The statement that accurately describes the relationship between air pressure, air density, and altitude is:

**Denser air exerts more pressure than less dense air.**

To clarify the other statements:

- **As altitude increases, pressure increases.** (Incorrect: As altitude increases, air pressure decreases.)
- **As altitude increases, air density increases.** (Incorrect: As altitude increases, air density decreases.)
- **Air pressure and density are lowest at sea level.** (Incorrect: Air pressure and density are highest at sea level.)

Thus, the correct understanding is that denser air, which is found at lower altitudes, exerts more pressure than the less dense air found at higher altitudes.
