An earthquake is the phenomenon that a huge energy suddenly released and appeared in the Earth’s crust when two moved plates slip past one another. The earthquakes usually happen in the convergent boundaries, divergent boundaries and transform boundaries. In the three kinds of boundaries, the convergent boundary often produces the largest magnitude earthquakes. Because when the two plates collide strongly in the convergent boundary, the extreme pressure and the great friction will appear. So the…

The plate tectonic theory was developed in the 1960’s and it is extremely important to have a fond understanding of as it is an explanation of the amazing scientific feats that have happened and are still happening in our world today. For example, it explains why the land we stand on is in its place, how volcanoes, tsunamis and mountains are formed and many more scientific phenomenon. This theory is that the outer shell of Earth is separated into multiple plates, which are floating on the mantle…

karen Plate Tectonics There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth…

INTRODUCTION The science of magneto hydrodynamics (MHD) deals with geophysical, astrophysical and engineering problems since many years. This subject has attracted attention of many researchers in the MHD flow on Newtonian fluids on plate, cones and disks. Hari R [30] investigated the chemical and radiation effects on MHD casson fluid flow past an oscillating vertical plate embedded in porous medium. Subbaiah Naidu [70] studied the effect of Hall current on free convective flow of stratified…

GEOTHERMAL ENERGY 1.1 INTRODUCTION AND DEFINITION Geothermal energy is the utilization of heat present in the deep earth for the purpose of power generation or other direct use application. In general terms, geothermal energy consists of the thermal energy present in the Earth’s crust. Thermal energy in the earth is distributed between the constituent host rock and the natural fluid that is contained in its fractures and pores at temperatures above ambient levels. Globally, the most commonly…

It is important to acknowledge that without the critical state, interesting phenomena cannot occur. The non-critical state is at equilibrium, where Gibb’s free energy is equal to zero, and there are no avalanches. Therefore, the critical state is not at equilibrium, this is only an illusion society sees as a result of the nature of self-organized critical systems. During the intermittent periods between avalanches, society cannot detect any changes, so it is assumed that nothing is happening,…

SOILS AND EARTHQUAKE DAMAGE Create a Google Doc titled “Soil Types and the Danger of Earthquakes”. At the top of the page include your full name, period, and date. Place the assignment title underneath. Then use the links provided to answer the accompanying prompts using not less than five sentences each. Use 12 or 14 pt. Arial font and organize your answers into four distinct sections corresponding to each prompt. Add graphics if you wish, just keep them reasonable in size. Your…

Precambrian time covers the tremendous greater part of the Earth's history, beginning with the planet's creation around 4.5 billion years prior and finishing with the development of complex, multi celled life-shapes very nearly four billion years after the fact. The Precambrian is the most punctual of the geologic ages, which are set apart by various layers of sedimentary rock. Set down over a huge number of years, these stone layers contain a lasting record of the Earth's past, including the…

Seismologist with the United States Geological Survey are usually the first to arrive in volcanic areas, to predict volcanoes eruptions and to alert people so they can get evacuated safely. One problem with the predictions is that the size and direction can’t be predicted. With the new technology and equipment, it's becoming easier to predict volcano eruptions correctly. In 1991 Mount Pinatubo in the Philippines erupted causing many tribes to evacuate their homes. Researchers from the…

To begin there is one piece of crucial information that being;What is is a Fault line? A fault line is a crack in the Earth's crust in which pressure is created in the form of friction, once the rocks break under the pressure a jolt of energy released is and resulting earthquake occurs. Energy released from these geologic phenomenon are measured in a machine called a Richter Scale. The Richter Scale measures seismic waves through the ground after the initial shock in the epicenter of the…
