Why does atmospheric pressure at a height of about 6 km decrease to...

Why does atmospheric pressure at a height of about 6 km decrease to nearly half of its value at sea level, despite the atmosphere's height being more than 100 km?

Options

  1. ABecause air density decreases with increasing altitude, leading to lower atmospheric pressure.
  2. BDue to the presence of ozone layer, which reduces pressure in the upper atmosphere.
  3. CIt is a result of the Earth's magnetic field affecting pressure distribution.
  4. DAtmospheric pressure remains constant throughout the atmosphere, and the given statement is incorrect.

Correct answer

A. Because air density decreases with increasing altitude, leading to lower atmospheric pressure.

Step-by-step solution

Correct Option is : (A)
Because air density decreases with increasing altitude, leading to lower atmospheric pressure.
