A. denser
B. younger
C. more colorful
D. more deformed
E. more magnetic

Answer 1

A positive gravity anomaly within a surveyed section of the Earth's crust could be caused by rocks that are locally denser than the surrounding rocks.

Step-by-step explanation:

A positive gravity anomaly within a surveyed section of the Earth's crust could be caused by rocks that are locally denser than the surrounding rocks.

When rocks have a higher density, they exert a stronger gravitational pull and result in a positive gravity anomaly.

This can be caused by the presence of denser minerals or rocks with a higher concentration of heavy elements.
