Learn the continents by remembering the first letter of each. Of the seven continents six start with the letter "A." Antarctica, Asia, Australia, Africa, and the Americas (North and South) are the six continents that begin with the letter "A."
Know that two of the continents that begin with the letter "A" are the two Americas, North and South.
Learn that the seventh continent is the only one that does not begin with the letter "A" but with the letter "E" instead; that continent is Europe. Remembering that all seven continents begin with a vowel is one way to keep them fresh in your mind.
