Using residual gravity anomaly curves

Some questions worth considering when examining this kind of gravity data are given here. The data are reproduced in the two figures below.

1. These lines could usefully have been a little longer.
True
False
2. Each line of this survey has detected only one zone of geologic materials with anomalous density.
True
False
3. The smaller, central zone, seen under both lines, is more dense than it's host materials.
True
False
4. The zone of increased density is within a region which has higher density than the geologic materials beyond the ends of the survey lines.
True
False
5. The lateral locations of boundaries can be identified from these data.
True
False
6. These data can reveal direct information about the depth extent of buried features.
True
False
