The correct answer is letter B. Horizontal water movements. Upwelling is a phenomenon that involves the dense's motion because of the wind. It is cooler and makes the water rich in nutrients towards the ocean surface. The warmer air is replaced and nutrient-depleted surface water are also replaced. This makes increase in plankton population and increase in nutrients at the ocean surface. The movement of the water is vertically up.
Acid Rain is the natural cause which causes volcanic eruptions and emissions from vegetation.
<u>Explanation:
</u>
The volcanic eruption is a natural phenomenon that is caused due to the liberation of the lava from the heap of the earth along with the gases. The volcanic eruption results in causing major damages to the vegetation lying above the erupted crater of the volcano.
This results in the immense release of gases such as “carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen chloride, hydrogen fluoride, methane and ammonia” and these gases are major pollutants of the air. When these gases react with water vapour that are present in the atmosphere, they condense in the form of acid rain.
