Alps facts for kids

Kids Encyclopedia Facts

The Alps are the biggest mountain range in Europe. They stretch from Austria and Slovenia in the east, all the way through Italy, Switzerland, Liechtenstein, and Germany, to France in the west. The name 'Alps' originally meant 'white'.

The tallest mountain in the Alps is Mont Blanc. It stands at 4,808 metres (15,774 ft) high, right on the border between Italy and France.

Where are the Alps?

The Alps are a huge mountain range that goes through eight different countries. These countries are France, Italy, Switzerland, Liechtenstein, Germany, Austria, and Slovenia.

The Alps are split into two main parts: the Western Alps and the Eastern Alps. A line from Lake Constance to Lake Como, following the Rhine River, divides them.

  • The Western Alps are found in France, Italy, and Switzerland. They have taller peaks but are a bit shorter and more curved.
  • The Eastern Alps are in Austria, Germany, Italy, Liechtenstein, Slovenia, and Switzerland. This part of the range is longer and wider.

The highest peaks in the Western Alps include Mont Blanc (4,808 metres (15,774 ft)), Mont Blanc de Courmayeur (4,748 metres (15,577 ft)), and the Dufourspitze (4,634 metres (15,203 ft)). The tallest peak in the Eastern Alps is Piz Bernina, which is 4,049 metres (13,284 ft) high. Many people especially love visiting the Swiss Alps.

The Main Mountain Chain

The main chain of the Alps follows the watershed (the line where water flows in different directions). This line goes from the Mediterranean Sea all the way to the Wienerwald. It also marks the northern border of Italy.

This main chain includes many of the Alps' most famous and highest mountains. It starts by going west, then turns northwest, and finally north near the Colle della Maddalena. When it reaches the Swiss border, it heads northeast until it ends near Vienna.

Mountain Passes

The Alps are not a solid wall that stops people from crossing. For thousands of years, people have traveled through them for trade, wars, and later, as pilgrims, students, and tourists.

Mountain passes are like natural pathways through the mountains. They allow roads, trains, or walking trails to cross from one side to the other. Some of these passes are very famous because they have been used for a very long time.

The Tallest Peaks

An organization called the Union Internationale des Associations d'Alpinisme (UIAA) has listed 82 "official" Alpine peaks that are over 4,000 meters (about 13,123 feet) high. Many of these are smaller peaks, but they are important for mountaineering.

Here are twelve of the most important 4,000-meter peaks, each standing out significantly from its surroundings:

Name Height (meters, feet) Mountain Range
Mont Blanc 4,810.45 m (15,782 ft) Graian Alps
Monte Rosa 4,634 m (15,203 ft) Pennine Alps
Dom 4,545 m (14,911 ft) Pennine Alps
Weisshorn 4,505 m (14,780 ft) Pennine Alps
Matterhorn 4,478 m (14,692 ft) Pennine Alps
Grand Combin 4,314 m (14,154 ft) Pennine Alps
Finsteraarhorn 4,273 m (14,019 ft) Bernese Alps
Aletschhorn 4,192 m (13,753 ft) Bernese Alps
Barre des Écrins 4,102 m (13,458 ft) Dauphiné Alps
Gran Paradiso 4,061 m (13,323 ft) Graian Alps
Piz Bernina 4,049 m (13,284 ft) Bernina Range
Weissmies 4,023 m (13,199 ft) Pennine Alps

Around 1900, Karl Blodig was the first person to climb all the main 4,000-meter peaks.

How the Alps Formed

Mountains usually form when huge continental plates of the Earth's crust push against each other. The Alps were created by the slow but powerful pressure of the African plate moving north and crashing into the stable Eurasian landmass. Italy, which was once a separate island, was pushed into Europe during this process.

This mountain-building happened mostly during the Tertiary period, especially in the Miocene and Pliocene epochs. This was about 35 to 5 million years ago.

The Alps are part of a much larger chain of mountains called the Alpide belt. This belt stretches across southern Europe and Asia, from the Atlantic Ocean almost all the way to the Himalayas. There is a gap in these mountain chains in central Europe that separates the Alps from the Carpathians to the east. This gap formed because the land sank in those areas.

Millions of years ago, a huge, ancient ocean called the Tethys Ocean existed between Africa and Europe. Today, the rocks and sediments from this ocean basin are found high up in the Alps. Even very old metamorphic rocks are found on peaks like Mont Blanc, the Matterhorn, and other high mountains in the Pennine Alps and Hohe Tauern.

The Mediterranean Sea as we know it today formed more recently.

Visitors and Activities

The Alps are a very popular place to visit, both in summer and in winter. They are great for sightseeing and many different sports.

  • Winter Sports: From December to April, you can enjoy activities like Alpine and Nordic skiing, snowboarding, tobogganing, and snowshoeing. Many places offer lessons for beginners.
  • Summer Activities: In summer, the Alps are perfect for hikers, mountain bikers, paragliders, and mountaineers. There are also beautiful alpine lakes where people can go swimming, sailing, and surfing.

The larger towns and lower areas of the Alps are easy to reach by highways and main roads. However, higher mountain passes and smaller roads can be difficult to drive on, even in summer. Many passes are closed during winter because of snow.

Many airports around the Alps, and some within the mountains, make it easy for travelers to arrive from other countries. There are also good train connections. The Alps welcome over 100 million visitors every year!

Climate Zones

The Alps have five different climate zones, each with its own unique environment. The climate, plants, and animals change as you go higher up the mountain.

  • Névé Zone: This is the area above 3,000 meters (about 9,800 feet). It's the coldest zone and is always covered in thick, compressed snow. Very few plants can grow here.
  • Alpine Zone: This zone is between 2,000 and 3,000 meters (about 6,500 to 9,800 feet) high. It's not as cold as the névé zone, and you can find wildflowers and grasses growing here.
  • Subalpine Zone: Just below the alpine zone, this area is 1,500 to 2,000 meters (about 4,900 to 6,500 feet) high. The temperature starts to get warmer, and you'll see forests of fir and spruce trees.
  • Arable Zone: This zone is about 1,000 to 1,500 meters (about 3,300 to 4,900 feet) high. Millions of oak trees grow here, and it's also where a lot of farming takes place.
  • Lowlands: These are the areas below 1,000 meters (about 3,300 feet). A wider variety of plants grow here. Many villages and towns are also located in the lowlands because the temperature is more comfortable for people and farm animals.

The Alps are a great example of how temperature changes with height. As you go higher up a mountain, the temperature drops. Mountain ranges also affect winds, causing warm air from lower areas to rise, cool down, and release snow or rain.

Plants of the Alps

The common trees in the Alps, like oak, beech, ash, and sycamore maple, have a natural height limit called the 'tree line'. This limit shows where the climate becomes too cold for these trees to grow.

  • On the north side of the Alps, the tree line is usually around 1,200 metres (3,940 ft) above sea level.
  • On the southern slopes, it can reach 1,500 metres (4,920 ft), and sometimes even 1,700 metres (5,580 ft).

However, people have cut down many of the original forests in the Alps. Except for some beech forests in the Austrian Alps, you won't find many of the typical deciduous tree forests. Instead, you'll often see Scots pine and Norway spruce trees. These trees are tougher and less affected by goats eating their young saplings.

Above the tree line, there's often a band of dwarf pine trees (Pinus mugo). These are often replaced by dwarf shrubs like Rhododendron ferrugineum (on acid soils) or Rhododendron hirsutum (on non-acid soils).

Even higher up is the alpine meadow, where plants become less common. At these very high altitudes, plants tend to grow in separate groups. Many different kinds of flowering plants have been found above 4,000 metres (13,120 ft) in the Alps. Some examples include Ranunculus glacialis, Androsace alpina, and Saxifraga biflora.
