In my reading group we have been working on science about the earth. We learned about all of the spheres around the world like the Geosphere and the hydrosphere and the biosphere and we all know the atmosphere. And without them we would not be alive and even if just one of the spheres were gone then we would have a very big problem.
If you are wondering what all of the spheres are then I have the answer for you. The biosphere is nature like all the plants and trees and grass and without the biosphere we would not be able to breath.
The geosphere is stuff like lava and rocks but mostly rocks and without the geosphere there would be no earth. the hydrosphere is water and without water there would be no fish no humans. The last one is the atmosphere it's our air our what we breath and with no air we would not be here.
Then on our last activity we found out there was more water than land there was 71 percent water and 29 percent of land I. Think that science is very interesting and fun it's now one of my hobbies.
