🌦️ How Weather Works
Discover how the sky makes rain, clouds, wind, and storms!
What you’ll learn
- Explain how the Sun's heat drives the water cycle to make clouds and precipitation.The Sun warms Earth and turns water into vapor through evaporation. The vapor rises, cools, and condenses into cloud droplets. When clouds get too heavy, water falls as rain, snow, or hail.
- Describe how wind, storms, rainbows, and seasons create different weather.Wind is moving air caused by uneven heating. Storms build electricity that makes lightning and thunder, and sunlight through raindrops makes rainbows. Earth's tilt gives us changing seasons and different weather through the year.
Questions this course answers
What gives Earth the energy that creates almost all weather?
The Sun warms the land, air, and water, which starts the movement that creates all our weather.
What is a cloud actually made of?
Clouds form when water vapor cools and turns into millions of tiny water droplets floating in the sky.
What is it called when water changes into invisible vapor in the air?
Evaporation is when the Sun's heat turns liquid water into an invisible gas called water vapor.
What is wind?
Wind is simply air on the move, caused when warm air rises and cooler air rushes in.
Why do you see lightning before you hear thunder?
Light travels faster than sound, so the flash reaches you before the boom of thunder.
Why does Earth have different seasons?
Earth's tilt means each part leans toward or away from the Sun, creating warmer and colder seasons.
