Mountains are formed in many ways, two of which are
1. Fold mountains - Fold mountains are formed when two tectonic plates run into each other or collide. The force of the two plates running into each other causes the Earth's crust to crumple and fold.
2. Volcanoes - A volcano is a mountain from where the molten rocks or magma erupt through the surface. In simple terms, a volcano is an opening in the earth's surface from which the molten rocks and gases escape out. Once the magma erupts through the Earth's surface, it is called lava.
Today we decided to make our own volcano using some simple household items. For more details check out sciencebob.com/make-your-own-volcano/.
