It actually depends on where you're from. I assume (maybe incorrectly it would seem) that you are from an english speaking country so for you "America" is two separate continents.
The Americas consist of the land mass located to the east of the Pacific Ocean and the west of the Atlantic Ocean, and are generally divided into North America, South America, and Central America. The term also usually includes the Caribbean, the islands in and around the Caribbean Sea, and Greenland, though not Iceland, for cultural and historical reasons. The isthmus of Central America is usually considered geographically part of North America. The Americas are often also described collectively as the Western Hemisphere or, during the colonial era, as the New World.
The classification of the Americas as a single continent vs multiple continents is debated. Traditionally in English-speaking countries, North and South America are considered two continents, reflected by the use of the plural name the Americas. In many other countries, they are considered a single continent, so (an equivalent of) the singular America is used in several languages, though it should be noted that even those who consider the Americas to be two continents may still use the singular to refer to the two collectively. The singular America is also found in English in reference to the pre-Columbian or early Columbian era, such as in the common phrase "Christopher Columbus discovered America". The single-entity concept also appears thematically. For example, the five rings of the Olympic flag represent the five parts of the world, with a single ring representing all of the Americas.
