(d) Insolation is the measure of solar radiation energy recieved on a given surface area in a given time. Some of the solar radiation is absorbed and the rest is reflected. Insolation is largest when the surface faces the sun.
Insolation refers to the incoming solar power intercepted by the earth. Sunlight falls almost vertically on the equator, whereas it falls at some angles on the poles. So amount of...
(a) The amount of moisture in atmosphere is related to latitude because the temperature depends upon the latitude and capacity to hold moisture is related to temperature.
(b) Atmospheric temperature of the place depends upon the slope, altitude, latitude, topography, etc. temperature lowers as we go from equator to poles – tropical, subtropical, temperate and arctic.
