People who live in mountains

People Who Live In Mountains
People who live in mountains are called hill people. They live all over the worl but most of them come from Asia. They live in stone houses and usually earn their livings from farms.

This is a picture of the houses the hill people live in.
The aisian hill people live in a mountain range called the Caucasus Mountains. They are located between the Black sea and the Caspian sea in the Caucasus region.

Different types of Mountains


Fold Mountains

Fold mountains are formed when two plates collide head on, and they crumble.
The upward folds are known as anticlines, and the downward folds are synclines.
Some examples of fold mountains are the Himalayan Mountains the Andes Mountains.

Fault-Block Mountains

These mountains are formed when cracks in the earth's crust force rock up to the surface and the other rocks down. The earth's crust then pulls apart. This breaks up the rocks the earths crust pushes to the surface. Overtime the rocks build up on the surface to make a Fault-Block Mountain.Some examples of Fault-Block Mountains are the Sierra Nevada mountains in North America and the Harz Mountains in Germany.


Dome Mountains

Dome mountains are formed when magma pushes up under the earths crust. Without reaching the surface, the magma pushes up rocks above. Overtime the magma cools and forms hardened rock.  The rocks over the hardened magma are pushed upward to form a dome. But the rock layers of the surrounding area remain flat. An example of dome mountains are the Sierra Nevada range in California.
Volcanic Mountains
Volcanic Mountains are formed when magma deep in the earth, erupts, and ends up on the surface. When the ash and magma cools, it becomes a cone of rock. Rock and magma pile up overtime. Some examples of volcanic mountains are Mount St. Helen's in North America, Mount Pinatubo in the Philippines and Mount Kea and Mount Loa in Hawaii.


 
Erosion Mountains
Erosion mountains are formed by erosion. They are formed from a plateaus being eroded. Erosion mountains are usually found near folded mountains. Overtime, streams and rivers erode valleys through the plateau, leaving erosion mountains standing between the valleys. An example of erosion mountains are the mountains in New Zealand.

how mountains are formed

Mountains are formed when magma from underneath the Earth’s crust is pushed up, but doesn’t actually break through the Earth's crust. The magma overtime cools and hardens into hard rock. The layers of softer rock above the hard rock, made by the magma erodes away and you’re left with a large dome-shaped mountain. Overtime the magma breaks throught the hard rock and a volcano is formed.

There is another main way of how mountains are formed. The Earth’s  plates crash together. Because their is so much force in this collision, the sides of the plates crumple. Mountains are created because of those crumpling plates.

This blog is about mountains. I am going to write about how a mountain is formed, the animals and plants that live in a mountain, the different type of mountains, the people who live on mountains and the different activities you can do on a mountain.
