Tectonic plates might consist of continental lithosphere on
     Tectonic plates might consist of ______.  continental lithosphere only  either oceanic or continental lithosphere, but not both  oceanic lithosphere only  oceanic or continental lithosphere or a combination of both  Heat transfer that occurs through the movement of a fluid, driven by temperature differences among various points within the fluid is  _______  adhesion  conduction  convection  radiation 
  
  Solution
9) Tectonic lithosphere plates consist of lithospheric mantle overlain by either or both of two types of crustal material: oceanic crust and continental crust .
hence option d is correct.
10) Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Convection above a hot surface occurs because hot air expands, becomes less dense, and rises.
Hence option c is correct
