Evaporation
The process is called evaporation.
Eh...they are lakes that have dried up. Which is of course why they are called "dry" lakes. Salton Sea in south-east California is a sea (a salty lake) that is rapidly drying up due to the ongoing droughts that have plagued California on and off for several decades now. Aral Sea south of the Russian Federation is another such lake that is disappearing for the lack of rainfall and streams to keep it filled. With the global climate change more and more lakes/seas are drying up due to the resulting extended and more severe droughts. Which is to say the Earth is getting more dry lakes than ever before in modern history.
Silt fills them up and causes more flooding and polution
because there is dry
evaporation
Ones that are empty
It might Ponds often dry up when their sources -- rain, runoff, and rivulets -- don't supply enough water to replenish what is lost via evaporation and seepage. Lakes, on the other hand, rarely dry up because their sources -- rain, runoff, underground springs, and streams -- more than keep up with what is lost. Lakes, themselves,are often sources of rivers.
No, drying up of our eyes causes iritation.
