Energy and Earthquakes etc.

Where does the energy come from that creates earthquakes and causes volcanoes to erupt?  Is this energy similar to the energy of a meteor impact?

  1. The Earth's internal heat source provides the energy for our dynamic planet, supplying it with the driving force for plate-tectonic motion, and for on-going catastrophic events such as earthquakes and volcanic eruptions. This internal heat energy was much greater in the early stages of the Earth than it is today, having accumulated rapidly by heat conversion associated with three separate processes, all of which were most intense during the first few hundred thousand years of the Earth's history: (1) extraterrestrial impacts, (2) gravitational contraction of the Earth's interior, and (3) the radioactive decay of unstable isotopes.

  2. What Causes Volcanoes?

    To understand what causes volcanoes, you need to understand how the earth is made up. The earth has three main layers: the crust, the mantle and the core. The crust is made up of solid rock and varies in thickness. It is more than 60km thick under mountain chains like the Alps and Himalayas, but just 5km under the oceans. The mantle is a thick layer of molten rock (called magma), and the core is made up of an outer liquid layer and a solid centre.

    Temperatures inside the earth are very high – over 5000’C in the core. This means that the planet on which we live is like a huge fiery ball of hot molten rock, surrounded by a few kilometers of relatively cool, hard rock – the crust. Because heat rises, the magma in the earth’s mantle has to find a way to rise upwards though the crust above it, rather like the way that hot air rises.

  3. The energy comes from the Earth's crust and solid brittle upper mantle together form the lithosphere. This behaves as a brittle solid. This means that when the strength of this layer is exceeded it fractures or breaks apart into separate or discrete blocks. These very large blocks are known as tectonic plates. No it is not similar to meteor impact.

  4. The energy comes from the Tectonic Plates below the earths surface.Meteors when they ht earth use KINETIC ENERGY which would be equivalent to a 12.4 on the richter scale.So no they dont use the same energy

  6. The energy comes from pressure from the Earths crust. No the energy isn't the same.

  7. The energy that creates earthquakes comes from the faults moving. This energy is created when the the faults move thus causing the earthquake. I guess this energy dose cause volcanos to erupt but i'm not sure

  10. THe eneregy is from plates smashing together and meteors come from outside the earth.

  14. The idea that a changing climate can persuade the ground to shake, volcanoes to rumble, and tsunamis to crash on to unsuspecting coastlines seems, at first, to be bordering on the insane. http://www.motherjones.com/environment/2012/02/climate-change-linked-to-volcano-eruptions-earthquakes

  15. Heat of the core of the Earth. The meteorites are from outside of the Earth so it may be different. But the same force may cause some of them........

  17. Tectonic plates move to cause earthquakes and meteors come into the Earths atmoshere.

  18. The Energy comes from the inside of earth and or meteors bringing it to Earth as it crashes.

    1. They are different by the ratio and they same by the impact they cause

  22. It comes from the heat of Earth's core. I'm not sure if the energy is similar, but I'm guessing that it probably isn't.

  24. The energy that creates Earthquakes comes from the Tectonic Plates, so no, they don't use the same energy because meteors aren't caused because of the Tectonic Plates.

  25. The energy comes from the heat of the core in the earth, and the plates rubbing together making waves. The energy isn't the same as if a meteor were plummeting to earth, because the energy comes from no gravity in space.

  27. The energy comes from when plates hit together and cause an earthquake.

  28. No the power comes from the core of the earth and when the plates move it releases some energy witch makes earthquakes.

  35. the energy that creates volcanos is from the heat in the earth. Also from plates in the ground moving and making energy.

  39. Earthquakes occur when energy stored in elastically strained rocks is suddenly released. This release of energy causes intense ground shaking in the area near the source of the earthquake and sends waves of elastic energy, called seismic waves, throughout the Earth. Earthquakes can be generated by bomb blasts, volcanic eruptions, sudden volume changes in minerals, and sudden slippage along faults. Earthquakes are definitely a geologic hazard for those living in earthquake prone areas, but the seismic waves generated by earthquakes are invaluable for studying the interior of the Earth. No the impact is not the same.

  40. The energy comes from the the heat in the core of the earth that is transported to the tectonic plates. Where if the tectonic plates cannot store any more energy it then breaks and rumbles through the rock.

  43. The earth's crust is made up of many tectonic plates which are slowly moving. When two tectonic plates clash, rub, or separate, this can cause an earthquake. A volcano is caused by a build up of magma under the earth's crust.
