How does the high specific heat of water maintain the temperature of earth?
a. by heating and cooling more slowly than land or air
b. by heating and cooling faster than land or air
c. by heating faster but cooling more slowly than land or air

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
