In an instant, you should know that Asia includes the two most populous countries on the planet, China and India. The continent consists of 47 countries with nearly 4 billion people, some 60 percent of the world's population. Asia -- also the largest in size of the seven continents -- spans 10 time zones (some say 11), the contiguous United States only four.

Not everyone agrees on what constitutes Asia, since it's part of the Eurasian land mass, but its borders on the west are generally considered to be the Ural and Caucasus Mountains, the Dardanelles in northwest Turkey and the Gulf of Suez/Suez Canal in Egypt. Its other borders are three oceans -- the Arctic, Pacific and Indian. Not a day goes by without news from Asia -- the war in Iraq, resurgence of the Taliban in Afghanistan, military repression against demonstrating monks in Myanmar (formerly Burma), the 2008 Summer Olympics in China, Middle East turmoil, nuclear fears from Iran, astonishing development in Dubai, outsourcing of jobs to India, oil production in Saudi Arabia and the economy in Japan.

Every day we touch something made in Asia -- the clothes we wear, the cell phones we use, the TV sets we watch, toys children play with. Obviously, we all need to know more about Asia -- more than just popular Chinese, Indian, Japanese and Thai food!

Here's a chance to test your geography skills. You'll find questions relating to Asia, but also questions on the rest of the world. Remember, this is not a test with grades, but simply a way to help us all learn more about our planet.
