Brass is a solid-solid solution (all alloys are). Carbon dioxide is a compound. Oxygen is an element (and so is anything else on the periodic table). Salt water is a solid-liquid solution of salt in water. Raisin Bran is a heterogeneous mixture of raisins in bran flakes. Sugar water is a solid-liquid solution of sugar in water. Chocolate chip cookies are an albeit delicious heterogeneous mixture of chips in cookie dough (and the dough itself is a homogeneous mixture). Gatorade is a solution of whatever's in it and water (who knows whats in that stuff). Lead is an element. Caesar salad is a heterogeneous mixture of lettuce and other stuff. I don't know what calcour is. Whole milk is usually homogenized, but otherwise is a heterogeneous mixture of cream and whey. Skim milk is a homogeneous solution (whey). Hydrogen peroxide is a compound. Potassium is an element. Sugar is a compound (glucose, fructose, sucrose, or such like).

Answer from: Quest

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
