Answer:
a) divergent boundaries by submarine eruptions and intrusions of basaltic magma
Explanation:
Divergent boundary is where tectonic plate move apart from each other. Divergent boundary is mostly prevalent in the oceanic crust. The opposing plate tends to move apart from each other.
On the oceanic crust plates move apart from each other causing an upwelling of magma from the aesthenosphere. This magmatic material is introduced through the oceanic ridges. As the magma are introduce the opposing plates separates further . The basaltic magma introduced through the oceanic ridges forms the new oceanic crust. As we move away from the oceanic ridge the rocks gets older . The oceanic ridge where the basaltic magma erupt depict the youngest rocks.
Answer:
9.59
Explanation:
((X1+X2)^2)+((Y1+Y2)^2)
And the square root the answer
Deposition has to do with deltas because when deposition such as water wind or ice moves the sediments and deposits them at the end of a river lake or ocean a delta is formed
According to MacArthur and Wilson's theory of island biogeography, the following is correct:
a. The number of species decreases with island isolation.
