Question

structure and composition of the atmosphere quiz complete 4 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:

To determine the correct characteristic of the troposphere:

• The ozone layer is in the stratosphere, so "contains the ozone layer" is incorrect.
• The troposphere has the highest air pressure among atmospheric layers (air pressure decreases with altitude), so this is correct.
• The stratosphere spans around 12 - 50 km, not the troposphere (troposphere is ~0 - 12 km), so "spans 12 - 50 km above Earth" is incorrect.
• Planes typically fly in the stratosphere (for commercial jets) or lower troposphere, but the troposphere isn't the "good place" in the way the option implies (stratosphere is better for jet travel due to stable conditions), so "is a good place for planes to fly" is incorrect.

Answer:

The option "has the highest air pressure" (the second option from the top)
