The correct answer is - from solar nebula.
The Earth and the other planets in the Solar System are thought to have formed from solar nebula. This solar nebula is believed to have been a left over from the Sun's formation, being consisted of gas and dust in a disc-shape. The material in this disc-shaped gas and dust started to merge gradually, thus little by little forming bigger and bigger objects, and as the objects were getting bigger they had bigger gravitational pull so more and more material was attracted toward them. Because of the very big gravitational pull of the Sun these objects were not able to wander into the space but were instead kept close to the Sun. Because of the orbiting around the Sun, they all started to take a rounded shape. Some planets as the Earth, Venus, Mars, and Mercury became terrestrial planets, while the likes of Jupiter, Saturn, Uranus, and Neptune became gas giants.
The relationship between the side of an area on a map and it’s actual size on the Earth’s surface is called scale
The correct answer is - Race and ethnicity shape internal and external perceptions of a group.
Both, the race and the ethnicity, shape the internal and external perceptions of a group of people. It is true that every ethnic group has its own unique traits, and that every race has its own unique features, but unfortunately, very often they are over exaggerated and used in bad connotations.
The people of races and ethnic groups around the world tend to have prejudice for the people different than them, and very often that leads to big problems.
Answer:
Hilly flanks theory
Explanation:
HILLY FLANKS THEORY is the theory proposed by Robert Braidwood, arguing that agriculture arose in areas where the wild ancestors of domesticated wheat and barley grew, and resulted from human efforts to increase the productivity and stability of their food base.
He proposed and suggest in 1948, that agriculture began in the hilly flanks of the Taurus and Zagros mountains, where the climate was not drier, as Childe had believed, and that fertile land supported a variety of plants and animals amenable to domestication.
