why are north and south america different continents
Continent North America and South America are treated as separate continents in the seven-continent model. However, they may also be viewed as a single continent known as America or the Americas. This viewpoint was common in the United States until World War II, and remains prevalent in some Asian six-continent models.[11] This remains the more common vision in Latin American countries, Spain, Portugal, France, Italy and Greece, where they are taught as a single continent.
