The Earth, or our Ecosphere, is made up of different layers, both living and non-living.
Before, we saw that the Earth’s interior is made up of four layers: the crust, mantle, outer core, and inner core.
The exterior, where we can directly observe, has four “spheres” as well. They are the biosphere, which is made up of all living things on Earth such as animals, bacteria, and plant life. Then there is the hydrosphere, which is made up of all bodies of water like oceans, rivers, and glaciers. The third sphere is the atmosphere, which is the envelope of gases surrounding the Earth, including the air, the ozone layer, and greenhouse gases. The fourth sphere is the lithosphere (or the crust), which is made up mostly of rock and it has our tallest mountains and deepest caves. How do humans affect each sphere? Is our influence a benefit to the Earth?

I remembered that we did this in class and talked about how we affect this “spheres”by cutting down polluting etc

I found this interesting because in the beginning I thought that the spheres of Earth were just the layers of the Earth. One way humans can affect each sphere is by polluting. Another way humans can affect each sphere is by destroying animals homes.(Deforestation)
