Question

question 8
what conditions are necessary for clouds to develop? select two.
particulates
water vapor
rain
nitrogen

Explanation:

Clouds form when water vapor condenses around tiny particles (condensation nuclei). Nitrogen is a major component of air but not directly involved in cloud - formation. Rain is a result of cloud development, not a condition for cloud development. Water vapor is needed to condense, and particulates act as nuclei for condensation.

Answer:

particulates, water vapor
