Let X% of sunlight reach the Earth's surface while Y% is trapped by greenhouse gases. Find the value of (X - Y).
- 100
- 0
- 50
- 25
Correct answer: 50
Solution
According to the standard atmospheric model, roughly 51% of solar radiation reaches Earth's surface (X = 51) while about 1% is trapped by greenhouse gases (Y = 1), giving X - Y = 50.
