all of these are required for clouds to form except ...
○ cooler air mass
○ tiny particles suspended in the air
○ high winds

clear my selection

Explanation:

Question 9

A wind vane measures wind direction, a thermometer measures temperature, an anemometer measures wind speed, while a barometer is specifically used to measure atmospheric pressure. So Obi should use a barometer.

For cloud formation, moist air (to provide water vapor), tiny particles (condensation nuclei), and a cooler air mass (to cool the moist air and cause condensation) are required. High winds are not a necessary condition for cloud formation.

Answer:

B. barometer
