Mountain range

geography Maturity 7-9 Next article →

A mountain range is a long line of mountains or hills. These peaks are all connected by high ground. Sometimes, you might see a group of ranges together. This is called a mountain system or a mountain belt. These groups often look and act in similar ways. They usually form from the same big event. Most major ranges on Earth come from plate tectonics. This is how the large plates of the Earth move.

Mountains can change the weather in a big way. When air moves up over a mountain, it begins to cool. This cooling causes rain or snow to fall. This is called orographic precipitation. As the air moves down the other side, it warms up. This side of the mountain is often much drier. This dry area is called a rain shadow. Large ranges like the Andes can split a continent into different climate zones.

Mountains are always changing because of erosion. Forces in nature work to tear them down. Rivers are a very important part of this process. They cut into the bedrock and carry bits of rock away. These bits are called sediment. This sediment can fill up low areas nearby. Over a long time, mountains can even turn into low hills or plains. For example, the Rocky Mountains once had rock removed by erosion. This rock spread across the Great Plains to the east.

There are many famous mountain ranges on our planet. The Andes in South America is a very long system. The Alpide belt is also huge. It stretches 15,000 km across southern Eurasia. This belt includes the Himalayas and the Alps. The Himalayas have the highest mountains, like Mount Everest. If we look underwater, the Ocean Ridge is the longest system. It is a continuous chain of mountains on the ocean floor.

We can also find mountains in space. On the Moon, mountains often form from impacts. An impact is when something hits a surface. Some mountains in space are made of rock. On Venus, Maxwell Montes is taller than any mountain on Earth. Other moons have mountains made of ice. Saturn's moon Titan has ranges like the Mithrim Montes. Pluto also has ice mountains called the Tenzing Montes. Even Jupiter's moon Io has mountain ranges from tectonic processes.
