Chemical rocks are formed by what grow out of solution?

precipitate

Explanation:

Chemical sedimentary rocks are rocks that are formed as a result of precipiation of minerals from solutions. The solutions are usually derived from dissolved loads during erosion. When they get to basins where they settle and more materials are dissolved, the solutions becomes supersaturated. This implies that the solvent contains more than enough solute it can normally dissolve. In this regard, the solution would begin to crystallize and precipitates will form from the solution.

Examples of such rocks are gypsum, limestone, anhydrite, sylvite

i would expect light rain in pittsburgh throughout the following 24 to 48 hours. the lower/falling weights in urban areas toward the west demonstrate that a low weight framework is moving from west to east toward pittsburgh. low weight frameworks are ordinarily connected with precipitation. the way that you don't see a major drop in temperature in the more western urban areas demonstrates the low weight framework is moving with a warm front, so just light rain would be normal. substantial downpours or progressively vicious climate is just typically connected with chilly fronts, where the warm air is pushed up and over a cool front quickly. this quickly rising air (convection) is what gives you heavier torrential downpours, and other conceivably serious weather conditions.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
