  E. None of the above

Please explain................................

A geostrophic wind is a balance between:

A. Gravity and the pressure gradient force

B. Friction and gravity

C. Coriolis and the pressure gradient force

D. Friction and the pressure gradient force

E. Centrifugal, pressure gradient force and Coriolis

Please explain...........................

Explanation / Answer

1] Option D is correct.

When the barometric pressure falls, warm air rises, and cools as it goes higher into the atmosphere.

2] Option C is corrrect.

A geostropic wind balanced by the Coriolis and Pressure Gradient forces. An air parcel initially at rest will move from high pressure to low pressure because of the pressure gradient force.
