QUESTIONS1) Salt in the oceans comes from rocks (F)2) Most from the salt is sodium chloride= table salt (T)3) Water pressure is the amount of salt water (F)4) Ocean have the saltiest water on Earth(F)5) The salinity of the oceans change a lot from place to place (F)6) Something else that depends on the ocean pressure is depth(F)7) At the surface the water is warmed by sea animals (F)8) 75% of the oceans has a temperature between 0° c and 3°c (F)9) To study the oceans scientist use planes or helicopters (F)10)Some of the conditions of the oceans depends on the water surface (F)

ANSWERSFALSE:

1) Salt in the oceans comes from minerals that are washed out from land.3) The downward push of water is called water pressure.4) The saltiest water is of Dead Sea, a lake from Israel.5) The salinity doesn´t change much from place to place.6) Something else that depends on the ocean´s pressure. 7) At the surface the water is warmed by the sun and by warm air above the surface.8) Is about 90%. The ocean has a temperature between 0°C and 3°C.9) To study the ocean the scientist use submarines.10) But other condition depends on the temperature not water surface.
