The question is a bit tricky! It sounds like you're asking about Earth's atmosphere and hydrosphere, which are the layers of air and water that surround our planet.

Here's a breakdown:

* Atmosphere: This is the layer of gases that surrounds Earth. It's essential for life because it provides oxygen to breathe, protects us from harmful solar radiation, and helps regulate temperature.

* Hydrosphere: This includes all the water on Earth, including oceans, lakes, rivers, ice, and groundwater. It plays a vital role in Earth's climate and supports a vast array of life.

It's important to remember that the Earth's structure is also made up of the lithosphere (the solid, rocky outer layer) and the mantle (a layer of hot, semi-solid rock). However, these are internal layers and not what surrounds the planet.

Let me know if you'd like more details about any of these layers!
