A mine entrance is at ground level. A measuring instrument records atmospheric pressure at the entrance and at a lower level in the mine on the same day.
| Position | Atmospheric pressure |
|---|---|
| Mine entrance | 100.8 kPa |
| A lower level in the mine | 106.1 kPa |
Calculate the increase in atmospheric pressure between the two positions. Explain why the atmospheric pressure is greater at the lower position.
