Answer:
on the first day of fall, change.
The theory
of a land bridge between South America and Africa as an explanation for similar
fossils on the two continents is not supported today because there are
no remnants of the bridge in the Atlantic Ocean.
<span>A </span>land
bridge, in biogeography<span>, is an </span>isthmus<span> or wider land connection between otherwise separate areas, over which
</span>animals<span> <span>and </span></span>plants<span> <span>are able to cross and </span></span>colonize<span> <span>new lands. A land bridge can be created by </span></span>marine regression<span>, in which </span>sea
levels<span> <span>fall, exposing shallow, previously submerged sections of </span></span>continental shelf<span>; or when new land is created by </span>plate tectonics<span>; or occasionally when the sea floor rises due to </span>post-glacial rebound<span> <span>after an </span></span>ice
age.
The correct answer between all
the choices given is the first choice or letter A. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and
if you would like, feel free to ask another question.
The speed and violence of the tectonic processes are different.
Divergence is slower and somewhat gentler, and there is less restricting pressure to oppose the upwelling magma (Water may be heavy, but it IS fluid.) The fluidity and cold temperature of the ocean absorb and dissipate the violence of forcing magma out of the mantle and the encounter between great heat and cold waters.
Convergence may combine tectonic movement from multiple vectors, different types of plates may force an oceanic plate under a continental plate and the collision speed will determine the subduction angle and depth. The ejection of material from great depth, through an overriding solid plate, requires great force and pressure. Where hot material encounters underground waters, resultant steam may be superheated and compressed.
Note, however, that volcanic eruptions resulting from deep underwater hot spots may be the most violent of all such events, belying the question’s premise.
Hope this helps :)
