Question

1. the greatest atmospheric pressure exists in which layer? type a response

Explanation:

Atmospheric pressure is the force exerted by the weight of air molecules. The troposphere is the lowest layer of the atmosphere, closest to the Earth's surface. As we move up in the atmosphere, the number of air molecules decreases, so pressure decreases with altitude. Since the troposphere is the lowest layer, it has the highest density of air molecules, resulting in the greatest atmospheric pressure.

Answer:

The greatest atmospheric pressure exists in the troposphere.
