Can someone with these questions? ?
oceans :
keep worldwide temperatures constant
reduce atmospheric co2
minimize rapid temperature fluctuations
all of the above
about 96% of sea water is made of:
nitrogen
carbon dioxide
sodium and chloride
hydrogen and oxygen
salinity:
is expressed in parts per 1,000
refers to the amount of dissolved particles in sea water
is denoted by the symbol ‰
all of the above
about 330 million cubic miles of water cover the earth.
true
false

1) All the options are true, large masses of water help to regulate the temperature, control temperature fluctuations and reduce the atmospheric CO2-

2) The "common" water is made of H2O, this means that it is made of hydrogen and oxygen, so the right answer is the fourth option.

3) Salinity is expressed in (gr of salt)/(kg of water), so is expressed in parts per 1000, it refers to the amount of dissolved salt in water (not any particle, and not only in seawater, so the option 2 is wrong)

and is represented by the sign %, which means percent.

So the only correct option is the first one.

4) True, it's around 333 million cubic miles of water.
