Thunder occurs in the troposphere, the lowest and most turbulent layer of the atmosphere. This is the only region containing enough moisture and convective energy to form cumulonimbus clouds, which are the source of lightning and thunder. As electrical charges build up within these massive clouds, a sudden discharge heats the air, creating the explosive sound waves. ANSWER: (A) Troposphere
Share
All significant weather events, including thunder and lightning, are confined to the troposphere. This layer is characterized by high concentrations of water vapor and unstable air masses that are necessary for the development of massive storm clouds. When warm air rises rapidly, it creates friction between ice particles and water droplets, generating powerful electrical charges. The resulting lightning strike superheats the surrounding air to incredible temperatures, causing it to expand almost instantly. This rapid expansion creates a sonic shockwave known as thunder. Because the layers above lack sufficient moisture, these dramatic electrical storms cannot form anywhere else.
