 GEOSPHERE EXPLANATION

The parts that make up our earth are called natural systems. There are four different types of natural systems which are the geosphere, hydrosphere, biosphere, and lastly the atmosphere. These spheres play crucial parts in our existence, and if they disappear there will be no life on Earth. I will be describing the geosphere, how it works, what it is, and what are the layers.

Geosphere is a name that scientists gave to all the rocks and layers of the Earth. Even though it sounds like we could live without rocks or the geosphere the Earth would not be here. The ground, hills, and any other part of the land that you stand on are created by the geosphere. What does the word Geo mean? Well, the word Geo means Earth it comes from Greek. Some people call the geosphere the lithosphere. Geo and lith mean similar things Geo means Earth and litho means stone.

You might ask what does the geosphere consist of? The geosphere consists of: soil, minerals, mountains, rocks, sand, hills, volcano, caves, canyons, craters, diamond, gold, and any other types of ores. Humans use the geosphere for their own need they use the land, mine in caves, and disturb the soil. The geosphere is important for human and animal extinction.

The layers of the geosphere are the layers that make up our Earth which are the inner core, outer core, mantel, and crust. The inner core is in the center of our Earth and it is the hottest layer. Next is the outer core and it is right over the inner core it is fully liquid, it is 2400 km thick and it is mostly made up of metal, nickel, and iron. After that is the mantle it is mostly solid and is the biggest part of the Earth's layers it is close to the size of the outer core it is approximately 2900 km. Now the crust the ground that all of us stand on. The thinnest layer is the crust because the thickest part is about only 30 km.

Overall the geosphere is very important for Humans, plants, trees, and animals extinct. Without the geosphere, the planet would not exist. So now do you know what the geosphere is what it is and what the layers are?
