Question

Quizplus · Accepted Answer

Dew forms when warm, moist air comes in contact with cool surfaces. This is because cool surfaces cause the air to cool down, which reduces its ability to hold moisture, causing the moisture to condense into droplets on the surface.

Option B is incorrect because rain or fog is more likely to occur when warm, moist air is cooled, causing the moisture to condense and form clouds or precipitation.

Option C is also incorrect because warm air can hold more moisture than cold air. As the temperature increases, so does the air's ability to hold moisture.

Option D is incorrect because fog occurs when cool, moist air moves over warmer land or water surfaces, causing the air to become saturated and form fog.
