Question

air pressure, a measure of the force with which air molecules push down on earth’s surface, gr influences weather. air molecules (the atmosphere) surround the earth, and the pull of gravity g air molecules weight. at the surface, air pressure is greatest because of the weight of all the air n from the atmosphere pushing down. as altitude increases, air pressure decreases because there ar gas molecules above you pushing downward. differences in air pressure are created by the unequal heating of earth’s surface. warm, less dense air rises creating areas of low pressure (counterclockwise), while cool, denser air sinks creating areas of high pressure (clockwise). this circular movement of rising warm air and sinking cool air is known as the convection current and is how the majority of the thermal energy in the atmosphere moves. differences in air pressure create moving air, which is called wind. winds usually travel from areas high pressure to areas of low pressure and the greater the difference between the pressures, the stro the winds will be. what causes wind to form? the rotation of the earth differences in air pressure the amount of moisture in the air the position of the sun

Explanation:

The text states "Differences in air pressure create moving air, which is called wind." So the cause of wind formation is differences in air pressure. The other options (Earth's rotation, moisture in air, Sun's position) are not mentioned as the cause of wind in the given text.

Answer:

B. Differences in air pressure
