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.
Fractional Crystallization
Answer:
The answer to this question is. The Huang He river often floods and when that happens, it can be disastrous. The floods damage homes, livestock, and has even caused fatalities. Dams have also never been able to fully contain the river.
