How Does Erosion Affect the Earth?

Sep 28 2018Most erosion – the breakdown and movement of soil and rock – in the world is caused by wind water and gravity The effect of soil erosion on agricultural land is bidirectional Humans can be a cause by exposing soil to natural forces but wind and water can independently cause erosion Get price

Negative Effects of Coal Mining

The negative effects of coal mining cannot be disputed Destruction of Landscapes and Habitats Strip mining also known as surface mining involves the stripping away of earth and rocks to reach the coal underneath If a mountain happens to be standing in the way of a coal seam within it will be blasted or levelled - effectively leaving a scarred landscape and disturbing ecosystems and wildlife habitat Get price

Layers Of The Earth What Lies Beneath Earth's Crust

Jan 16 2016Earth's Crust Below the crust is a solid relatively cooler portion of the upper mantle that is combined with the crust to make the lithosphere layer The lithosphere is physically distinct from the below-lying layers due to its cool temperatures and typically extends 70-100 km in depth Get price

Where does coal come from?

Aug 04 2009But coal also has a dark side — its high carbon content means it emits more carbon dioxide than other fossil fuels giving it a disproportionately big carbon footprint Add in the ecological costs of mountaintop removal fly-ash storage and coal transportation and the black lump loses even more of its luster Get price

What effect does removing oil from the earth have on the

This explains its high energy content Given time organic sedimentary rock breaks up to form fertile soil There is a finite amount of matter in the earth- oil is in the process of becoming a life source for new plants When the earth's oil is burnt the net potential for life on earth decreases The net result is an increase in death Get price
