Convection currents occur in oceans because of differences in the density of ocean water. One reason that ocean water has different densities is due to the uneven heating and cooling of ocean water. Water that is warmer is less dense, and water that is cooler is more dense.
What other factor impacts the density of ocean water?
A.
Ocean water with a high salt concentration is more dense than ocean water with a low salt concentration.
B.
Ocean water that is frozen as a glacier is more dense than ocean water in liquid form.
C.
Ocean water that is closer to the equator is more dense than ocean water that is farther from the equator.
D.
Ocean water that is closer to land is more dense than ocean water that is farther from land.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
