A mountain can be described as a natural elevation of the earth’s surface rising more or less abruptly to a summit, and attaining an altitude greater than that of a hill, usually greater than 2000 and above.
Physically a mountain is generally steeper than a hill and are formed through tectonic forces or volcanicity. Mountain Gahinga, is an extinct volcano in the Virunga ranges, it lies on the border between Rwanda and Uganda. These forces are recorded to play a key role as they locally raise the surface of the earth. Mountains erode slowly through the weather conditions, action of rivers, and glaciers.
A few mountains are isolated summits, but most occur in huge mountain ranges of African countries like Uganda. It is obvious that mountains with high elevations, produce colder climates than at sea level which inturn affects the ecosystems of mountains. Different elevations have different plants and animals and that’s why in areas with less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing.
Mountain Everest is recorded to be the highest mountain on Earth and can be found in the Himalayas of Asia, raised to a summit of 8,850 m above sea level. Olympus Mons is also recorded to be the the highest known mountain on any planet in the Solar System found on planet Mars at 21,171 m.
Geology of Mountains: It has been recorded that there are only 3 main types of mountains ie; volcanic, block and fold mountains.
That all the above types of mountains are formed from plate tectonics; when portions of the Earth’s crumple, crust move and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward,this in turn creates a landform higher than the surrounding features.
What determines the landform whether is either a hill or a mountain is the height it stands on, if it is higher and steeper then becomes a mountain. Taller mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity.
