Answer:
there is not enough data for the question you're trying to ask, because the word "data" in your statement is a variable, and can have more than one meaning.
Answer:
The height of a place above the mean sea level is called altitude. Temperature of a place and its altitude are interrelated. The higher the altitude the lower is the temperature. Temperature decreases with an increase in the height of a place above the sea level.
Air is cooler at higher altitudes than in the earth's surface. The main reason for the decrease in temperature with height is that the atmosphere is heated from below more by terrestrial radiation than the incoming radiation from the sun.
Air on the surface of the earth is denser and contains more of carbon dioxide and other gases. These gases trap the sun's heat and contribute to global warming.
The rate of decrease of temperature with height is about 6°C for every 1km ascent. This means on climbing ever 166m there would be a 1°C fall in temperature. This is known as Normal Lapse Rate. It is usually more in summer than in winter. This explains why it is cooler at the top of the mountains than at the plains.That is why the hilly resorts are more pleasant than at the plains
