Test: Climate- 1 - Question 2

Which one of the following warm ocean currents replaces the Peruvian cold current?

Detailed Solution for Test: Climate- 1 - Question 2

Warm Ocean Currents and the Replacement of the Peruvian Cold Current:
The Peruvian cold current, also known as the Humboldt Current, is a cold ocean current that flows northward along the western coast of South America. It is responsible for the upwelling of nutrient-rich waters, which supports a diverse marine ecosystem and contributes to the productivity of the region. However, at times, this cold current is replaced by a warm ocean current.
The warm ocean current that replaces the Peruvian cold current is known as El Nino. El Nino is a climatic phenomenon characterized by the warming of sea surface temperatures in the equatorial Pacific Ocean. This warming causes a disruption in the normal atmospheric circulation patterns, leading to changes in weather patterns across the globe.
Key Points:
- The warm ocean current that replaces the Peruvian cold current is El Nino.
- El Nino is a climatic phenomenon characterized by the warming of sea surface temperatures in the equatorial Pacific Ocean.
- El Nino causes a disruption in normal atmospheric circulation patterns, leading to changes in weather patterns globally.
- During El Nino events, the Peruvian cold current weakens or reverses, allowing warm water to flow along the western coast of South America.
- The warm water brought by El Nino has significant impacts on marine ecosystems, fisheries, and weather patterns in the affected regions.
Therefore, the correct answer is B: El Nino.

  3. Rainy season: The rainy season is a period of the year when there is a significant amount of rainfall. This season is typically associated with regions that experience monsoon climates or tropical climates. The specific months of the rainy season can vary depending on the location. The rainy season is included in the division of seasons based on atmospheric conditions.

  4. Spring season: Spring is a season that marks the transition from winter to summer. It is characterized by milder temperatures, increasing daylight, and the blossoming of flowers and trees. Spring is typically associated with the months of March, April, and May in the Northern Hemisphere and September, October, and November in the Southern Hemisphere.
