Explore the forces behind the shaping of our planet with the fascinating Earth's Dynamic Crust map. Half of a two-map set published in August 1985, this map was accompanied by "The Shaping of a Continent: North America's Active West" map and the article "Our Restless Planet Earth." This map explains the various forms of tectonic activity such as hot spots, accretion, subduction, and spreading, and includes the locations of volcanoes and the earthquakes of 6.0 magnitude or greater which occurred from 1975-1985.The 1985 Earth's Dynamic Crust map features: Six inset maps showing the location of the continents from 540 million years ago to the present Insets illustrating and explaining spreading, subduction, collision, faulting, accretion, and hot spots Active tectonic features including trenches, faults, spreading ridges, hot spots, and selected volcanoes Earthquake epicenters of 6.0 magnitude or greater that occurred from 1975-1985 Land heights and water depths An abundance of notes Plate motion noted in mm/yearCoverage Area: The WorldExplore the forces behind the shaping of our planet with the fascinating Earth's Dynamic Crust map.
