Earth is continually changing. erosion leads to areas being slowly covered by dirt and rocks. as more soil gets deposited, it begins to increase the amount of pressure on the rocks, soil, and organic matter underneath. all but one could be formed in this manner. that is a) oil. b) gold. c) diamonds. d) natural gas.

The correct answer is: B)gold.

Oil, diamonds, and natural gas all form over time under significant sustained increased soil pressure. Gold's formation, however, is not due to pressure. Gold is already present in soil and must be mined in deeper layers.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
