Explanation:
Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.
1- Evaporation: Energy from the Sun causes water to become vapor and rise into the atmosphere.
2- Condensation: The water is cooled in the temperatures of the lower atmosphere, turning it from vapor into liquid water and collect into clouds.
3- Precipitation: The clouds become too heavy to remain in the sky, and it rains.
