Which of the following is a nonrenewable energy source? A. Solar
B. Geothermal
C. Hydroelectric
D. Petroleum

Petroleum

Explanation:

Petroleums are fossil fuels.

D

Explanation:

Energy sources are of two categories, renewable and non renewable.

Non renewable resources include fossil fuels (petroleum, natural gas, coal) and nuclear fuel (mostly uranium, which is in limited supply). Use of both of them causes pollution. Fossil fuel cause oil spills, acid rain, air pollution, water pollution etc. Nuclear energy may give rise to radiation pollution.

Renewable resources of energy include biomass energy and some forms of inexhaustible energy like solar energy, hydro power, wind power etc. They are less polluting but far more expensive due to technological incipiency.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
