so this is not same

Answer 2

Answer:

The two continents are commonly referred to as the Americas and are separated by ocean waters, and North America is larger than South America. ... Although the same people previously occupied the two continents, they differ in the predominant languages spoken today.

In modern English, North and South America are generally considered separate continents, and taken together are called the Americas, or more rarely America. When conceived as a unitary continent, the form is generally the continent of America in the singular.
