Question

in general, air masses along the southern u.s. tend to be made up of high - pressure air. air closer to the north pole tends to be low pressure air. why does the high pressure air from the south not blow straight to the north?
oa. because the earths rotation twists the winds path to the east.
ob. because the earths surface is heated evenly, canceling out any pressure differences.
oc. because the earths rotation twists the winds path to the west.

Explanation:

The Coriolis effect, caused by the Earth's rotation, deflects moving air (wind). In the Northern Hemisphere, it twists the wind's path to the east. Option B is incorrect as the Earth's surface is not heated evenly. Option C is wrong as the deflection is to the east (in the Northern Hemisphere for the general air movement from south to north discussed here) not west.

Answer:

A. Because the Earth’s rotation twists the wind’s path to the east.
