Question

Investigate each statement and select the one that best describes why southwest South America has a dry climate. (1 point)
• There is a cold ocean current on the west coast of South America.
• The northeast trade winds blow onto the west coast of South America.
• Southwest South America is in the intertropical convergence zone.
• The Gulf Stream produces a dry climate in southwest South America.

Answer 1

The statement that best describes why southwest South America has a dry climate is:

• There is a cold ocean current on the west coast of South America.

This refers to the Humboldt Current, which is a cold ocean current that flows northward along the west coast of South America. The presence of this cold current contributes to the aridity of the region by creating cooler temperatures and inhibiting moisture-laden air from reaching the land, thus leading to dry conditions.
