Yes, the troposphere is the lowest layer of the Earth's atmosphere, and it is responsible for weather changes. This is because the troposphere is where all of the weather phenomena occur, such as clouds, rain, snow, and storms. The troposphere is also where the air that we breathe is located, and it is constantly changing due to the movement of air masses and the heating and cooling of the Earth's surface. These changes in the troposphere can lead to changes in weather conditions, such as changes in temperature, humidity, and precipitation.
