Answer:
Coal is made by heating of woody plant material, and oil is made by heating of algae.
Explanation:
The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.
The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.
The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
Answer:
Countries most likely create internal boundaries to: divide territory for administrative purposes.
1. The government needs to tackle the causes and effects of population decline<span>, for instance by cutting down on the number of new homes being built.
</span>2. When people move away from villages, jobs, schools, shops and other facilities also disappear.
Ok I don't know what chart it is (that would really help) but the global population is around 7 billion not 80 million so unless the chart is from a long time ago (when the population was smaller) I'd go with B. The global population is about 80,000,000
