3. What is an exorheic lake?An exorheic lake is an open lake that drains into a river and eventually reaches the ocean. It has a clear outlet that keeps its water fresh.
4. Why do some lakes have no outlet to the sea?Lakes that have no outlet are called endorheic lakes. They stay inside a basin where water can only leave by evaporation or seepage.

Exorheic Basin: A geographical area where all surface water drains towards the ocean via rivers.
Endorheic Basin: A geographical area where surface water collects and does not flow to the ocean, often forming closed lakes.
Evapotranspiration: The combined process of evaporation from surfaces and transpiration from plants.
Percolation: The movement of water through the soil and rock layers beneath the surface.
