The four earth spheres at north Marion high school.

We found examples of the biosphere by observing rocks and the chunks of broken earth. That was our examples of the lithosphere. We also had to find examples of the hydrosphere such as the creek at the back of the school, the puddles left by rain. We also studied the objects in the atmosphere like the birds and clouds since all the atmosphere is just the oxygen in the air. Really the four spheres are just four layers that cover the earth in a way.. easy to study and learn :)
