Question

One way of classifying types of clouds is by the way in which they are formed. Two categories are cumulus and stratus. Cumulus clouds are formed when areas of moist air are warmed and rise quickly. Cumulus clouds are puffy or billowy and resemble piles of cotton. Stratus clouds are formed when warm moist air rises over cold air. Stratus clouds resemble a blanket spread out across the sky.

Which of the following is the main idea of the paragragh?
A.The effect of moisture in the air
B. The correct categorization of clouds
C. The description of cumulus clouds
D. The formation of clouds

Answer 1

The main idea of the paragraph is the formation of clouds, focusing on how cumulus and stratus clouds are created through different processes in the atmosphere.

Step-by-step explanation:

The main idea of the paragraph is the formation of clouds. The paragraph discusses two main types of clouds, cumulus and stratus, emphasizing how different atmospheric conditions contribute to their formation. Cumulus clouds are described as resulting from moist air warmed by convection and rising quickly, often leading to a positive feedback mechanism where condensation releases energy, driving the clouds higher. In contrast, stratus clouds are formed when warm, moist air gently rises over cooler air, creating a blanket-like appearance across the sky.
