In Our World


A weather front coming in across the sky.

There is a lot to learn about weather. Sometimes there is snow. Sometimes there is rain. Sometimes there is sunshine. Sometimes there is even hail or sleet . There are reasons for all these types of weather.


Clouds have a lot to do with weather. Some days white clouds sit in the sky. Some days clouds block out the sun. Big gray clouds can even cover the sky. Rain and snow both come from the clouds.

A cloud's color can tell us a lot. Clouds are densely packed with water particles. These particles stop sunlight from penetrating the cloud. Because of this, sunlight is reflected back out. This is why clouds appear white to us.


Cloud formation is an interesting process. It is also related to weather. First, warm air absorbs water vapor. Then, the wator vapor and warm air rise. It rises because water vapor is lighter than air.

As the mixture rises, the air cools. This causes the vapor to condense . When the vapor condenses, it comes out of the air. It comes out as micro-droplets. These micro-droplets are the particles densely packed in clouds.

Over time, the micro-droplets may combine. They combine to form larger droplets. These larger droplets may combine and form raindrops. When they are large enough, they fall. We know this as rain.


Clouds are an important part of our world. They are very important to our weather system. Next time you are outside, look at the clouds. Think about what is happening inside of them.
