2. QUESTIONS Salt in the oceans comes from rocks (F) Most from the salt is sodium chloride= table salt (T) Water pressure is the amount of salt water (F) Ocean have the saltiest water on Earth(F) The salinity of the oceans change a lot from place to place (F) Something else that depends on the ocean pressure is depth(F) At the surface the water is warmed by sea animals (F) 75% of the oceans has a temperature between 0° c and 3°c (F) To study the oceans scientist use planes or helicopters (F) Some of the conditions of the oceans depends on the water surface (F)
3. ANSWERS FALSE: Salt in the oceans comes from minerals that are washed out from land. The downward push of water is called water pressure. The saltiest water is of Dead Sea, a lake from Israel. The salinity doesn´t change much from place to place. Something else that depends on the ocean´s pressure. At the surface the water is warmed by the sun and by warm air above the surface. Is about 90%. The ocean has a temperature between 0°C and 3°C. To study the ocean the scientist use submarines. But other condition depends on the temperature not water surface.
