Question

question 5
the ____ can change the direction air moves, but not its speed.
a pgf = pressure gradient force
b cf = coriolis force
c fr = frictional force
d gr = gravitational force

question 6
the strength of the ____ is visualized on a surface map by isobars.
a pgf = pressure gradient force
b cf = coriolis force
c fr = frictional force
d gr = gravitational force

Explanation:

Question 5

The Coriolis Force (CF) acts perpendicular to the direction of air motion. It changes the direction of air movement but does not affect its speed. The Pressure Gradient Force (PGF) affects both speed and direction. Frictional Force (FR) can change speed and direction. Gravitational Force (GR) mainly acts vertically and is not the force described here.

Isobars are lines of equal pressure. The Pressure Gradient Force (PGF) is related to the change in pressure over distance. The spacing and pattern of isobars on a surface map show the strength of the PGF. The Coriolis Force (CF) is related to Earth's rotation, Frictional Force (FR) is about surface - air interaction, and Gravitational Force (GR) is not visualized by isobars in this context.

Answer:

B. CF = Coriolis Force
