In relation to natural gas, where is crude oil generally found?
a.
crude oil is found above natural gas reservoirs.
b.
crude oil is found next to natural gas reservoirs.
c.
crude oil is found below natural gas reservoirs.
d.
crude oil is mixed in with natural gas reservoirs.

The correct answer is-

C.  Crude oil is found below natural gas reservoirs.

Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.

Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.

Thus, option C) is the right answer.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
