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.
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.
