What is the dependent variable that impacts the amount of solar energy in a location. i really need with question.

Nearness to equator or geographical position

Explanation:

Due to Earth’s spherical shape, the sun rays with high intensity falls on the equator. Therefore if a place is located away from the equator, it will receive low intensity sun rays.  

Countries like India which lie at close proximity to the equator get solar energy in sufficient amount. Such countries are able to harness electricity from solar energy due to its high intensity.

Therefore , Nearness to equator or geographical position is the dependent variable that impacts the amount of solar energy in a location.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
