Question

20
insolation means _.
the material that makes a building retain warm
or cool air.
incoming solar revolution
intermediate solar radiation
incoming solar radiation

Explanation:

Insolation is a term in geography (a sub - field of natural science). It specifically refers to the amount of solar radiation that reaches a particular area. The other options are incorrect. The material that makes a building retain warm or cool air is related to insulation (a different concept). "Incoming Solar Revolution" is a misnomer as it combines two unrelated terms (solar and revolution). "Intermediate Solar Radiation" is not the standard definition of insolation.

Answer:

Incoming Solar Radiation
