The wind blows in response to
(a) frictional drag.
(b) Earth’s rotation.
(c) pressure differences.
(d) moisture differences.
The correct option for the statement “The wind blows in response to”.
Answer to Problem 7RAT
he correct option for the statement “The wind blows in response to” is option (c).
Explanation of Solution
The warm air has a lesser density as compared to the cold air. The density of air decreases with the increase in temperature. The lower-density air rises and vacant the place, then the higher density cold air takes the vacant place continuously. The continuous process provides convection current and thermal circulation to the atmosphere, and this stir of atmosphere results in wind.
Air travels whenever there is a difference in the pressure between the two positions. The pressure depends on temperature and the variation in temperature results in the difference in the pressure from one place to another place, and due to this wind blows.
Conclusion:
Therefore, the correct option for the statement “The wind blows in response to” is option (c).
