Which of the following is a cold ocean current?
Options:
A .  Canary current
B .  Oyashio current
C .  Humboldt current
D .  Brazil current
Answer: Option C
Answer: (c)
The Humboldt Current, also known as the Peru Current, is a cold, low-salinity ocean current that flows north-westward along the west coast of South America from the southern tip of Chile to northern Peru.
It is an eastern boundary current flowing in the direction of the equator and can extend 1,000 kilometres offshore. The Humboldt Current Large Marine Ecosystem (LME), named after the Prussian naturalist Alexander von Humboldt, is one of the major upwelling systems of the world, supporting an extraordinary abundance of marine life.
Upwelling occurs off Peru year-round but off Chile only during the spring and summer, because of the displacement of the subtropical centre of high pressure during the summer.
