The Geosphere 01: Structure of the Earth

The earth works in spheres. These spheres coexist, and work together in different ways to help life on earth grow, prosper, and continue to be productive.

It is important to learn about all of these spheres, and know that the geosphere directly affects all of the other spheres on earth, which is why understanding it is vital.

To start, we must define geosphere for what it is: any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.

The atmosphere deals with all of the gases surrounding the earth. One way that the atmosphere and geosphere coincide is through the interaction of volcanoes. When volcanoes erupt, they release gas able to oxidize other elements it into the air, thus creating a relationship between the two spheres.

The biosphere deals with the surface regions of the atmosphere, and hydrosphere on earth occupied by living organisms. In this way, the soil on the ground provides nutrients to plants, and the tectonic plates determine circumstances on earth that can either be harmful or dismissable. The two, thus work together to keep us healthy and safe.

The hydrosphere is all the water found on earth. The geosphere and hydrosphere work together through tectonic plate activity (the presences of tsunami's), and through the overall shape of the earth. Because of earths shape, it is able to dictate where and how water travels throughout, creating a harmony between the two spheres. 

The last sphere to look at is the cryosphere, which deals with all of ice on the earth. The two work together in terms of terrain.


To continue our investigation of our earth's structure, we will look at layers of the earth.

The lithosphere is the crust and apart of the upper mantle, and the asthenospheric mantle is towards the bottom portion of the upper mantle, thus the two are apart of each other. In addition, there is the lower mantle, and the outer core of the earth, all varying in degrees and thickness.

Therefore, the geosphere affects all of the Earth and its layers.
