What Are Clouds?

Clouds are beautiful things we see in the sky. They are made of tiny drops of water or ice crystals. These tiny pieces form when the air gets cold or has a lot of moisture. Clouds can look like many different shapes and sizes.

Where Do Clouds Live?

We see clouds in Earth's atmosphere. Scientists who study clouds call this field nephology. This is a part of meteorology, the science that helps us understand the weather. Clouds have special names based on where they are in the sky and what they look like. These names use both Latin and common words.

Why Are Clouds Important?

Clouds play a role in Earth's climate. They can reflect sunlight, which cools the planet. They can also trap heat from the ground, which can warm it. The height, shape, and thickness of clouds decide if they cool or warm the planet. Clouds higher up in the atmosphere have less impact. But clouds closer to the ground have a bigger impact on how warm or cool our planet stays.

Fun Cloud Facts

• The word "cloud" comes from old English words that meant a hill or a big piece of stone. People started using this word for rain clouds because they looked like piles of rock.
• Clouds can change color depending on the time of day and the light. During the day, clouds often look white on top and gray underneath. At sunrise or sunset, they can turn red, orange, or pink.
