Verified
Once oil and gas are formed, they:
A) rise toward the surface
B) are lighter than water
C) flow most easily through permeable rocks, such as sandstone
D) can be prevented from reaching the surface if they are trapped by impermeable layers
E) all of these
Impermeable Layers
Geological strata that do not allow the passage of water or fluids due to their tightly packed nature.
Permeable Rocks
Rocks that contain pores or cracks through which fluids such as water can easily pass.
Oil And Gas
Natural hydrocarbon resources extracted from the Earth, used as fuels and in the production of various chemicals and materials.
- Recognize underground characteristics suggestive of oil and gas deposits.
- Learn the methodology involved in transforming organic material into oil and gas.
- Identify the function of permeable and impermeable strata in the entrapment processes of oil and gas.

Final Answer :
E
Explanation :
Oil and gas are less dense than water, which causes them to rise toward the surface. They flow most easily through rocks that have high permeability, such as sandstone. Their ascent can be halted by impermeable rock layers, which trap them and form reservoirs. Therefore, all the statements A, B, C, and D are correct descriptions of the behavior of oil and gas once they are formed.
