Final Exam 1 *1*

Geo-sphere, Atmosphere, Hydrosphere, and Biosphere


*Geo-sphere*
Is the solid earth that includes continental and oceanic crusts well as the various layers of earths interior. The surface is in constant motion which gives us our lands shapes. Every day people are creating erosion which is a very important thing to know. The earth as we know it is wearing away and it's all because of human life.


*Atmosphere*
when volcanoes erupt a huge amount of sulfur dioxide is released into the atmosphere which cools the climate in time. This effects the air pollution and makes it harder for people to live. The air becomes much more dense and is hard for plants to survive sense the sun is blocked and there is not much sun. Industrial and agricultural activities have also changed the composition of the atmosphere.


*Hydrosphere*
Water is the main reason for chemical and mechanical erosion of the earths surface. When water moves it breaks down rocks that will eventually break down to minerals and will be carried to the ocean. Pollution is ruining our water and pretty soon it will be to late to save it. water is a main source of every ones life and without it we would be tragic.



*Biosphere*
The biosphere is the life zone of the Earth and includes all living organisms, including man, and all organic matter. If we did not have a biosphere our planet would be just like the others and no life. Keeping our planet clean is very important but if we let go and just didn't care life would start to die off. To live we need plants, water, and air but we also need to keep organisms and all life to stay alive.


I will use this information in the future when I want to figure out the weather and what our earth really is. People say to keep our earth clean we dont need fuel efficient cars and we just need to clean up more but their wrong the fuel efficient cars help the air and help our health. People also say that our air is fine when really people die every day because our air is getting worse over the years.
