Answer:
Front
Explanation:
When two air masses collide, a front is formed. The two most common types of fronts are cold fronts and warm fronts.
Cold fronts are formed by the advance of cold continental polar or continental arctic air towards the south. The colder air wedges underneath the warmer air mass to the south and causes it to rise, forming a storm front.
A warm front is the pushing action done by an advancing mass of maritime tropical warm and moist air that pushes a colder air mass out of the way by rising on top of it gradually and moving it away slowly. This causes an extensive cloud front of light rains.

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.
