ELI5: Explain Like I'm 5

Earth system science

Earth system science is all about understanding how the different parts of the Earth - the air, the water, the land, and the living things on the planet - are connected and interact with each other. It's like thinking about the Earth like one big machine with many different pieces that all work together. Scientists study how the air, the water, and other parts of the Earth all work together to affect the climate, the way the land and plants grow, and how ecosystems work. By understanding how the Earth works, we can better understand how things like pollution, extreme weather, and climate change are impacting our planet.
