Q: Which layer of Earth's atmosphere contains the most weather phenomena?

Arab Weather - The troposphere is located in the closest part of the Earth's atmosphere, extending from the Earth's surface to an altitude of approximately 8 to 15 kilometers, and this height varies depending on the geographical location and season. In this layer, most weather phenomena occur, such as clouds, rain, thunderstorms, winds, and changes in temperature.

The troposphere contains about 75-80% of the total mass of the atmosphere, and is the densest layer, containing most of the water vapor and atmospheric gases necessary for the formation of weather phenomena.
