Where will the atmospheric pressure be greater - at ground level or at the top of high mountain ?

Explanation

To determine where atmospheric pressure is greater—at ground level or at the top of a high mountain—we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding Atmospheric Pressure**: Atmospheric pressure is the force exerted by the weight of air above a certain point. It is influenced by the height of the air column above that point.

2. **Pressure at Ground Level**: At ground level, there is a significant column of air above us. This means that the pressure exerted by this column of air is relatively high because it includes all the air from the ground up to the top of the atmosphere.
