The Lower Solar Angles Characteristic of High Latitude Locations Leads

Multiple Choice

The lower solar angles characteristic of high latitude locations leads to lower levels of insolation because:

A) the solar radiation has further to travel and so looses its strength
B) the solar radiation is spread over a larger unit area
C) the solar radiation is spread over a smaller unit area
D) the solar radiation must travel through more volume of atmosphere and so more radiation is reflected back to space
