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.
Most mountains form at places where the Earth's plates move towards one another and the planet's crust is subjected to immense forces. For example, the Himalayas formed when the Indo-Australian plate and the Eurasian plate collided. As one plate moved below the other, what is modern day India and central Asia came together and were forced upwards creating 'fold mountains'.
