Climate
        Climate is the long-term pattern of weather in a particular area. Weather can change from hour to hour, day to day, month to month or even from year to year. For periods of 30 years or more, however, distinct weather patterns occur. A desert might experience a rainy week, but over the long term, the region receives very little rainfall. Because climates are mostly constant, living things can adapt to them. Polar bears have adapted to stay warm in polar climates, while some plants have evolved to hold onto water in dry climates.
