Major Mountains of the World
Transcript of Major Mountains of the World
The Andes were the original home of llamas and wild tomatoes, among other things. About 300 million years old. The Atlas Mountains range across a northern stretch of Africa extending through Morocco, Algeria, and Tunisia. The Atlas ranges separate the Mediterranean and Atlantic coastlines from the Sahara Desert. Before the continents broke apart, the Appalachian Mountains and the Atlas mountains were in the same chain. stretching from Austria and Slovenia in the east through Italy, Switzerland, Liechtenstein, Germany, France and Monaco in the west. 50 million years old. The Himalayas are older than the Alps, but they're younger than the Rocky Mountains. The Himalayas separate India from the rest of Asia, forming the border between India and China and between India and Central Asia. The word Himalayas comes from the Sanskrit phrase "home of the snow", because the Himalaya mountains are high enough to always have snow on them. They are the highest mountains in the world.
Even today, the Himalayas are still growing and getting higher and higher. The Ural Mountains run from north to south through Central Asia, separating Europe from Asia. Like the Appalachian Mountains, the Ural Mountains formed about 300 million years ago. But the Ural Mountains are not as eroded as the Appalachians; some of them still have glaciers at their tops all year round.
The Ural mountains, together with the Appalachians, are among the oldest mountains in the world. They are far older than the Alps, the Himalayas, the Rockies, or even the Andes, which are the next oldest major mountains. The Alps are a long row of mountains dividing southern Europe from Northern Europe. They formed about 34 to 23 million years ago. There must have been lots of volcanoes erupting all over the place and huge earthquakes as this happened. But it didn't happen all at once. The plates only move less than nine centimeters a year, so the mountains would have taken millions of years to form.
Today the Alps are older mountains, and there are no longer any active volcanoes in the Alps, but they are still growing between a millimeter and a centimeter each year!
