Answer 2

Explanation:

Insolation is solar radiation received in the Earth's atmosphere or at its surface. Only approximately 52 per cent of this insolation reaches the earth's surface. The rest is absorbed by water vapour, dust and clouds, or is reflected by the Earth's surface and scattered by particles in the air.
