BUILDING
MOUNTAIN
Rounded mountains are called domes. Sometimes the crust does not fold or crack. Sometimes magma pushes through the vent in a solid rock form. It collects as a magma pocket under the crust. The pocket of the magma grows bigger till it bends the crust. When this happens a high dome is formed rain and wind and ice wash away the softer rocks above then rounded hills and valleys are formed.
Some shoot magma through the top those are called volcanoes. Once,in a while a small crack forms in the lithosphere. Red hot magma pushes up through the crack, lava and ashbulid up around the crack making it higher that’s how a cone shaped volcano is made.
Mountains that have flat tops are called fault-block. In other places pressure deep within the earth pulls and stretches the crust. The stretching sometimes causes long cracks or fault lines to cut though the crust. The crust on a side of a crack might move slowly upward. While the crust on the other side pushes down. Block-shaped mountains are formed this way
Pointy mountains are called folded. Folded mountains are made by two plates press up against each other and the tremendous pressure forces the crust to lift and fold. Many great waves of rocks are pushed up against each other. They make sharp mountains.
