The Earth has water.  Water is in lakes, rivers, and oceans.  Water can be in the air.  Clouds are made of water.

The Sun heats water in lakes and oceans.  The water becomes water vapor in the air.  The warm air makes the water vapor go high into the sky.  It is colder up high in the sky.  In the colder air the water vapor becomes water droplets.  This makes clouds.  The clouds make rain and snow.  The rain and snow fall onto Earth.  The water in rain and snow goes to lakes, rivers, and oceans.  This is called the water cycle.

Water vapor are tiny droplets of water in the air.  We cannot see water vapor.  Sometimes we can feel it, when it feels warm and sticky out.  We are feeling the water vapor.

The sunlight can warm water and turn some of it into tiny droplets.  We cannot see the droplets.  The droplight rise into the. air. These droplets are called water vapor.

There can be tiny water droplets in the air called water vapor.  We cannot see water vapor.  When it gets cooler, the water vapor can becomes water droplets.  This can make clouds in the sky.  A cold can of soda on a hot day can get water droplets on the outside.  Water vapor colling to becomes water droplets is called condensation.

Water droplets can fall from the sky as rain, snow, or sleet.  This is called precipitation.  Precipitation is water droplets falling from clouds.

The sunlight warms water in lakes and oceans.  The water becomes water vapor.  The water vapor rises into the sky.  It is colder up high in the sky.  The water vapor gets colder and becomes water droplets.  This is a cloud.  A cloud is water droplets in the sky.  

Water droplets can fall from a cloud.  This is called rain.

Water droplets can freeze in a cloud.  The frozen water droplets are snowflakes.  Snowflakes can fall to the ground.  This is called snow!

When rain is falling from the sky we say it is raining.

When snow is falling from the sky we say it is snowing.
