1. The final arrangement of the natural gas, oil, and water within the sandstone was caused by
differences in their
(1) density.
(2) specific heat.
(3) relative age.
(4) radioactive half-life.
Correct Answer: (1) Layers of liquids and gas will arrange themselves according to their density; with
the most dense materials below the least dense. It can be inferred that water is more dense than oil, which
is more dense that natural gas. (Density)
