Lakes are temporary storage places for water moving in the water cycle
Detailed Description
Lakes are an important component of the natural water cycle
A lake really is just another component of Earth's surface water. A lake is where surface-water runoff and groundwater seepage have accumulated in a low spot, relative to the surrounding countryside. A lake really is just another component of Earth's surface water. A lake is where surface-water runoff (and maybe some groundwater seepage) have accumulated in a low spot, relative to the surrounding countryside. It's not that the water that forms lakes get trapped, but that the water entering a lake comes in faster than it can escape, either via outflow in a river, seepage into the ground, or by evaporation. And if humans live nearby, then water levels can be affected by water withdrawals for human needs.
