Welcome back to LearnCenter! Today's topic is OCEANS
An ocean is a body of water that composes much of a planet's hydrosphere. It contains saline water. Salinity depends on rate of evaporation, amount of precipitation and amount of fresh water.
Oceans are warmest near the equator and become cooler towards the poles. Oceans are constantly in motion. Movements are caused by temperature difference, salinity difference, density variation and prevailing winds
