What is the difference between salinity and density. 5. how does this relate to the deep currents of the ocean?

Salinity is the concentration of salt dissolved in water while density is the ratio of mass over volume. In general, they are directly related - as salinity increases, the density of water increases as well. So in deep ocean, the dense water with higher salinity will sink below less dense water. The density difference will create flow between shallow and deep ocean water.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
