seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the crust to become mobile which creates the different types plate margins‚ makes the cause due to physical factors. However human activity

Movement Essay Continental Drift is the idea that refers to the movement of Earth’s continents and plates relative to each other. This means that the earth’s plates move because of the unending cycle of cooling and raising of molten rock‚ adding new material t0 the edges of the plates. This movement is called divergent movement‚ the most common of the three types of movement between plates. The other two movements are called convergent and transform-fault. This idea was first suggested by

Over 13.5 billions years ago‚ a gigantic explosion produce energy and fundamental particle that created the universe. This mean that all the things that we see today such as rock‚ animal‚ plant‚ water was created during that time. First‚ quark is formed which is proton

chain of waves. The main cause of tsunamis are submarine earthquakes. These are most common at subduction zones. Friction between subducting plates causes a build-up of pressure‚ eventually this pressure is released causing an earthquake. These submarine earthquakes can displace huge volumes of water. On the 26th December 2004 at the Indian plate/ Burma plate subduction zone‚ lots of pressure was suddenly released north-west of the coast of Sumatra‚ resulting in a megathrust earthquake of 9.1 on the

“Eat some more food.” Everyone surrounding me was telling me to eat more and more. Aunties‚ uncles‚ and cousins that I never even knew I had were telling me to eat. Even though I was already full‚ I picked up another plate and started to eat again. Every time I go to a Filipino party‚ I find myself eating more and more. Growing up Filipino‚ I have always been accustomed to going to a big Filipino family party at least once a month. Usually‚ my family would all get together at an auntie or uncles

rise and fall within the mantle‚ the crust breaks up into large pieces‚ called plates‚ which move about very slowly on earth’s surface. The movement of the plates creates powerful forces that continually create and destroy land features and reshape the earth’s surface. Most of the action takes place at the plate edges‚ or boundaries‚ where plates move against or over each other‚ or dive back below the surface. As the plates move‚ mountains are uplifted‚ the sea floor cracks and spreads‚ volcanoes erupt

Houston‚ Seattle‚ and San Francisco have all experienced a fault shift. In the case of Houston‚ the likelihood of an earthquake is extremely low. The instances of a fault shift on that area of the North American Plate don’t occur often. Earthquakes that occur are not by normal means of plates shifting but from the process of fluid extraction (Fehling 19). Seattle on the other hand has a very high probability of an earthquake occurring. There are three different types of quakes that the city experiences
