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.
The correct answer is lake titicaca

<u>Advantages of airborne gravity gradiometry:</u>
1) consistent regional coverage
2) It is used when the data is large and it is fast
3) It can be used in varied topography
4) This provides multiple information about a constraint to solve it.
<u>Applications of airborne gravity gradiometry:</u>
Ground gravity survey provide detailed characterization and a higher resolution of a survey area and is comparatively cheap and non destructive. Airborne gravity gradiometry can be used in geothermal exploration, field procedures on an aircraft, environmental mitigation measures on an aircraft.
