El Nino is a climate pattern that describes the unusual warming of surface waters in which ocean?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Pacific Ocean.
El Niño is a climate phenomenon characterized by the unusual warming of surface waters in the Pacific Ocean, specifically in the central and eastern parts. This warming event occurs periodically, typically every 2 to 7 years, and can last for several months. El Niño disrupts normal weather patterns, leading to significant global climatic changes.
The phenomenon is part of a larger climatic system called the El Niño-Southern Oscillation (ENSO), which includes both El Niño (the warming phase) and La Niña (the cooling phase). When El Niño occurs, it can result in severe weather events, such as heavy rains, droughts, and altered storm patterns, affecting various regions around the world.
For example, El Niño can cause droughts in Australia and Southeast Asia, while leading to wetter-than-usual conditions on the west coast of South America and parts of the United States. Understanding El Niño is crucial for predicting weather and managing agricultural and water resources.
