In Plate Tectonic Theory, the lithosphere is broken into tectonic plates, which undergo some large scale motions. The boundary regions between plates are aptly called plate boundaries. Based upon their motions with respect to one another, these plate boundaries are of three kinds: divergent, convergent, and transform.
Answer: The answer is C:
a region of compressed rock located behind a volcanic arc at a convergent continental margin.
explanation:
Typically found in orogenic forelands or in rear-arc position (e.g. on east side of Andes). It's formed during continent-continent collision, and often in passive margin sediments of the subducting plate (and hence can exhume the earlier rift margin that formed the foundation for the passive margin.
Answer:
Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.
Explanation:
The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.
The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.
Answer:
$10
Explanation:
Given data
A phone costs $50
Discount = 20% off
Although we have no set of options to choose from, here is the Answer
Let us compute the discounted amount
= 20/100*50
=0.2*50
=$10
Hence the amount that was discounted is $10
