What differentiates ground water from surface water?

  1. a gasoline substitute consisting of 90% gasoline and 10% grain alcohol from corn

  2. the state of matter distinguished from the solid and liquid states by relatively low density and viscosity

  3. underground water that is held in the soil and in pervious rocks

  4. a segment of DNA that is involved in producing a polypeptide chain

The correct answer is: underground water that is held in the soil and in pervious rocks

Ground water differs from surface water in that it is found underground, in the soil and rocks, rather than on the surface. Option A is incorrect because it describes a gasoline substitute rather than water. Option B is incorrect because it defines a gas rather than water. Option D is incorrect because it defines a segment of DNA rather than water. The only answer that accurately differentiates ground water from surface water is C.
