Geography is the science of our planet, of the world we live in. To one degree or another, geographical knowledge is needed by every person. The name "geography" in ancient Greek means "land description." What will the weather be like the day after tomorrow? What happens if you connect two rivers with a canal? Should you be afraid of a volcanic eruption? How fast is the Arctic ice melting? What was the climate on our planet three thousand years ago? What seas and rivers are threatened with extinction? Where is it better to grow rice, and where is rye and wheat? What do you think all these questions have in common? At first glance, there can be nothing in common, but this is not so. To answer these questions, you need to know geography.
