Earth's Spheres

Lithosphere:


      The lithosphere contains all of the solid land of the earths crust. The semi solid parts underneath the crust and the liquid part near the center of the earth. Basically how deforestation effects the lithosphere is by changing the land scape. Tree's and other forms of vegetation prevent soil erosion but when deforestation occurs there is no plant life to absorb the excess water. After deforestation occurs the soil is left nutrient poor, after this the land is unusable and plant life can no longer grow. The chemical compounds that are found in the soil change due to the lack of vegetation.

Lithosphere

Atmosphere:

      Tree's take carbon dioxide from our atmosphere and through the process of photosynthesis they create food for themselves but they also release oxygen into the atmosphere for human and other life forms to breath. The more tree's we have the better our atmosphere will become. Since we emit a lot of carbon dioxide from everyday activities such has breathing, using machinery and cars. A layer of carbon dioxide is formed by the ozone layer making it thicker, this is not a good thing. This is the green house effect, changing climate temperatures are occur because the suns ultra-violet rays are being tapped by this layer and increasing global temperatures. The more tree's that are cut down the slower the process of photosynthesis will occur, this means less oxygen, less oxygen means eventually life on earth might not be sustainable.

Atmospheric Water Vapor

Biosphere:

      The biosphere contain all of earths living things, this includes plants, animals and micro-organisms Deforestation depletes the earth of habitat land for animals. When a multinational company cuts down a forest, the animals that inhabit that part become homeless. Deforestation is a direct cause of some species going extinct. when tree's are cut down with out being replace there is a lot of soil that is exposed, the sunlight drys up the soil and causes it to loose its nutrients. Deforestation also causes the death of micro-organisms which break down soil material and are necessary for plant growth. The Madagascar Dung beetle is now extinct from many years of over foresting and not replenishing the land.

Hydrosphere:

      The hydrosphere contain all of the solid, liquid and gas forms of water on earth. Deforestation causes rapid increase in soil erosion. The hydrosphere is linked to all of the sphere in one way or another. Less tree's mean there will be less perception in an area, this effects the atmosphere because the hydrosphere which consists of water also exists in our atmosphere. If there is little or no precipitation then the land will dry up and become scarce this is linked to the lithosphere. If the land is dry and cannot support plant life, animals will find a new place for their habitats, this is linked to the biosphere.
