Why are bodies of water never really permanent?

Lakes are not permanent features of a landscape. Some come and go with the seasons, as water levels rise and fall. Over a longer time, lakes disappear when they fill with sediments, if the springs or streams that fill them diminish, or if their outlets grow because of erosion.

Where do streams come from?

Explanation: Streams are the smallest stage of rivers. They originate close to springs and are often fed by water runoff following rain. Most of the streams will connect together originating a progressively larger water flow until a river is formed.
