  1. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati-Benioff zone. These collisions happen on scales of millions to tens of millions of years and.
  2. Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system. CONDUCTION- -. Conduction is the transfer of heat between.
  3. Convective Heat Transfer Coefficient.
