This is the movement of Earth's continents, relative to each other, due to plate tectonics.
For more general info on tectonic plate see the video below.

This is the movement of Earth's continents, relative to each other, due to plate tectonics. Create, edit and share any type of classroom activity with ease. You must be logged in to report an error. The mechanism of the tectonic plate movement has been the debate among the Earth scientists. This refers to the geological processes, mostly large-scale movements of Earth's crust, that result in the formation of mountains. Diagram credit: Jean Anastasia Within the atmosphere and oceans, they drive winds and weather patterns. • The lithosphere is broken up into separate plates, which include continents and ocean basins.

continental plates collide and push up creating mountain ranges, High heat flow, volcanoes, and earthquakes, A vent or fissure in the Earth's surface through which magma and gases are expelled. Write a review to help other teachers and parents like yourself. Continental Drift. This is the geologic theory where the cooler surface of the earth move slowly over the hotter layer underneath. Save 50% Now. For example the North America and South America plates. The process repeats, creating a convection cell pattern in the mantle which causes tectonic plates movement. Key concepts include: the lithosphere and the asthenosphere; "plates"; convection; the observation that the most active geology takes place on plate boundaries; and the Wilson Cycle, a concept that describes lifecycles of oceans and continents. Plate Tectonics Articles, Theory, Plate Diagrams, Maps, Teaching Ideas. Details about the diagram include: The two tectonic plates that lie under the Atlantic Ocean are the Eurasion and African Plates. This can lead to earthquakes. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

Plate tectonics is a theory about how Earth's lithosphere is divided into a series of rigid plates; and, how movements of these plates produce earthquakes, volcanoes, ocean … Claim 50% … This is a portion of the Earth's surface that may be far from tectonic plate boundaries, yet experiences volcanism due to a rising mantle plume or some other cause.

Proposed the continental drift theory in the 1900s, term for the super continent which contained all the plates together, The thin and solid outermost layer of the Earth above the mantle, The solid, outer layer of the Earth that consists of the the crust and the rigid upper part of the mantle, The soft layer of the mantle on which the tectonic plates move, The boundary between tectonic plates that are sliding past each other horizontally, The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations, The process by which new oceanic crust forms as magma rises towards the surface and solidifies, long, narrow depression formed at divergent boundaries, process in which two plates collide and the thinner oceanic plate moves beneath the continental plate, circular movement of heat within Earth which drive the movement of tectonic plates, Fossils, climate, rocks, glacial deposits, extremely deep areas in the ocean that are created by a subducting plate, where the Earth's crust is thin so magma is able to break through the surface, forming volcanoes Example: Hawaiian Islands, an underwater mountain range made at divergent plate boundaries, a sudden or violent movement within the Earth's crust followed by a series of shocks, the low density, thick outer layer of Earth which forms our continents, a hot, dense layer of Earth found between the crust and core, the dense, thin outer layer of Earth that lies underneath the ocean, section of the Earth's crust about 100km thick, A major belt of volcanoes that rims the Pacific Ocean.

A divergent boundary occurs when two tectonic plates move away from each other.

The outermost part of Earth's structure is known as the lithosphere.

Earthquake - Tectonic Plates Geology Diagram Poster. Add. Tectonic Plate Diagram. This cycle of heating and cooling is called a convection current. The lithosphere consists of the crust and small portion of the upper mantle. The ocean and continental lithosphere and the asthenosphere (Diagram by Phyllis Newbill). Tectonic plates are part of the earths outer layer. Key concepts include: the lithosphere and the asthenosphere; "plates"; convection; the observation that the most active geology takes place on plate boundaries; and the Wilson Cycle, a concept that describes lifecycles of oceans and continents.
