The subject of science is very broad. With that being said, I think there is no official regulatory board that decides the branches of science. Scientific developments are products of joined efforts of different scientists. These scientists could rebuke another's work provided there is evidence. As long as the theory is generally accepted by the scientists and no one rebukes it effectively, then it is a generally accepted fact and everyone adapts it.
Hence, the answer is B.
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.
