20 multiple choice 1 point the gulf’s dead zone usually dissipates in:
summer
fall
winter
spring

Explanation:

Question 19

Dead zones (areas with low oxygen) globally have been documented to be over 200. The option 2,000 is too high, 20 and 50 are too low compared to known scientific data on global dead zones.

The Gulf of Mexico's dead zone, caused by nutrient runoff and stratification, typically dissipates in the fall as weather patterns (like storms) mix the water and reduce stratification, increasing oxygen. Summer is when it forms/grows, winter and spring are not the main dissipation times.

Answer:

C. 200+
