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.
Shield volcanoes, formed when large flows of lava spread rapidly from central vents or rows of vents, are the largest volcanoes. Because the lava moves rapidly and spreads out in a broad area, it does not form a tall, steep cone. Instead, shield volcanoes are dome-shaped mountains with broad bases and gentle slopes.tratovolcanoes. Stratovolcanoes, or composite volcanoes, get their name from the different layers, or strata, of ash and lava that form them. Most stratovolcanoes are irregularly shaped mountains formed by material ejected from both a central vent and other vents on the sides of the mountain.
