runoff and evaporation transpiration and precipitation precipitation and runoff transpiration and evaporation
I gave my students this multiple choice question: During an ice age, enormous ice sheets called glaciers increase in size on Earth's surface, resulting in decreased ocean depths. Due to global cooling, the water cycle is disrupted between which two stages to cause an increase in glacier size?

Only one answer is correct among these 4 choices:
- runoff and evaporation
- transpiration and precipitation
- precipitation and runoff
- transpiration and evaporation

Could you tell me which one is correct?

precipitation and runoff
