what is the reason behind earth quake.?

Question

natural disaster

Answer 1

earthquakes occur when the tectonic plates that cover the earth noticably shift. These movements can also form volcanoes and trenches

Answer 2

The earth's surface is moving all the time. When there is a major plate drift or shift, we have earth quakes. Volcanic activity under the crust can cause shifting. I believe that kind of activity has increased 100 fold since 1990. Check with http://earthquake.usgs.gov You can sign up to get updates of earthquakes all over the globe each day.

Answer 3

Earthquakes occur when one mass of rock suddenly moves in relation to another. The movement does not have to be very great to cause severe destruction in cities.
Many earthquakes occur in the same regions as VOLCANOES. This is explained by CONTINENTAL DRIFT. Great strain results where two plates are colliding or moving past each other.Pressure builds up between masses of rock ad then they suddenly give way and move, causing earthquakes. The split produced where rocks break under such presure is called a fault.

If molten rock lies underneath, vents may open up and lava will appear on the surface.

When an earthquake occurs beneath the sea, a tsunami is created.

Answer 4

Living in California has overwelmed me with a constant flow of what causes earthquakes. The surface of the earth is like a puzzle floating on a semi liquid sub surface as the edges of these plates either rub along each other or dive over and under they do not do it smoothly. Some times as this happens the are3 stuck then as the move again this is the sudden jolt as the constant pressure is aleays building up.

Answer 5

Our planet Earth is made up of different layers - we live on the crust! underneath the crust are the tectonic plates. There are several plates. they cover the entire palent. under these plates is a sea of molten rock. this sea is constantly moving. sometimes the plates slide alongside each other. this is much like grinding your teeth very hard together. the plates grind together which causes the ground to shake - hence - an earth quake! Happy?

Answer 6

Plate techtonics explains this. The earth consists of "plates" that are constantly shifting and creating instability. If you look at a map of Africa and South America, you can see how one continent moved far from the other. Where there are faults, such as the San Andreas Fault in California, stress could cause movement and a major earthquake.

Answer 7

REASONS BEHIND THE EARTH QUAKE IS SIMPLY CAUSED BY THE PEOPLE GOING TO THE MOON FOR RESEARCH OF SOMETHING THAT IS NOT LOST. IN AFRICA, THERE IS NOTHING CALLED EARTH QUAKE, IT IS ALL YEAR ROUND PERFECT WEATHER, SO IF THEY CAN STOP ALL THESE RESEARCHES, THEN THE COUNTRY WILL BE A BETTER PLACE FOR ME AND YOU TO LIVE AND DINE.

Answer 8

an earth quake is when 2 tectonic plates intersect and start to grind against each other, causing the ground to rumble

Answer 9

For plate barriers, the plates are shifting against one yet another, and in some circumstances the sides of them get hung up and stick. Earthquakes ensue whilst the section that sticks unexpectedly strikes. it fairly is like taking 2 products of one million/2-dried out Play dough or clay and shifting them previous on yet another. a number of it strikes easily, yet a number of it catches on one yet another so which you should push tougher to make it flow. For mountains, that's a controversy of uplift and weathering. Mountains are like ice bergs - part of them stick up above the floor, yet there's a super variety of it which you do no longer see it fairly is underground. As they slowly erode down because of the fact of rain, snow, and wind, they upward thrust up because of the fact they are floating on a sea of magma. So the stresses of uplift motives the mountains to crack and shift, and those reason earthquakes. in case you pay attention to ice melting in a tumbler of water, you pays attention the cracking and transferring. it fairly is an identical with mountains. clearly shaped ice is seen a sort of rock, you comprehend. So it stands to reason that it would act in addition.

Answer 10

earth quakes are caused by the crack in the earth surface, one sliding under the other therefore causing fraction that causes the earth to shake as it passes. the raise of one crack is cause by pressure from the earth center core expanding.
