Question

which is a possible consequence of global warming?
o a decrease in temperature, causing earlier frosts
o an increase in the amount of coral reefs
o a decrease in temperature, causing shorter growing seasons
o an increase in the number of heat waves, causing droughts

Explanation:

Step1: Analyze option A

Global warming causes an increase in temperature, not a decrease. So option A is wrong.

Step2: Analyze option B

Global warming leads to coral bleaching (damage to coral reefs) due to rising ocean temperatures, not an increase in coral reefs. So option B is wrong.

Step3: Analyze option C

Global warming causes an increase in temperature. Longer growing seasons (in some regions) due to warmer temperatures are more likely than shorter ones. So option C is wrong.

Step4: Analyze option D

Global warming can lead to more extreme weather events. Heat waves can cause evaporation of soil moisture, leading to droughts. So option D is correct.

Answer:

D. an increase in the number of heat waves, causing droughts.
