Where do mountains come from?

Answer 1

There are several different ways that mountains form.

Fault-block mountain:
If a fault exists in which one rock mass is moving up, and the other is stationary, or moving down, then the upward moving rock mass will form a mountain which rises up from the stationary or downward moving rock The Sierra-Nevada mountains in California are fault-block mountains.

Folded mountains:
When two moving plates push up against each other with extreme force, the crust can bend in an up and down, rolling pattern.

Volcanic mountains:
These mountains form when a hole is torn in the earth's crust. When this happens, plastic rock from the mantel rises up through the hole. The rock from the mantel is hot enough to melt, but the extreme pressure from the mantel keeps the rock in its solid form. When the rock is released from the mantel, a large amount of that pressure goes away, and the rock is free to liquefy, forming molten rock, or magma. This magma pushes against the crust of the earth. When this happens, the crust heaves upwards, forming a mountain. The crust can crack, forming a vent through which the magma can escape, and the result is a volcano. Mount St. Helens in southwestern Washington state is a volcanic mountain.

Domed mountain:
Sometimes, magma escapes from the mantel of the earth, but does not travel directly upwards. Instead, it flows underground. When this happens, the overlying rock is still pushed upward, but a vent is not formed. Thus, the magma is never released, and a volcano doesn’t form. Because the rock is pushed upwards, a mountain that often looks similar to a volcano is formed. Domed mountains are typically rounder and more sloping than a volcanic mountain. The Black Hills in South Dakota are domed mountains.

I hope this answers your question. Have a great day! =D

Answer 2

Some mountains are volcanic in origin forming where rising magma breaks through the Earth's surface. Volcanic mountains tend to have sporadic distributions within a mountain range (Mount St. Helens, Rainier, and Baker) or can occur alone because of a localized hot spot (Hawaiian Islands). Most mountains were created from tectonic forces that elevate, fold, and fault rock materials. Tectonic mountains can occur as a single range (the Urals) or as a belt of several mountain ranges (North American Cordillera). http://www.physicalgeography.net/fundamentals/10k.html

Answer 3

When 2 continental plate move an approch each other and crash the mountain generate beacause none of them can not over lie or under lie to the other one so they make a heigh mountain

Answer 4

Mountains are formed in different ways. Here's a website to get you started:

To find out more, just google 'how are mountains formed?' or 'how are mountains made?'

Answer 5

This happens when the tectonic plates on the earth collide to give us mountains.

Answer 6

the movement of tectonic plates. as they crasehd into each other they create pressure and build up mountains

Answer 7

dont make a mountain out of a molehill!

Answer 8

well when a daddy boulder and a mommy boulder love each very much..they do the hokey pokey and WHAMMO! out comes a mountain..

Answer 9

Several ways. Plate titonics: driven by MAGNETIC FORCES.

Answer 10

i think the movement of plate techtonics
