What do mine operators do to fix land that has been strip mined?
To strip mine, the mining operation requires the removal of the overburden. That's all the stuff on top of the material that the mining company wants to extract. With the overburden removed, and the material removed, overburden is replaced and suitable surface cover is re-established. Some thought and planning are included in coutouring the surface to "match" the area around it. The mining company might plant trees, shrubs or just sow grasses on the land, according to the nature of the surrounding vegetation, and also their agreement with the regulators who will inspect the finished operation.
What are the practical applications of environmental geology?
There are many practical applications of environmental geology. Some applications include studying changes in the Earth's surface and managing natural hazards.
What is groundwater and why is groundwater pollution the most likely environmental danger of landfills?
Groundwater, simply, is the water beneath the surface of the ground.
What is the impact on silver mining of the environment?
Very little. Most silver is mined in deep shafts below the surface and refined in smelters which do not have chemical residues. The tailings can be slightly radioactive, but overall low environmental impact
How can geologists infer from sedimentary rocks what the surface conditions of Earth's past were like?
The inferences are made primarily from the fossils contained within the rock. The surface conditions drive the evolution of organisms as they adapt to those conditions. The type of organisms found in the fossil record therefore indicate the climatic and environmental conditions that existed at the time of their fossilization.
Can coal be found on the surface?
Coal can be found in certain locations where it is exposed at the surface via erosion of the overburden. Most often, it is not.
What surface mining is sometimes known as?
Sometimes called "strip" mining- soil and overburden is stripped away, exposing the coal.

How do you minimize the surface area of cuboid?
Make it infinitesimally small.
How easy is it to gain access to coal?
It depends on the depth from surface of the deposit. There are places where coal is naturally exposed at the surface or covered with very little overburden. There are also places where coal is found at relatively great depth.
Why the stomata on undersurface of leaf?
To minimize the rate of transpiration from leaf surface

What is the advantage of using application virtualization?
It lets you minimize the attack surface relating to the application.
What relationship between surface area and volume must organisms achieve to ensure efficient delivery of nutrients?
maximize surface area and minimize volume
