Interior of the Earth - an introductory guide to what is known about the interior of our planet

This Dynamic Earth: the Story of Plate Tectonics - covers all aspects of the Plate Tectonics and Earth's Structure", many of the illustrations and content focus on plate tectonic forces that are shaping the west coast of North America. It covers the history of the developing theory of Plate Tectonics through exploration of the sea floor and discoveries that supported understand modern understanding of the dynamics of the Earth's interior and the formation, migration, and destruction of great crustal plate; see companion This Dynamic Planet map listed below

'Ring of Fire', Plate Tectonics, Sea-Floor Spreading, Subduction Zones, 'Hot Spots' - about plate tectonics and volcanic eruptions including the geology behind the Cascade Range Volcanoes, the East Africa Rift, the Iceland volcanic rift, the Juan De Fuca Ridge and Juan de Fuca Subduction Zone, the Marianas Trench, the Mid-Atlantic Ridge, South America, and the Hawaiian and Yellowstone "hot spots."
