Dan McKenzie went on to further explain sea floor spreading, being able to explain why new crust was made at mid oceanic ridges. He used his knowledge of thermodynamics to come up with a model of the

He believed that all of the continents were once joined together, forming a super-continent called Pangaea. These plates are thought to float on the underlying semi-molten asthenosphere and are moved by convection currents that derive their heat from the earth's crust. It states that this process isi continous and forms new land along the boundaries where the plates move apart - known as constructive margins - and destroys older crust where the plates are moving together - destructive margins. Later evidence also supported this theory - fossilised remains of a dinosaur, the mesosaurus, were discovered on the coasts of Brazil and Gabon. Wegeners ideas were proved even further, increasing our knowledge of tectonic events.
what we can do outside of the home to help save our environment. To begin, I would like to fill you in on the important role we play in decreasing and reversing some negative effects global warming has caused. By making choices that help the reduction of greenhouse gas output into the air, global warming can be reduced or even reversed. The emission of greenhouse gases causes the Greenhouse Effect, which plays a detrimental role in the process of global warming. I will discuss what can be done to reduce the emission of greenhouse gases with you shortly.
Carbon dioxide fire extinguishers expel a cold fog of CO2 that cuts a fire off from its air supply. Dry chemical extinguishers spray a fine power that coats fuel and cuts it off from air. Foam is applied to blanket large pools of burning liquid to cut off air. You've seen foam being applied to limit or extinguish fires involving burning fuel in films and on TV, haven't you? Sure.
J. Subbiondo © 2004The CrustThe outer layer of the Earth is called the crust. It is made up of rock that floated to the surface when the Earth was formed. It is not a continuous layer, but is made up of large masses called tectonic plates.These plates drift slowly across the Earth's surface (tectonic means moving).The movement of these plates creates mountains and valleys.At weak points in the crust, it causes volcanic eruptions. And when plates bump into each other, earthquakes occur -- emitting shock waves or vibrations called seismic waves. The crust is the Earth's coldest layer.
Meteorites are naturally occurring objects that originate in space and survive a fall to the ground through Earth’s atmosphere. (What are meteorites?) Most are remnants of asteroids or possibly comets. However, a few have been shown to be pieces of Moon or Mars that were launched into space by an impact event. While moving through space these objects are known as meteoroids.
Millie Newton Miss Amiat 22 February 2018 Plate Tectonics definition of plate tectonics Plate tectonics is the study of the structure of the earths crust & mantle with reference to the theory that the earths lithosphere is divided into large rigid blocks that are floating on semi fluid rock and are thus able to interact with each other at their boundaries and to the associated theories of continental drift and sea floor spreading. There are a few handfuls of major plates and dozens of minor plates. Seven of the major plates are named for the continents, such as African, Antarctic, North American, Eurasian, Indo Australian , Pacific and South American. Plate Tectonics explains why earth quakes and volcanoes are concentrated on specific
