What layer of the atmosphere does most whether occur?

Most weather occurs in the troposphere, which is the lowest layer of the Earth's atmosphere. This layer extends from the surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on the location and weather conditions. The troposphere contains the majority of the atmosphere's mass, including water vapor, which is essential for cloud formation and precipitation. As a result, it is where we experience the majority of atmospheric phenomena such as rain, snow, and storms.
