Spiritual gifts are not innate, natural talents, like an ear for music or the ability to draw, but rather they are empowerments that the Holy Spirit gives to a believer to minister to the body in ways that were not possible by mere natural effort apart from the Holy Spirit.
In the design of a dam, the first step is the determination of various forces which acts on the structure and study their nature. Depending upon the situation, the dam is subjected to the following forces: 1. Water pressure. 2. Earthquake forces. 3. Silt pressure. 4. Wave pressure. 5. Ice pressure. 6.
But the system given in the example was a rigid object. What about fluids? The answer may be known to you, liquids gain pressure with increasing depth because there is more bulk applying pressure(or force for that matter) from above. Hence dams have broader base and without protective gear humans can easily get crushed below a certain depth in water. Now, earth below the solid crust is magma, which is molten metallic mixture basically. So, a viscous fluid. Hence, does the density of earth increase with increase in depth. PS- upvote if helpful :P
