Answer:
B. The equator is susceptible to extreme storms so the thermocline changes significantly throughout the year.
Explanation:
Storms occurs on that locations where there is high temperature and high temperature is only present at the equator due to direct sunlight. So we can say that maximum storms comes at and near the regions of equator. The oceans present near the equator have a warm layer known as thermocline from where water is evaporated and the intensity of storms are also increases.

People refer to "Darwin's finches" from time to time as a symbol of evolution in the Galapagos Islands, but the father of evolutionary theory actually dropped the ball on those birds, collecting better details on mockingbirds, tortoises and other species.
Charles Darwin's observations, notes and collected organisms from the Galapagos Islands during his 5-year voyage on the Beagle resulted in his theory of evolution by natural selection, one of the best substantiated theories in the history of science.
He collected several finch species, including the warbler finch, sharp-beaked finch, ground finch, small tree finch, large tree finch, common cactus finch and large ground finch.
