A stye is an infection of an oil gland in the eyelid. It produces a red, swollen, painful lump on the edge or inside surface of the eyelid. Styes usually occur closer to the surface of the eyelid than do chalazia.
The most abundant salts in the ocean are chlorine, sodium, magnesium, sulfur, calcium, and potassium. Ocean salinity is affected by multiple factors including ice melt, inflow of river water, evaporation, precipitation, wind, wave motion, and ocean currents.
The main one is sodium chloride, often just called salt. Most seawater has about 35g (7 teaspoons) of salt in every 1000g (about a litre2) of water. This doesnât sound very much, but it would take three 6m shipping containers full of salt to make an Olympic-size swimming pool as salty as the sea.
