The Asian continent is the largest of all continents. Covering about 30% of the world's land area, it has more people than any other continent with about 60% of the world's total population. Stretching from the icy Arctic in the north to the hot and steamy equatorial lands in the south, Asia contains huge, empty deserts, as well as some of the world's highest mountains and longest rivers.
Some European countries are also partly in Asia. About three-quarters of Russia is in Asia, while the rest is in Europe. Small parts of four other Asian countries are in Europe; Kazakhstan, Georgia, Azerbaijan and Turkey.
