The Hydrological (Water) Cycle And Drainage Basin Systems Practice Test

What term refers to visible masses of very fine water droplets or ice particles suspended in the atmosphere?

Confluence Reservoir Clouds Antecedent soil moisture

Correct Answer:

Clouds

Explanation:

Clouds are visible masses of very fine water droplets or ice particles suspended in the atmosphere. They form when moist air rises and cools, causing water vapor to condense onto tiny particles in the air. These countless droplets or ice crystals are light enough to stay aloft, making the cloud visible in the sky. The type and height of a cloud depend on temperature and humidity, and cloud formation is a key step in the weather cycle because it can lead to precipitation. The other terms point to different parts of the hydrological system: confluence is where streams join, a reservoir is water stored for use, and antecedent soil moisture refers to how wet the soil is before a precipitation event.
