Which layer of the atmosphere is known for its weather phenomena?

The troposphere is the lowest layer of the atmosphere and is where nearly all weather phenomena occur. This layer extends from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on geographic location and weather conditions. Weather events such as clouds, rain, snow, and storms are generated in the troposphere due to the presence of water vapor and the conditions created by temperature changes.

In contrast, the stratosphere, which lies above the troposphere, is known for its relatively stable air that contains the ozone layer, but it does not experience the turbulent weather patterns seen below. The thermosphere is characterized by extremely high temperatures and is where the ionosphere exists, affecting radio communications but not playing a role in weather systems. The mesosphere is located above the stratosphere and is where meteors burn up upon entering the atmosphere, but it also lacks the conditions necessary for weather phenomena. Thus, the troposphere is uniquely suited to support all forms of weather due to its proximity to the Earth's surface and the right amounts of moisture and temperature variation.
