Answer:
Canada, United States, Brazil, Argentina
Explanation:
The four largest countries by area in the Western Hemisphere are Canada, United States, Brazil, and Argentina. These countries are located in North and South America, with Canada and the United States being in North America, while Brazil and Argentina being in South America. All of these countries are in the top 10 largest countries in the world by area, with Canada being on the second place, the United States on third, Brazil fifth, and Argentina eight. One of the main reasons why these countries are so large is because they are countries of the New World, all being former colonies, where the populations where relatively small, but the European settlers managed to occupy very large areas. Once they gained independence, the boundaries were set in accordance to the colonial boundaries, so instead of having numerous smaller countries divided because of ethnicity, race, or culture, large multiracial, multiethnic, multicultural countries were established.
