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:
Consumption of chicken has increased in developed countries.
The number of people who farm for a living in less developed countries declines.
Consumers in developed nations spend less of their total income purchasing food.
Food processors play an increased role in food production in both less and more developed countries.
Consumption of various grains has increased in developed countries
Explanation:
Answer:
80 loaves of bread
Explanation:
I think the answer is 80 because if he makes 20 loaves of bread each morning, and 10 more every half an hour for three hours ( 20 + 60 = 80) the answer should be 80. Correct me if I'm wrong please, Thank You!
Answer:
a jet stream that brings alternating warm and cold periods
Explanation:
Jet streams are known as a composition of powerful wind that normally moves from west to east all over the world.
According to various research, it is considered strongest in winter, specifically showing a strong effect on weather in North America.
A jet stream at a normal pace is associated with normal cold and occasional warms, but at a strong pace, it usually creates heavy cold moving and warmth from north to south and vice versa. This is known as Rossby waves.
Hence, in North America, a winter weather change that might be associated with large amplitude Rossby waves is " a jet stream that brings alternating warm and cold period"
