Which statement is correct for understanding the difference between altitude and relief?

Correct answer: Altitude affects temperature and relief can change wind rainfall path

The direct answer is A: altitude affects temperature, and relief can change the path of winds and rainfall. Altitude means the height of a place above sea level. As altitude generally increases, temperature decreases, so high places are often cooler. Relief means the shape and arrangement of landforms such as mountains, plateaus, valleys, and slopes. Relief can block, divert, or lift moving air. When moist air rises along a mountain, it may cool and produce rain on one side, while the other side may be drier. Option A is correct because it separates the main effects of the two controls. Option B is wrong because neither altitude nor relief explains language. Option C is wrong because relief can strongly affect wind movement and rainfall and can also influence local temperature. Option D is wrong because altitude is height, not an ocean current. Memory cue: altitude is height; relief is landform shape and its barrier or lifting effect.
