  2. Vibration of plates - Wikipedia

    en.wikipedia.org/wiki/Vibration_of_plates

    Vibration mode of a clamped square plate. The vibration of plates is a special case of the more general problem of mechanical vibrations.The equations governing the motion of plates are simpler than those for general three-dimensional objects because one of the dimensions of a plate is much smaller than the other two.

  3. List of tectonic plate interactions - Wikipedia

    Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]

  4. List of tectonic plates - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plates

    These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km 2 . Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere ) like the Apulian ...

    en.wikipedia.org/wiki/Cymatics

    Resonance made visible with black seeds on a harpsichord soundboard Cornstarch and water solution under the influence of sine wave vibration A demonstration of sand forming cymatic patterns on a metal plate. Cymatics (from Ancient Greek: κῦμα, romanized: kŷma, lit. 'wave') is a subset of modal vibrational phenomena.

    Seismic waves are vibrations that travel through the Earth's interior or along its surface. [17] The entire Earth can also oscillate in forms that are called normal modes or free oscillations of the Earth. Ground motions from waves or normal modes are measured using seismographs. If the waves come from a localized source such as an earthquake ...

  7. Plate theory - Wikipedia

    en.wikipedia.org/wiki/Plate_theory

    Vibration mode of a clamped square plate In continuum mechanics , plate theories are mathematical descriptions of the mechanics of flat plates that draw on the theory of beams . Plates are defined as plane structural elements with a small thickness compared to the planar dimensions. [ 1 ]

  8. Tectonic uplift - Wikipedia

    en.wikipedia.org/wiki/Tectonic_uplift

    The Pamir Mountains, Tian Shan, Altai, Hindu Kush, and other mountain belts are all examples of mountain ranges formed in response to the collision of the Indian with the Eurasian plate. The Ozark Plateau is a broad uplifted area which resulted from the Permian Ouachita Orogeny to the south in the states of Arkansas , Oklahoma , and Texas .

  9. Geodynamics - Wikipedia

    en.wikipedia.org/wiki/Geodynamics

    Geodynamics is a subfield of geophysics dealing with dynamics of the Earth.It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting.
