There are two things that cause ocean water to become denser, and those are b) the salinity of water and low temperatures.
The more salt there is, the denser the water will be - take the lake Dead Sea in Israel, Jordan, and Palestine for example.
And the lower the temperature, again, the denser the water will be - the deeper you go into an ocean, it will be more difficult to move around due to density and other things.

Answer:
Winds blowing from the ocean
Explanation:
Winds blowing from the ocean contain water vapor making the air more humid, and they also contain the heat which the water contains due to water's  properties of having a steady temperature and high specific heat capacity. 
 
        
             
        
        
        
Answer:
absorb water from the soil by osmosis.
Explanation:
Root hair cells
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption
