Question

which characteristic describes the troposphere? contains the ozone layer has the highest air pressure spans 12 - 50 km above earth is a good place for planes to fly

Explanation:

• The ozone layer is in the stratosphere.
• The troposphere is the lowest layer of the atmosphere, so it has the highest air pressure due to the weight of the air above it.
• The troposphere spans about 8 - 20 km (not 12 - 50 km) above Earth.
• Planes usually fly in the stratosphere (for a smoother flight as there is less turbulence compared to the troposphere).

Answer:

has the highest air pressure
