PHYSICAL GEOGRAPHY – 4e Mountains

A mountain is a landform that rises high above its surroundings. Taller than a hill, it usually has steep slopes and a rounded or sharp peak. Mountains are rarely found alone. Groups of mountains are called ranges. Lines of ranges form mountain belts.

Some mountains were formed by the activity of volcanoes. Scientists believe that most volcanic mountains are made up of rock that melted deep within Earth. The molten rock then rose through Earth’s surface, or crust. It then flowed onto the surface in the form of lava. The lava, along with volcanic dust, built up to form mountains. Volcanic mountains are typically steep and cone shaped. Mount Fuji in Japan, Mount Kilimanjaro in Africa, and Mount Rainier in the United States are examples of volcanic mountains.

Other mountains were formed by movements within Earth’s surface, or crust. The theory called plate tectonics explains this type of mountain building. Earth’s surface is divided into huge pieces called plates, which move very slowly. The continents sit on top of the plates and move with them. At times the plates collide, forcing the rock upward. The Himalayas of Asia are an example of this type of mountain chain. They were formed when a plate carrying India collided with the Asian plate.

Mountain ranges are natural barriers to travel. Roads are difficult to build across them. Railroads need expensive tunnels to cross even low mountains. Therefore mountain ranges tend to divide the people on either side of them. They often form borders between countries. Life is hard in mountain lands. The high places of the world are cold and have little soil, making farming difficult. However, many mountain areas are vacation resorts. Skiing and climbing are popular mountain sports.
