The Earth Climate
What is Climate? Climate = the average and variations of weather over a long period of time (~30 years) but other periods may be used depending on the purpose. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations. Therefore, climate is “the average and variations of weather over long periods of time”.
