Compared to that of a plane on the ground, earth’s gravitational pull on a plane 7 miles above earth is approximately a) zero. b) the same. c) half as much. d) twice as much.

B) the same

Explanation:

    The altitude of the atmosphere is about 1,000 km (622 miles), yet 80% of the fluid mass is 5 km (3.5 miles) above the earth's surface.

     The gravity on the surface is influenced by the pressure that the air exerts due to its weight, this can happen in different ways depending on the point and time and many other circumstances.
