Answer:
A≈907.92in²
Explanation:
A=πr2=π·172≈907.92028in² hope this helps ;)
The answer is the option B) hydrosphere.The prefix hydro means water and
so the name hydrosphere is the term used to refer to all the bodies of
water in the Earth, including oceans, groundwater and
glaciers.Atmosphere refers to the gas layer, biosphere to the regions
where there is life and geosphere refers to all the layers in Earth.
Answer:
c) No UV light until spring
Explanation:
According to research, chlorofluorocarbons also known as CFCs, are chemicals that are mainly responsible for the destruction of the ozone gas.
<em><u>This is all due to the interaction of different factors, and not only because of the presence of UV. </u></em>
In Antarctica, the ozone levels become significantly reduced during spring because of these chemicals that contain chlorine, producing a hole where cool air becomes trapped. This air produces clouds that are responsible of the release of chlorine from the CFCs, an extremely important process of the formation of an ozone hole. The more clouds there are, the more gases are released, and the worse the ozone hole will be in spring.
Because the sun rises and becomes more intense during spring, it degrades these gases and releases the free radicals of chlorine, which are highly detrimental for the ozone layer as they destroy numerous molecules of ozone. By the beginning of summer, there is a higher amount of ozone that comes from other areas which help fill the ozone hole.
Answer:
Oceanic Lithosphere
Explanatation
Oceanic lithosphere is more dense (compacted by immense pressure from oceans) and the continental lithosphere is less dense (lack of pressure from anything above it). When the two collide, the continental lithosphere will essentially float on top of subterranean magma while the oceanic lithosphere, being the denser of the two, will slip beneath the continental lithosphere and dive into the magma chamber.
