Mountains just don’t appear in any place. Most are formed when plates, or
huge pieces of the Earth’s crust, pull and push against each other. Great
mountain ranges are formed by the movement of tectonic plates. Convection
currents deep in the mantle of the earth, begins to well up towards the
surface. As the pressure increases, it sets the crustal plates in motion.
There are different kinds of mountains - Volcanic, Folded, Fault-block, and
Dome mountains. Volcanic mountains are formed when magma comes up
through cracks in the Earth’s crust and explodes out lava and ash. The
Hawaiian volcanoes, Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens are
examples of volcanic mountains. Rocks are hard but in time they can bend or
fold producing Folded mountains. The Alps formed as the Eurasian plate
pushed against the African plate. Other examples of folded mountains are the
Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are
formed when one plate pushes...
