Question

what is insolation?○ heat trapped by greenhouse gases○ energy reflected back to space○ the insulation layer in earths atmosphere○ solar radiation reaching earths surfacequestion 2why does water play such an important role in earths heat budget?○ water covers most of earths surface area○ water reflects more radiation than land○ water absorbs only ultraviolet radiation○ water has the highest specific heat of common substances

Explanation:

For the first question: Insolation is defined as the incoming solar radiation that reaches the Earth's surface.
For the second question: Water's high specific heat means it can absorb and store large amounts of heat without a large temperature change, which is key to regulating Earth's heat budget.

Answer:

1. D. Solar radiation reaching Earth's surface
2. D. Water has the highest specific heat of common substances
