Answer:
The atmosphere is heated or cooled by the following processes:
(1) Partial absorption of solar radiation by the atmosphere
(2) Conduction
(3) Terrestrial radiation
(4) Convection and advection
(5) Latent heat of condensation
(6) Expansion and compression of the air.
<u>Biodiversity</u> is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.
Answer: E. Is produced by "fracking", which uses high-pressure water and chemicals to make new "fractures" in the shale that allow the gas to escape to wells.
Explanation:
The Marcellus is a large area in the eastern part of the USA. Natural gas is extracted here through fracking or hydraulic fracturing. This is a process in which water at high pressure is injected into a drilled holes thereby creating holes in the rocks housing the gas and petroleum and sending them into a well
.
While fracking provides natural gas, a cleaner source of energy than coal, fracking has some environmental costs such as ground water contamination and the risk of setting off earthquakes.

Layers that are less dense, such as the crust<span>, float on layers that are denser, such as the mantle. Both </span>oceanic crust and continental crust<span> are less dense than the mantle, but </span>oceanic crust<span> is denser than </span>continental crust<span>. This is partly why the </span>continents <span>are at a higher elevation than the </span>ocean<span> floor.</span>
