==Effect of depth==
==Effect of depth==
The amplitude of the gravity signal varies as a function of 1/depth<sup>2</sup> to the source. [[:file:applying-gravity-in-petroleum-exploration_fig15-5.png|Figure 2]] shows the gravity responses to a body of positive density contrast buried at different depths. The upper half of the diagram shows the gravity responses (labeled A, B, and C) to a body buried to depths A, B, and C, shown in the cross section in the lower half.
