High school stuff:
Asia is often divided into culturally and geographically similar regions. Although definitions, names, and borders can vary, generally the regions of Asia include West Asia (which is part of the Middle East), the Caucasus (sometimes also considered as part of the Middle East), Central Asia, East Asia, South Asia (also called the Indian Subcontinent), and Southeast Asia. West Asia is sometimes referred to as the Middle East, with is actually a misnomer since the cultural region we define as the Middle East often included countries outside of Asia, such as Egypt in Africa and Cyprus in Europe. West Asia specifically includes the countries within the region of Asia bordered by the Mediterranean and Red Seas to the West and the Persian Gulf, the Gulfs of Aden and Oman, and the Arabian Sea to the South. Countries within West Asia include Afghanistan, Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, Turkey, the United Arab Emirates, and Yemen.
