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).
Another way that mountains are formed is when magma from beneath the Earthâs surface is pushed up, but doesnât actually crack through. This bulge of magma eventually cools and hardens into hard rock, like granite. The layers of softer rock above the magma erode away and youâre left with a large dome-shaped mountain.
Fold mountains are the most common type of mountains. They are formed due to collision of two plates, causing folding of the earth's crust. The fold that descends on both sides is called anticline, whereas, the fold that ascends from a common low point (on both sides) is called syncline.
