"Fresh water" the kind that comes from the tap has additives such as Fluorides. Eye drops are basically sterile water. Water alone is irritating to the eye. Tears are composed of water and salt so the eye drops that do not hurt, contain saline.
Rain is water falling in drops from vapor condensed in the atmosphere. It is also drops of fresh water that fall as precipitation from clouds.
Desalination is the process to change the salt sea water into fresh water to become energy.
they fall back to Earth
hail or snow :)
no< fresh water will become mixed with the salt water
As in the case of all rivers which flow into seas or oceans, the Nile River mixes its fresh water with the salt water of the Mediterranean at its delta. There is no exact point at which a river ceases to be fresh water and become salt water.
pour water (fresh not salt) and wash it. makesure the person is breathing.
You become fresh and healthy, water is life itself
Hail?
precipitation
because the sun ONLY evaporates FRESH water so rain drops are NOT salty.
Chlorine water. Normal fresh water is good and it cleanses your eyes. But chlorine water is fine as long as there's not to much in the pool your eyes may sting and go red afterwards so just splash them with fresh normal water
