what % of fresh water does glaciers/ice caps make up
around 69%, around 2% in all water
what type of processes decreases salinity
precipitation, melting glaciers/water, and rivers running into the ocean
what processes increase salinity
evaporation and freezing
what are the 3 major ways to change salinity
evaporation/precipitation, glaciation/freezing, and rivers
what is salinity
total amount of dissolved salts into said liquid
what is the halocline
seperation of layers with different salinity
what is a gyre
large system of circulating ocean currents caused by wind
what are the main reasons for places with high salinity
evaporation and freezing
where are places that have very high salinity
medditeranean, red sea, dead sea, persian gulf
how much of the worlds water is fresh
3%
why is the ocean salty
underwater volcanoes and flowing water picks up minerals
what are deep ocean currents driven by
differences in density
