Question

Assertion :The El Nino, a cold ocean current, flows along the coast of Peru during Christmas. Reason: The presence of the El Nino leads to an increase in sea-surface temperatures and weakening of the trade winds in the region.

• A. Both A and R are true and R explains. A.
• B. Both A and R are true but R does not explain A.
• C. A is true and R is false.
• D. A is false and R is true.

Answer 1

The correct option is D A is false and R is true.

El Nino, meaning "Child Christ'' is a warm ocean current appearing along the Peru coast, generally in December. It normally happens once every 4-5 years though it is not fixed. It replaces the cold Peru Ocean current flowing along the Peru coast in normal years. Under normal conditions, the Peru is a cold water current, while over the Western Pacific ( Indonesia and Eastern Australia ), the ocean current is warm and deep. The appearance of EL Nino reverses the conditions there and develops warm conditions over eastern Pacific ( Peru coast ) and Cold conditions in the Western Pacific. This condition is linked to the Southern Oscillation happening between the Pacific and the Indian Oceans and ultimately leads to weak monsoons in the subcontinent because of the weakening of the monsoonal winds or trade winds.
