discover how the water cycle connects to weather patterns, living things, and the environment around you.

The three steps you learned evaporation, condensation, and precipitation work together to move fresh water to plants, animals, and people all over the world. Without the water cycle, living things would not get the fresh water they need to survive.
