How does the weather change?
The Earth is surrounded by an atmosphere, which covers the Earth.
When the atmosphere receives heat from the sun, it moves in various directions. Warm air heated by a stove rises, and the same thing happens on a global scale.
In the sky, warm and cold air masses are rising, falling, going sideways, and colliding with each other. This is wind.
In the atmosphere, there are various things such as water vapor, clouds, and rain clouds. These things move around the earth by the action of the wind, and where they move, they make it rain or snow. This is why the weather changes in various ways every day: sunny, cloudy, rainy, and so on.
In other words, weather changes as the atmosphere receives heat from the sun and moves from place to place.
