how was the mountain formed?

Answer 1

by volcanic eruptions.
and because earth is revolving so That heavier thing go toward outside its center of rotation

Answer 2

The above answers are correct, however a third type is the fold mountain. Frequently they do occur at the junction of two tectonic plates, but not always. The crust is compressed and then forced upward in a fold or folds. The Himalayas are an example of mountains that have formed largely without any direct volcanic activity.

Japan's Fujiyama and Kenya's Mount Kilimanjaro are two examples of mountains that resulted purely from direct volcanic activity (eruption).

The mountains of the Indonesian Archipelago are situated adjacent to the conjunction of two tectonic plates, but they are totally volcanic in origin. Not a fold mountain to be seen there.

Answer 3

There are two ways in which mountains are formed. One is by a volcano. Hot lava wells up from inside the earth where it is hot, and spills out onto the land, making a cone-shaped mountain. The best examples of this type of mountain are the Hawaiian islands which are all made from volcanoes. The island of Hawaii itself is 36,000 feet tall from the base to the tip (the base is far under the surface of the sea) making it the biggest isolated mountain in the world.

The other way mountains are made is by the surface of the earth moving and sliding around. The crust of the earth is not solid but made from a load of separate sections, like a cracked egg shell. These are pushed around by currents in the lava underneath and end up pushing against each other, causing ripples and folds. These are like the folds you get in a rug if you push it with your foot. They produce mountain ranges which are long and straight or slightly curved. A good example of this type of mountain range is the Himalayas. The plate with India on it is crashing into the plate with Tibet on it. Where the two meet, a giant range of mountains is formed. Another good example is the Rocky Mountains which are formed by the North American plate pushing against the Pacific plate.

This sort of mountain is called a fold mountain and can last long after the plates have stopped pushing. The Appalachian mountain range down the east coast of the United States was formed when North America pushed up against Europe many millions of years ago.

Answer 4

A mountain is formed by either the Earth's plates pushing into each other, causing it to project upwards or by a valcano depositing lava over a long period of time, causing the lava deposits to build up and harden into rock.

Answer 5

glacial ice movements from the past and volcanic eruptions
