Answer:
Quartz is not pure in this rock.
Explanation:
When quartz shows effervescence in contact with an acid, it means that it is not in its pure state, but rather related to other substances that may be cementing the quartz. This effectiveness is caused by substances that do not react like quartz, such as calcite.
In this case, we can conclude that in relation to the calcium-rich rock shown in the question above, the calcium is not pure, but it is likely to be related to calcite, or other material that does not react to acid.
Gravity plays an important role in the separation of liquids because it determines the volume of liquids, and therefore, it affects the density.
When you mix different liquids they often separate forming defined layers. This process is possible due to the differences in density (mass/ volume). In this way, the liquid with a lower density will float over the liquid with a higher density.
This phenomenon is affected by gravity or the force that makes everything on the Earth to be pulled towards the center of it. This is because gravity exerts pressure over bodies and affects the volume, which is one of the factors that determines density.

<span>A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle. As the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
