THE WORLD MAP  AND  TECTONIC PLATES   PHOEBE MARIE BOHOL 10-DILIGENCE Maps of the world usually concentrate on either political or physical elements. Territorial boundaries and human settlement are highlighted on political maps. Mountain ranges, soil types, and land use are all depicted on physical maps. Not just the surface, but also the underlying rock, fault lines, and subterranean formations are depicted on geological maps. Color hue and intensity are used in choropleth maps to contrast disparities across regions, such as demographic or economic data. The many projections of the planet represent a variety of technical and aesthetic objectives for globe maps. World maps are also unique in that they require worldwide knowledge to create. Before the European Renaissance, no useful map of the world could be made because no culture knew more than half of the planet's coastlines, let alone its interior areas.  Since then, new information about the earth's surface has been collect

Three Types of Plates Tectonics PHOEBE MARIE BOHOL  10-DILIGENCE Earthquakes, volcanic activity, mountain-building and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometers to a few hundred kilometers.  In the theory of plate tectonics, a   boundary between two or more plates.  The plates can be moving toward each other (at convergent plate boundaries), away from each other (at divergent plate boundaries), or past each other (at transform faults ). A. DIVERGENT PLATE BOUNDARIES Divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate. A mid-ocean ridge usually originates in a continental plate as a rift zone that expands to the point of splitting the plate apart, with seawater fill
