Earth observation

Earth observation is like having a camera that takes pictures of our planet from far away. Scientists use special cameras on satellites that orbit around the Earth to take pictures of different parts of our planet. They can see things like land, water, and even clouds from really high up in the sky.

The pictures that these cameras take are very helpful to scientists because they can help them to understand how the Earth is changing. For example, the scientists can compare pictures from one year to the next to see if a forest is getting smaller or if a city is getting bigger. They can also study the weather by looking at pictures of clouds and storms.

Earth observation helps us to learn more about our planet, how it's changing, and how we can better take care of it.
