Interior of earth,

  Most of the knowledge we have about Earth’s deep interior comes from the fact that seismic waves penetrate the Earth and are recorded on the other side.  Earthquake ray paths and arrival times are more complex than illustrated in the animations, because velocity in the Earth does not simply increase with depth. Velocities generally … Read more Interior of earth,

Tsunamis

      A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water. Tsunami are sometimes called “seismic sea waves”, although they can be generated by mechanisms other than earthquakes. Tsunami have also been called “tidal waves”, but this … Read more Tsunamis

 Horizontal and vertical distribution of temperature, inversion of temperature

  The temperature is the measurement in degrees of how hot (or cold) a thing (or a place) is. The temperature of the atmosphere is not same across the Earth. It varies in spatial and temporal dimensions. The temperature of a place depends largely on the insolation received by that place. The interaction of insolation … Read more  Horizontal and vertical distribution of temperature, inversion of temperature
