Question

What is the pressure gradient?

• A. The rate of change of pressure with respect to distance.
• B. The rate of change of pressure with respect to altitude.
• C. The rate of change of pressure with respect to temperature.
• D. The rate of change of pressure with respect to friction.

Answer 1

The correct option is A The rate of change of pressure with respect to distance.

The change in pressure with horizontal distance is termed as pressure gradient. Winds blow faster when pressure gradient is steep.The pressure gradient is the re pressure rises or falls. The gradient is steep when pressure changes in a short distance and mild when pressure changes long distances. The pressure gradient is shown by isobars. When isobars are closer, the pressure gradient is steep and viceversa.
