How does erosion slow down the green house effect?
Erosion reduces top soil. Top soil fosters plant growth, which acts as a carbon sink. So erosion should actually increase the greenhouse effect rather than slow it down. It is possible mineral salts and lighter aeolian depositions on eroded landscapes could increase earth's albedo, reflecting more light back into space, which could have a slight cooling effect.

What type of soil holds water best top soil or potting soil?
Asked in Ecosystems
Would using fire to eliminate most plants in the area have a positive effect on that area?
Unless the are was quickly replanted, the effect would be negative as the loss of plant cover makes the ground more subject to erosion and loss of top soil. If you replant with a uniform plant cover you may also have a negative effect in that variety seems to support a stronger ecosystem. For example, replacing a natural forest with a tree plantation reduces the available habitat for many animals that lived in the original forest

What are the differences between top soil and sub soil?
Top soil refers to the top layer of soil that has a mix of vegetative matter and soil in it. The thickness of this layer varies from location to location. If you cut through sod with a spade and create a hole about 12" deep, you can see where the top soil turns into sub soil, which is a denser, lighter layer of soil. Generally, the top soil is darker because of the amount of decomposed plant matter in it - and the subsoil is lighter because it is mostly the mineral content: silt, clay, and sand.
