Most of the world's largest earthquakes happen around the rim of the Pacific Ocean. The map below shows the locations of the 15
largest earthquakes in the world since 1900. World's 15 largest earthquakes since 1900 - located in the circum-Pacific Belt - concentrated around the coastal regions of Chile, Indonesia, japan and Alaska
Refer to the map of Earth's plates below, and determine which type of plate boundary is most often associated with these earthquake events.
The earth plates move to each other in Convergent boundaries plates. The convergent boundary plate can be ocean/ocean, ocean/continental, and continental/continental convergent boundary plate. They are also considered a destructive boundary plate because the plate constantly collides with each other.
For the ocean continental convergent boundary plate, oceans and a continental plate collide. The collision leads to subduction which is the movement of the continental plate below the ocean plate. This movement of the continental plate beneath the ocean plate can result in earthquakes
<em>From the map, most of the location affected are characterized by Ocean/ Continental convergent boundary, that is why earthquake often occurs in these locations.</em>
As the fluid is heated it rises as the molecules get energy on heating, similarly the particles cool when they are condensers at a certain temperature that causes them to sink a similar pattern is found in the atmosphere also. The light arises and heavier air falls as it's dense and hence sinks again.
Similarly, the earth heating patterns that are derived from convection currents coming from the mantel are also derived from the tectonic processes from within the earth's interior.
Within the atmosphere and oceans are also found the wind and pressure belts that rotate in the spherical motion and derive up and down from the equator of the earth. The poleward cool air and hot air from the equator are mixed and create turbulence in the upper atmosphere in the form of Jet steams and westerlies and easterlies that derive the weather patterns around the globe.
Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy. ... Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them!
