Asia
In short
Asia is the world's largest continent by both land area and total population. It covers over 44 million square kilometres and is home to nearly 60% of all humans.
In plain words
It is a massive part of the Earth that contains many different countries and cultures. Most of the people living on our planet reside within its borders.
A simple example
A person living in Tokyo, Japan, is living on the Asian continent.
Why it matters
Because it holds such a huge portion of the global population, the economy and politics of Asia affect the entire world. It is also where many of the earliest human civilisations began.
Easy to mix up
People sometimes confuse Asia with the Middle East, which is a specific region located within the larger continent.
