How Do We Know What the Earth Looks Like from Space?

Imagine you're on a really high swing, and every time you go up, you can see more of the playground. That's like how satellites work, they go around Earth and take pictures from way above. These pictures help us know what Earth looks like from space.

Satellites have cameras that take lots of photos as they zoom around the planet. Sometimes, they even use special kinds of light we can’t see, like infrared or ultraviolet, to show us things like hot spots or glowing plants.
