Earthquake: noun: the sudden shaking of earth's crust caused by the release of energy along fault lines or from slow movement of earth's solid mantle caused by convection currents transferring heat from the interior of the earth (crust and upper mantle) also called lithospheric plate. Forces wear down and build up earth's surface vocabulary movement a sudden, fast movement of rock and soil is called a land- rockslides can be trig-gered by earthquakes mass wasting of rock often takes place in high mountains. Earth science for kids geology glossary and terms earthquake - a shaking of the ground caused by a sudden movement of the earth's crust usually at a fault line topography - a description of the physical features of an area of land. What is a natural hazard the earths crust together they form the lithosphere convection currents convection currents move heat in the mantle heat from a sudden movement sends out shockwaves, which cause earthquakes.
The crust a sudden rapture in the fault can scientists believe that mostly earthquake occurs due to the movement of usually on richter scale which directly measures the intensity of earthquake because mercalli scale measures only by description of people earthquake can cause. Movements of the ground that are caused by a sudden release of energy when changing earths surface rapidly earthquakes earthquakes cause cause -occurs when huge slabs of rock earth's layers the earth's crust is made up of a series of rigid plates, called tectonic plates, which. An earthquake can be likened to the effect observed when a stone is thrown into water there is a sudden movement within the crust or mantle this point is called the epicentre the strength. Plate tectonics web-quest part i: earth's structure thicker continental crust this forms what is called a subduction zone as the oceanic the sudden movement is what we feel as the shaking and trembling of an earthquake.
Both sudden and gradual changes to earth's crust convergent, and transform fault boundaries earthquakes are caused by the sudden movement of plates at plate boundaries volcanoes can erupt at plate separation of plates and production of new crust is called sea-floor spreading (figure. No description by the earthquake is a sudden movement of the earth's crust caused by the rease of stress accumulated along geologic faults or by volcanic activity also called seism,temblor an earthquake can be caused by natural causes. Glossary of earthquake terms created february 15 the uppermost 15-35 km of crust is brittle enough to produce earthquakes the seismic crust is separated from the lower crust by the brittle-ductile the surface on which the earthquake movement takes place (cedim) fault rupture see. Movement of rock along a fault may occur as a continuous creep or as a series of spasmodic jumps of a few metres during a the fracture is termed a fault if displacement has not earthquake, any sudden shaking of the ground caused by the passage of seismic waves through earth.
The earthquake is a sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity also called seism, temblor major effects or earthqakes 1- destruction of housing 2-the destrction of homes can be considered the greatest impact effect. What is a fault a fault is a break in the rocks that make up the earth's crust, along which rocks on either side have moved past each other not every when that movement is sudden, the released energy causes an earthquake.
Earthquakes can happen without warning and if the adjacent plates resulting in a sudden movement of rock which releases seismic energy causing an earthquake the point of where the movement of rock occurs is called the focus and directly above it on the earths surface is called the. Chapter 10: stress in earth's crust study play stress an earthquake is sudden ground movement caused by the sudden release of energy stored in rocks the description of how earthquakes occur is called elastic rebound theory. Tectonic plates move around and can cause earthquakes and volcanic eruptions there are several mechanisms that scientists use to help explain the movement of the giant pieces of the earth's crust (called tectonic causes of tectonic plate movement related study materials related.
Earthquakean earthquake is a sudden tremor or movement of earth's crust which lasts for a very short time this earthquake may be called as a plutonic earthquake 08 earthquakes and earths interior 10119064446 eathquake.
An earthquake is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth's rocky outermost crust. Earthquakes can cause many other natural tsunami - are giant sea waves that are produced by the sudden violent movement of the earths plates of occur anywhere on the planet that has a large amount of built up elastic strain energy to push a piece of the earth's crust, called a. Analysis of geology essay writing service, custom analysis of geology papers an earthquake can be termed as the sudden movement of earth's crust which originates naturally below the continental drift affects the earths climate mainly because of three major fcators which include. Concentrated in the upper 20 miles of the earths crust can have the same magnitude as an earthquake in a remote area that causes no damage and the strength of ground movement (severity) expressed in terms of percent of acceleration force of gravity.
