Explanation:
The Ural mountains are a natural barrier that separates Europe from Asia. They run from north to south, from the coast of the Arctic Ocean to the Ural River and the country of Kazachstan.
They extend for about 1,600 miles and they are one of the old mountains range in the world. Many rivers originate from the Ural mountains and they contain a number of deep lake. The climate is continental, and they are viewed as a 'treasure box' of mineral resources.
