The table shows atmospheric pressure at three heights on the same day.
| Height above sea level in m\mathrm{m}m | Pressure in kPa\mathrm{kPa}kPa |
|---|---|
| 0 | 100 |
| 1000 | 89 |
| 2000 | 79 |
Compare the two height intervals. Which statement correctly describes the pressure decrease from 1000 m to 2000 m compared with the decrease from sea level to 1000 m?
The decrease in kilopascals is smaller, and the percentage decrease is smaller.
The decrease in kilopascals is larger, but the percentage decrease is smaller.
The decrease in kilopascals is smaller, but the percentage decrease is larger.
The decrease in kilopascals is larger, and the percentage decrease is larger.
