The main reason why Earth is warmer at the equator than at the North and South Poles are thats where the sunlight shines at a lot of times. The sunlight never really shines directly at the North and South Poles like it does with the equator.
I think the one that can impact the climate of an area based on its geographical relief would be : B. Elevation
Mountain exist in a higher elevation lands and ocean exist on the lower elevation. The areas in higher elevation tend to have lower temperature compared to those in lower elevation
hope this helps
The answer would be D. One of the main reasons for Antarctica's dryness is its lack of precipitation.
The more direct sunlight an area receives the warmer the temperatures will be, while the indirect sun rays on a certain area cause cooler/colder temperatures.
