Answer:
The presence in the air of one or more contaminants in such a concentration and of such duration as to cause a nuisance or to be injurious to human life, animal life or vegetation.
Answer and Explanation:
At the time when Galileo lived, people believed in the geocentric model of the solar system, which claimed that earth was the center of the universe, where all the celestial bodies revolved around it. By using the microscope and discovering Jupiter's natural satellites, Galileo put geocentric systems to the test. This is because he showed that the earth was not the only planet that had celestial bodies rotating around it, other planets had this capacity, like Jupiter. Today we know that Galileo is correct, but his ideas were not well received at the time.
In relation to astronomy, the science of Galileo's time was based on the Aristotelian model, which stated that the celestial bodies were smooth and had a perfect, polished surface with no irregularities. Galileo also put this concept to the test, when he was able to visualize the surface of the moon with his telescope. He saw that the moon did not have a smooth surface, but a rough one, full of irregularities, mountains and caves just like the earth. Today we know that this is true, but one more this idea was not well received by the fellow citizens of Galileo, which caused his life imprisonment for heresy.
We can see that Galileo did not receive a correct judgment from the society in which he lived and suffered for it, even though he was not doing any harm to anyone.
He claimed that they were one large supercontinent called Pangaea. His evidence for his claim was that the general shapes of the separate continents and how they can fit together if you arrange them. He noticed patterns in the mountain ranges; when all the continents are together the ranges line up with one another.
The amount of heat they are exposed to has a lot to do with the inferences and observations that they make on the density of the earth's core. The inner core is the most compact due to the fact that they have a lot of direct exposure to heat and the gravity of the earth pressung down on it. The inner core is less subjected to those conditions.
Radiometric dating should be what they use
