Which composition of water moves within a deepwater current?

A. warm and low salinity

B. cold and low salinity

C. warm and high salinity

D. cold and high salinity

D.

Cold and high salinity

Explanation:

Warmer waters are less dense than cooler/ cold waters. This is why surface ocean currents are made of warmer waters while deeper currents are cooler. The deep currents also have a higher salinity. This is because cooler water gets more concentrated faster by dissolving the same amount of solutes (in this case ocean mineral salts) compared to warm waters. This also makes deepwater currents them denser.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
