Topps has created some of the hobbyâs most iconic football cards, including almost all of those that would be on the list of the most valuable and popular ever issued. From 1956-63 Topps enjoyed a virtual football card monopoly (with the exception of 1961).
1 Volcanic mountains-Mountains that are caused by volcanic activity are called volcanic mountains. 2  There are two main types of volcanic mountains: volcanoes and dome mountains. 3  Volcanoes are formed when magma erupts all the way to the surface of the Earth. 4  The magma will harden on the Earth's surface, forming a mountain.
Fold mountains form when two tectonic plates move together (a convergent plate boundary). Fold mountains form from sedimentary rocks that accumulate along the margins of continents.When plates and the continents riding on them collide, the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak layer such as salt.he forces responsible for formation of fold mountains are called orogenic movements. The term orogenic has derived from a Greek word meaning mountain building. These forces act at tangent to the surface of the earth and are primarily a result of plate tectonics.
