Question 1

True or false: El Niño was named after the Spanish word for 'the child' because it is a small-scale event.

Accepted Answer

False. El Niño means 'the little boy' in Spanish, referring to the Christ child due to its appearance near Christmas, not its size.

Question 2

True or false: El Niño occurs every year in the month of December.

Accepted Answer

False. El Niño events happen irregularly every 2 to 7 years, not annually, and can start in various months.

Question 3

True or false: El Niño results from weakening trade winds that allow warm water to shift eastward.

Accepted Answer

True. Weakened Pacific trade winds reduce upwelling and allow warm surface water to pool in the central and eastern Pacific, triggering El Niño.

Question 4

True or false: El Niño typically causes drier-than-average conditions in Indonesia and Australia.

Accepted Answer

True. El Niño shifts rainfall away from the western Pacific, leading to drought in Indonesia and eastern Australia.

Question 5

True or false: El Niño always leads to colder winters in the northeastern United States.

Accepted Answer

False. El Niño usually brings milder winters to the northern US by shifting the jet stream, not colder ones.

Question 6

True or false: El Niño is primarily caused by human-induced climate change.

Accepted Answer

False. El Niño is a natural part of the ENSO cycle and has occurred for centuries, long before human-caused climate change.

Question 7

True or false: El Niño events have been recorded in historical accounts from the 1500s.

Accepted Answer

True. Spanish explorers and Peruvian fishermen documented El Niño's warm currents near Christmas as early as the 16th century.

Question 8

True or false: El Niño can weaken the Atlantic hurricane season by increasing wind shear.

Accepted Answer

True. El Niño enhances vertical wind shear over the Atlantic, which disrupts hurricane formation and reduces the number of storms.
