Which of the following processes has directly caused ocean currents to change over earth's history? a. ice-albedo feedback b. continental drift c. axial precession d. volcanic activity

Option (B)

Explanation:

The continental drift is defined as the shifting of the continents over the large water body with respect to the poles. These continents moved from one place to another across the line of different latitudes and longitudes, experiencing various types of climatic conditions, due to which the ocean water currents has been significantly affected. This presence and continuous motion of continents affects the direction of the ocean currents that moves from the equatorial to the polar region.

Thus, over the earth's geological history, the ocean currents are undergoing changes due to the continental drifting.

Hence, the correct answer is option (B).

A. the seasoning of enslaved Africans

Explanation:

The term 'Seasoning' Refers to a disease outbreak that enslaved Africans gt after they're being put in a different environment.

Generally, African slaves were kept in a terrible condition, with very little hygiene, high humidity, and not enough sunlight.  This caused many African slaves in Jamaica obtain various type of Tropical diseases, specifically Malaria  (which is caused by mosquitoes bite).

The slave owners did not see any merit in treating the slaves, so most of the ones that infected were just left there without any medication. This explains the really high mortality rate.
