What are the Rocky Mountains made of

The formation of mountains and mountain ranges

Mountains are extensive, larger elevations on the surface of the earth, which clearly stand out from lower areas. Such a mountain landscape is divided into mountains, plateaus, valleys and depressions. Mountains and mountains are created either by the forces that are caused by the movement of the earth's crust (this is also called plate tectonics), or they have their origin in volcanic processes (Volcanism).

The shape of the mountains and mountain ranges, which were created or unfolded by plate tectonics and volcanism, is also shaped by the effects of wind, water, sun and ice. Rivers cut into the valleys of the mountains, and large glaciers have sharpened entire areas in the past. These external influences, by which the high elevations on the earth are influenced and removed, are also called erosion. As a result of erosion, even the highest mountains and mountain ranges become flatter again over the course of many millions of years. Mountains that are of volcanic origin, on the other hand, can increase in height again when a volcano erupts when large amounts of lava and ash are thrown to the surface.
On earth there are not only mountains and mountain ranges that can be clearly perceived on the earth's surface (i.e. in the landscape), but also many undersea mountains.


Some of their tips protrude clearly visible from the sea and then form islands. A particularly large mountain in the sea is that Mauna Loathat forms the island of Hawaii. At 4,169 meters, it rises above sea level. But under water, its base is another 5000 high. Thus, if you measure its height from the sea floor, this mountain is, for example, much higher than Mount Everest.

In Europe they count Alps to the largest mountain ranges in the world. In America they are Rocky mountains and the To the, and in Asia the Himalayaswhere there are mountains over 8000 meters high.

According to their height differences, the mountains are divided into High mountains and Low mountain range one, whereby the limit of differentiation is approximately at an altitude of 1500 to 2000 meters.
