Let's talk BMC # 6:
FORMING A MOUNTAIN
Generally, mountains are created over a long period of time by tremendous forces on earth. In the form of Volcanisim and Plate Tectonic Theory. Scientist from the early 1960s developed this theory, it is the collision or movement of continental plates through and towards each other.
Now, if a mountain reaches the elevation of 1,000 ft. / 300 meters above sea level (MASL) or more above its surrounding area, it can be called a mountain as some Geologists classify them.
MOUNTAIN RANGE is a chain of mountains that are linked or joined together. The most famous and largest mountain range in the world is the Himalayas, which can be found in the country of Nepal and Bhutan and the boundaries of India and China. In the Philippines, we have the Sierra Madre which reach out from Cagayan (North) down to Quezon (South) of Luzon.
Classification of Mountains:
1. VOLCANIC - 3 characteristics: Active, Dormant, and Extinct. These mountains were mainly formed by volcanic actions throughout its time.
2. FOLDED - the movement of the two plates forces sedimentary rocks upwards into a series of folds.
3. FAULT BLOCK - is a mountain mass created either by the uplift of land between faults or the subsidence of land outside the faults.
4. EROSION - is the breakdown of the continents and the land around you. The overall effect of breaking down and weathering the land is called denudation.
5. DOME - (Laccoliths) is formed by volcanism. However, unlike volcanoes that erupt to the surface, laccoliths form when magma is injected between two layers of sedimentary rock, causing the overlying strata to bulge upwards (much like a blister on your hand), forming the dome shape.
6. PLATEAU - are similar to dome mountains, but form as colliding tectonic plates push up the land without folding or faulting.
