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.
Two Oceanic Plates-When two oceanic plates collide, one may be pushed under the other and magma from the mantle rises, forming volcanoes in the vicinity. Two Continental Plates-When two continental plates collide, mountain ranges are created as the colliding crust is compressed and pushed upwards.
