Africa is the second-largest continent on Earth, with an area of 11.7 million square miles (18.8 million square km). Not surprisingly for such a huge land mass, it is home to an incredible variety of climates, cultures, animals and plants. There are 53 countries in Africa and about 1 billion people. Africa is widely considered to be where human beings first evolved.
The highest mountain in Africa is Mt. Kilimanjaro, which is 19,340ft (5895m) high. The Sahara is the world's largest desert, at 3.5 million square miles (5.6 million square km), nearly the size of the United States of America. The largest city in Africa is Cairo, the capital of Egypt. The Nile is the longest river in the world, at 4,132 miles (6650 km).
The deserts, jungles, and plains of Africa are home to some of Earth's most extraordinary animals. The African elephant is the world's largest land animal. The giraffe is the world's tallest animal. The cheetah is the world's fastest land animal. The gorilla is the world's largest primate.
Most evolutionary scientists believe modern human beings evolved in Africa around 200,000 years ago and migrated to the rest of the world around 60,000 years ago. The first great civilization of Africa was Egypt, records of which go back to 3300 BC.
Africa is such an amazing place that I will have to go visit one day.
