In he troposphere, the bottom layer of Earth's air, the temperature changes from 17°C to -51°C, getting cl

oser to the Earth's surface. The troposphere is where most weather events occur, such as clouds, rain, and storms. The temperature decreases with altitude in the troposphere, due to the decreasing pressure and density of the air. This is known as the lapse rate, and is approximately 6.5°C per kilometer of altitude. The temperature changes in the troposphere play a crucial role in the formation of weather patterns and the distribution of heat around the Earth.
