Egypt is located in the continent of Africa. Most of Egypt is covered by the Sahara Desert. Pyramids, which were difficult to build, are found in Egypt and may contain mummies or treasures inside. The longest river in the world, the Nile River, flows through Egypt and was important for agriculture. Another structure found in Egypt is the Sphinx, which has the body of a lion and the head of a pharaoh. Ancient Egyptians also used hieroglyphics as a form of writing.
