Three types of plate boundary • Divergent • Convergent • Transform Divergent Boundaries • Spreading ridges – As plates move apart new material is erupted to fill the gap Age of Oceanic Crust Courtesy of www.ngdc.noaa.gov Iceland: An example of continental rifting • Iceland has a divergent plate boundary running through its middle

to 10cm per year. There are three types of boundaries and they are the divergent‚ convergent and transform boundaries. Plates‚ Boundaries and Zones There are about 30 different plates that glide along the mantle. There are three plate boundaries‚ they are the divergent plate boundaries‚ transform plate boundaries and the convergent plate boundaries. Divergent plates move away from each other and are found in the middle of major oceans. These boundaries help to form underwater volcanoes and create

Plate Tectonics Plate tectonics is the science and study of causes and relative motions of earth’s lithosphere plates. This theory proposes that earth’s outer layer is made up of plates which have moved throughout earth’s history. It is the scientific theory that attempts to explain the movements of the Earth’s lithosphere that have formed the landscape features seen across the world today. The primary natural hazards facing the islands of the Caribbean are earthquakes and hurricanes. Some of the

in them: the North American‚ South American‚ Eurasian‚ African‚ Indo-Australian‚ and Antarctic. The other three are oceanic plates: the Pacific‚ Nazca‚ and Cocos. There are 3 primary types of Tectonic Plate boundaries: Divergent boundaries; Convergent boundaries; and Transform boundaries. As the giant plates move‚ diverging (pulling apart) or converging (coming together) along their borders‚ tremendous energies are unleashed resulting in tremors that transform Earth’s surface. While all the plates

| Lithosphere | Ecology (NASC 1093) | | The Lithosphere * The lithosphere is the hard shell of the Earth‚ consisting of the crust and the topmost part of the upper mantle. * It is a relatively thin layer‚ about 31 to 62 miles (50 to 100 km) thick under the oceans and 93 miles (150 km) thick on the continents. * It contains the minerals‚ rocks and soils that humans have used for building materials‚ metals and agriculture. * This layer is composed of the upper crust‚ about 3 miles
