they necessarily don't
Sometimes. In convergent/destructive plate boundaries, before larger earthquakes occur, the movements of the plates will result in smaller earthquakes. When the plates finally collide into each other, shockwaves will radiate out from the epicenter and cause the larger earthquake. In transform plate boundaries, the two plates rub against each other and the shockwaves causes the plates to move. Basicly the earth is made in layers, and the layers below us are made of constantly moveing plates. When two plates hit each other this will cause an earthquake. Wheather their are earthquakes after this depend on many variables, so you'd probably want to go to a professional web sight, if their a part their explaination you don't undrestand someone on wiki answers could probably help.
The UK does have frequent small earthquakes, between 100-200 are detected each year. However because it is not near a tectonic plate boundary, large damaging events are unlikely to occur.
beagles come in four sizes, small, medium, large, and then there is a mini-beagle, which is very very very small
the tectonic plates
Aftershocks
it depends on how big or small the vibration is to determine the sound. The bigger the vibration, the lower the sound is. the smaller the vibration, the higher the sound.
Foreshock is what you call one of the little earthquakes that come before the big earthquake or main shock. The main shock may be followed by a little earthquake that's called the aftershock.
when some earthquakes come they make the ground or surface of the earth uneven which sometimes form mountains
Alaska has had by far the most and biggest quakes. 9 and bigger. California and cascade zones probably come in second.
James Madison was the one who helped come to the agreement on how bigger states and smaller states should be treated. In the end both big and small states are treated equally.
Earthquakes come from shifts in tectonic plates of the earth. Some of the rifts between these are in bodies of water.
One container bigger than a boiling tube in science is a beaker. Beakers come in a variety of sizes and are used to hold and heat liquids during experiments.
