The oceanic crust and the continental crust have different densities. The density of continental crust varies but generally falls in the range of 2.6 to 2.8 g/cm³. The oceanic crust's average density is around 2.9 to 3.0 grams per cubic centimeter (g/cm³).
Oceanic crust, which is primarily composed of basaltic rocks, is denser than continental crust. This higher density is due to the basaltic composition, which is rich in iron and magnesium minerals.
The continental crust, which consists mainly of granitic rocks, has a lower average density compared to the oceanic crust. The lower density of the continental crust is primarily attributed to its granitic composition, which contains lighter minerals like quartz and feldspar.

Answer: Fossil Fuels
Explanation:
The definition of fossil fuels is a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. This fits the examples perfectly, therefore all of the examples are fossil fuels.
Petroleum, coal, and natural gas are non-renewable energy sources. These consume and deplete over time and are the largest contributors to world energy consumption, though they are not sustainable in the long term. Renewable energy sources, which are replenished naturally, offer a more environmentally friendly and sustainable alternative.
Petroleum, coal, and natural gas are all examples of non-renewable energy sources, which are the largest sources of energy. These resources, including fossil fuels and nuclear power, are consumed and depleted over human timescales. Non-renewable sources like these contribute to about 81% of the world's energy consumption.
Fossil fuels, such as the ones listed, transform potential energy into thermal energy through chemical reactions when burned. This thermal energy can be harnessed for uses like heating buildings or operating machinery. Non-renewable energy sources, while currently dominant, have environmental drawbacks such as the release of carbon dioxide and are not sustainable in the long term due to their finite nature.
On the other hand, renewable energy sources like wind, water, geothermal, and solar power are replenished by natural processes and do not deplete over human timescales. These sources currently account for a smaller proportion of the world's energy consumption, but are the focus of significant research and development efforts due to their lower environmental impact and sustainability.

b. 0 to 4 percent
c. 0 to 8 percent
d. 0 to 10 percent
Answer: (B) 0 to 4 percent
Explanation:
The 0 to 4 percent of the water vapor are found in the air. At the point when a volume of the air at the given temperature holding the greatest measure amount of the water fume, then the air is known as the saturation.
In the air, the amount of the water vapor are tend to decreases with the altitude. It is basically due to the temperature, when the temperature are get decreases with the height.
Therefore, Option (B) is correct.
0-4 percent of water can be found in the Air, hence the correct answer is option A.
Air primarily consists of nitrogen. 78% of the air is nitrogen, 21% is oxygen, and 1% is made up of other gases, dust, and water vapor.
Due to the following factors, the air is a mixture rather than a compound: Through fractional distillation of liquid air, the components of air, such as oxygen, nitrogen, and others, can be separated. The characteristics of each gas that is present in the air are visible.
