Tectonic Plates Oceanic Crust
1,370 wordsThe core is divided into two parts, the solid inner core and the liquid outer core. The inner core is thought to be solid and primarily made up of iron and some nickel. The outer core is all around the inner core and is believed to be made up of liquid iron mixed with liquid nickel. The outer core is about 2890 to 5100 km. The inner core is 5100 to 6378 km. Earths mantle is mainly composed of substances high in iron and magnesium. The melting point of every substance depends on the pressure and ...

Millions Of Dollars Plate Tectonics
1,068 wordsEARTHQUAKE REFERENCE FILES Earthquake, shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they create is called seismology. Scientists who study earthquakes are called seismologists. (Webster's p. 423) The destruction an earthquake ...

Shield Volcanoes Plate Tectonics
1,406 wordsWhen there is a sudden breaking of rocks within the earth or an explosion, wave like energy travels through the earth and is recorded on seismographs. These are called seismic waves and they are of two types: body waves and surface waves categorized into different kinds. What we will be discussing are body waves; there are two types of body waves: primary waves (P waves) and secondary waves (S waves). Both kinds travel through the Earths interior in all directions and arrive before the surface w...

Evidence To Support Continental Drift
1,020 wordsWe live in an extraordinary era of exploration. We are now able to reach far out into space and deep down into the ocean. We have the advantage with technology such as computers and satellites. We can now simply understand the dynamic forces that shape our Earth. Our Earth is constantly destructing and recreating. It balances through a continuous rebirth cycle. The Earth? s dynamic shape can be summed up very simply-Transfer Of Energy. This " Big Idea" helps to explain many things such...

The earth can be divided into concentric layers. These can be distinguished from one another through varying chemical composition, temperature, density and phase. The inner most central body is called the core. This consists of two parts: the inner and outer core. The inner is understood to be solid due to the immense pressures, and the outer core...

Oceanic Crust Igneous Rocks
1,525 wordsI. INTRODUCTION A mountain is an elevated land mass usually higher than its surroundings. Some are isolated, but they usually appear in ranges (Ms Bs 95 W 32). A group of ranges closely related in form, origin, and alignment is a mountain system; an elongated group of systems is a chain; and a complex of ranges, systems, and chains continental in extent is a cordillera, zone, or belt. (Ms Bs 95 W 32). Some mountains are remains of plateaus, mesas, and buttes, through erosion (Summerfield). Other...

Oceanic Crust Continental Drift
780 wordsPlate tectonics are a relatively new theory that has revolutionized the way geologists think about the Earth. According to the theory, the surface of the Earth is broken into large plates. The size and position of these plates change over time. The hypothesis of continental drift was largely developed by the German Alfred Wegener The edges of these plates, where they move against each other, are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain building. Plate tect...

Plate Tectonics Paradigm Shift
1,310 wordsWhen Albert Einstein proposed his Theory of Relativity it was not accepted immediately but eventually over time and after some debate it became a replacement for the idea of physical mechanics formulated by Isaac Newton to explain the motion of large bodies in the presence of gravity. Relativity did not totally discredit Newtonian Mechanics but it did raise new questions and could prove certain things that Newton could not. There were questions, critics, and proponents of the new idea but it cam...

Time It Takes Surface Of Mars
2,185 wordsMars is the fourth planet from the sun and orbits the sun at a distance of about 141 million mi. Mars is named for the Roman god of war because it appears fiery red in the earth? s night sky. Mars is a small planet that has about half the diameter of Earth and about one-tenth Earth? s mass. The force of gravity on the surface of Mars is about one-third of that on Earth. Mars has twice the diameter and twice the surface gravity of Earth? s moon. The surface area of Mars is almost exactly the same...

Plate Tectonics Ocean Basins
530 wordsPlate Tectonics is theory of global tectonics (geologic structural deformations) that has served as a master key in modern geology for understanding the structure, history, and dynamics of the earths crust. The theory is based on the observation that the earths solid crust is broken up into about a dozen semirigid plates. The boundaries of these plates are zones of tectonic activity, where earthquakes and volcanic eruptions tend to occur. Plate Tectonics also are the cause of major features that...

Million Years Ago 000 Years Ago
648 wordsThe Evolution of Lake Champlain Basin A billion years ago, Lake Champlain and all of North America was covered by huge glaciers. The air was rich in oxygen because of photosynthesis done by plants. The Adirondacks Mountains Mountain-building events made the then 20, 000 feet Adirondack Mountains. Minerals such as garnet, anorthosite, and diopside came from metamorphic rocks. The Iapetus Ocean What is now the Champlain Valley started to rift 600 million years ago. It turned into the Iapetus Ocean...
