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.
<br /><br /> The average density of water at the ocean's surface is about 1.025 g/ml or 2.5 % greater than pure water. This is due to the mass of added sea salts which is 3.5% or .035 g/ml. The added sea salts have a small effect on the volume, so the resulting combination is more dense than pure water.
