What is the simple meaning of cloud cover?

Correct answer: Amount of clouds in the sky

Answer: A, the amount of clouds in the sky. Cloud cover describes how much of the visible sky is occupied or covered by clouds at a particular time and place. It is not simply a statement that clouds exist; it refers to their extent or proportion across the sky. A small amount means much of the sky is clear, while extensive cover means only a small part may appear clear. A is correct because it gives the simple meaning of cloud cover. B, river flow, describes the movement or discharge of water in a river. C, soil colour, refers to the appearance of soil and may depend on minerals or organic matter. D, sea depth, means the vertical distance from the surface of the sea to the bottom. None of these measures the visible spread of clouds. Memory cue: cover means “how much is covered”; cloud cover means how much sky is covered by clouds.
