The process above is a description of mineral crystal formation.

The given blank can be filled with mineral crystal formation.

Explanation:

The majority of the water on Earth, like the water in the oceans, comprises minerals. The minerals get amalgamated thoroughly with the water to form a solution. The particles of mineral in water are so small that they do not get separated when one filters the water. However, there are certain procedures, which makes the minerals in water to produce solid mineral deposits.  

In order for the minerals to crystallize, the water requires huge concentrations of dissolved minerals. Some of the lakes and seawater are enough salty for the minerals to precipitate out as solids. After the evaporation of water, a solid precipitate of minerals is left behind that does not get evaporated.  

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
