A mineral forms from water at the edge of a lake.
Which statement best describes this mineral?
A:The mineral formed from lava.
B:The mineral formed through evaporation.
C:The mineral formed when hot water cooled.
D:The mineral crystallized from magma.
Answers
However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out. This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
a) Granite is rock that forms from slowly cooled magma, containing the minerals quartz (clear), plagioclase feldspar (shiny white), potassium feldspar (pink), and biotite (black). When magma erupts onto Earth's surface, it is called lava. Lava cools much more rapidly than magma when it is below the surface.
b)As the water of the lake evaporates due to high sunlight intensity, the lake waters become saturated because the reduced volume of the lake still dissolves the same amount of mineral elements. The minerals begin to crystallize and precipitate to form salt rocks. As the waters of the lake shores recede due to evaporation, the salty rocks are exposed.
c)The minerals present will be olivine, pyroxene, and calcium-rich plagioclase. If the magma cools slowly underground, the product will be gabbro; if it cools quickly at the surface, the product will be basalt.

B. the mineral formed through evaporation.
