There are many interesting answers to this question. But I found one very fascinating and amazing phenomenon. When it rains suddenly in the Atacama desert in Chile, which is the driest non-polar desert on Earth, there will be a sudden spur of life in the desert.
If the desert gets heavy rainfall during their spring season which is October and November, there will be a sudden bloom of the flowers ‘hibernating’ beneath its surface. It fills the entire desert with an explosion of color by the flowers coming to their full bloom which is eagerly waiting for the rain, leaving the place as heaven on the earth.
