True
Evolution occurs when an organism is born with a mutation and passes that mutation on to its offspring.
I would say this isn't a question but more a lack of experience in a field of science or a subject.
So I will help by giving a brief explanation on what it is.
The study of the Earth's atmosphere and the changes in temperature and moisture distribution that give rise to various weather situations is known as meteorology. Precipitation (rain and snow), thunderstorms, tornadoes, hurricanes, and typhoons are a few of the important topics of research.
Thank you,
