a. there is a concentration of magma rising at the equator
b. heat roses from the southern pole and is the warmest in the middle of the globe
c. the equator receives more direct and intense sunlight, warming the water
d. the volcanic activity at the equator heats up the water
The correct answer is c. The equator receives more direct and intense sunlight than any other part of the Earth, which leads to higher temperatures and warm water. This causes ocean currents to begin at the equator. The other options (a, b, and d) are not accurate explanations for why ocean currents begin at the equator.
The correct answer is c. The equator receives more direct and intense sunlight, warming the water. Ocean currents, including warm ocean currents, are primarily driven by the movement of heat energy within the Earth's atmosphere and oceans. The equator receives more direct sunlight compared to other regions of the Earth, which leads to intense heating of the water. As the water warms, it expands and becomes less dense. This causes it to rise and flow towards the poles, creating warm ocean currents.
