Answer 1

Jonathan Avila

Some minerals are soluble in water, and when water evaporates they are left behind often in crystal structures.

Minerals form by evaporation when water containing dissolved minerals evaporates, leaving behind the solid mineral deposits. As water evaporates, its volume decreases and the concentration of dissolved minerals increases. Eventually, the minerals reach saturation and precipitate out of solution, forming solid mineral crystals. This process commonly occurs in environments such as evaporating lakes, salt flats, and hot springs, where high temperatures and low precipitation rates facilitate evaporation. Examples of minerals formed by evaporation include halite (salt), gypsum, and calcite.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
