Earth's Geography and Climate Practice Test

Strengthened trade winds increase upwelling in the eastern Pacific, cooling waters and boosting nutrient availability, causing larger fish harvests.

Weakened trade winds reduce upwelling in the eastern Pacific, warming surface waters and lowering nutrient supply, which can reduce fisheries productivity.

Thermohaline circulation stops within days, freezing coastal waters and increasing sea ice, which enhances upwelling and nutrients.

Polar jet stream shifts permanently to the equator, creating constant midlatitude cyclones and cooling tropical sea-surface temperatures.
