Why is altitude called a climatic control?

Correct answer: Because temperature changes with altitude

Direct answer: A, temperature changes with altitude. Altitude means the height of a place above sea level. As altitude increases in the troposphere, air pressure generally decreases and the air is usually cooler, so highland places often have lower temperatures than nearby lowlands. This effect helps shape local climate, not merely a place’s physical description. Option A is correct because temperature is an important climatic element and its relationship with height affects living conditions, clothing, crops and settlement. B is unrelated: altitude does not indicate language. C is not a definition; altitude is a measurement of height, not a city name. D is false because air pressure and temperature vary with height, showing that altitude is connected with atmospheric conditions. Memory cue: climb higher, and the air is generally cooler, though actual weather also depends on other controls.
