Everything changed during the Industrial Revolution, which began around 1750. People found an extra source of energy with an incredible capacity for work. That source was fossil fuels — coal, oil, and natural gas, though coal led the way — formed underground from the remains of plants and animals from much earlier geologic times. When these fuels were burned, they released energy, originally from the Sun, that had been stored for hundreds of millions of years. Coal was formed when huge trees from the Carboniferous period (345– 280 million years ago) fell and were covered with water, so that oxygen and bacteria could not decay them. Instead, the pressure of the weight of materials above them compressed them into dark, carbonic, ignitable rock. Most of the Earth’s oil and gas formed over a hundred million years ago from tiny animal skeletons and plant matter that fell to the bottom of seas or were buried in sediment. This organic matter was compacted by the weight of water and soil. Coal, oil, and gas, despite their relative abundance, are not evenly distributed on Earth; some places have much more than others, due to geographic factors and the diverse ecosystems that existed long ago.

The story of the Industrial Revolution begins on the small island of Great Britain. By the early 18th century, people there had used up most of their trees for building houses and ships and for cooking and heating. In their search for something else to burn, they turned to the hunks of black stone (coal) that they found near the surface of the earth. Soon they were digging deeper to mine it. Their coal mines filled with water that needed to be removed; horses pulling up bucketfuls proved slow going.
Explanation:Differential association theory suggests that values, attitudes, techniques, and motives that results to criminal behavior are not natural but are learned. Theory of differential association is described using the following propositions:
- People learn criminal behavior
- People learn these behavior through interacting with certain people around them who share such ideas.
- Usually these interactions don't occur with anyone but with the people that a person is mostly closed with.
- During these interactions people learn criminal techniques and they get encouraged through sharing some rationalization of why such activities should be committed.
- people will learn a great deal about legal codes in their geographic area in order to know if their behavior will be successful.
- when people find enough favourable reason to support their intended criminal activities then they will go ahead and commit the crime.
In research, validity refers to whether the data and methodologies that are used in the research actually measures the things that the researchers are targeting.
From the case above, we can see that the searchers want to target Impulsive personality traits among adults but as it turn out the data that is taken is closer to sociable, outgoing, and fun adults (which is exactly the opposite of what';s the researchers are seeking for) Because of this, we can infer that the validity of the research is questionable.
So your parent hasn't joined you on the Brainly express to Achievement-ville. We'll get them on board. Parents are busy people, but you can be the boss and remind them. Remind them how Brainly boosts you with expert knowledge. Remind them that tons of students already get grade upgrades with Brainly Plus. Remind your parent of the power they have to raise you to your full potential. We think they would agree. You deserve every education advantage.
If only one country has the virus then the rest of the world would be less affected so it would be easier to get the supplies and resources needed to help that country recover.
Mexico's economy relies heavily on the United States as an export market. The value of exports equaled 39% of Mexico's GDP in 2019, as shown in Table 1, and approximately 80% of Mexico's exports were headed to the United States.
