subduction

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

Orogenic or the mountain-forming movements

  Orogenic or the mountain-forming movements act tangentially to the earth surface, as in Plate tectonics. Tensions produces fissures (since this type of force acts away from a point in two directions) and compression produces folds (because this type of force acts towards a point from two or more directions). In the Landforms so produced, … Read more
