The earth is made up of tectonic plates these are massive slabs of rock floating on magma ‚as the plates move about‚ they spread apart‚ collide‚ or slide past each other‚ This is the main cause of volcanoes and earthquakes Earthquakes occur in many regions all over the world in some regions they occur more frequently and severely than in others (depending on the location)‚ the main cause of earthquakes is tectonic plates grinding against each other ‚ therefore earthquakes

have to do with plate tectonics? The Ring of Fire is a direct consequence of plate tectonics and the movement and collisions of crustal plates.What does the ring of fire have to do with plate tectonics?The "Ring of Fire" refers to a string of volcanoes‚ which create a ring in the Pacific. The relevance to plate tectonics‚ is that volcanoes are created by two plates coming together and pushing up on each other to create the volcano. The Ring of Fire is evidence of high plate tectonic movement in that

Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow‚ so when the pressure becomes too great for the plates to withstand‚ one part of a plate gives way to the pressure by rising above the other part of the tectonic plate. This then causes the top plate to overlap and collide with the other plate. This

Drift Abstract The Earth is formed by plate tectonics continuously shifting causing a continental drift. This theory is more accepted than when it was originally published due to better technology providing better research and evidence. This paper discusses a little on both the plate tectonics and the continental drift as well as how the scientific method helped understand this process better. key words: Continental Drift‚ Scientific Theory‚ Plate tectonics In 1915‚ a scientist by the name

mostly occur at plate margins. They can also occur at hot spots and in rift valleys. The most active volcanic zone is the Pacific Ring of Fire around the Pacific plate. Here plates are colliding or separating. At active points on these plates volcanic mountains are formed‚ e.g. Nazca Plate and South American Plate‚ where plates separate‚ e.g. Pacific and Nazca Plate and in rift valleys‚ e.g. African Plate‚ Kenya. The most active area on the globe is the western rim of the Pacific Plate - stretching

Plate Tectonics The forces that shape the earth begin beneath the lithosphere. Rock in the asthenosphere is hot enough to flow slowly. Heated rock rises‚ moves up toward the lithosphere‚ cools and circulates downward. Riding above this circulation system are the tectonic plates‚ enormous moving pieces of the earth’s lithosphere. [pic] Plate Movement Tectonic Plates move in four different ways. When tectonic plates come into contact‚ changes on the earth’s surface occur. 1. Diveregnt Boundary-

deepest ocean trenches to the highest mountain rangers‚ plate tectonics explain all of the features from the past and present. A plate tectonic is a theory that was developed in the 1960s. According to the concept‚ Earth has a rigid layer called the lithosphere‚ which is normally 100km thick. The lithosphere is broken up into seven large continental and oceanic plates‚ six or seven medium sized regional plates‚ and various small ones. These plates do not move very far very quickly‚ and they usually slide

of natural processes that lead to the formation and transformation of igneous‚ sedimentary‚ and metamorphic rocks. The rock cycle shows that each type of rock can change in a certain way to form another. The driving force of the rock cycle is plate tectonics. The transition to igneous is when rocks are pushed deep under the earth’s surface and may melt into magma‚ if there is no condition for the magma to stay in a liquid state‚ it will cool and solidify into an igneous rock. The three main types
