In this type of heat transfer fluid particles move from on location to another carrying energy with them.
Convection
In this type of heat transfer energy moves from atom to atom, but the atoms themselves stay in place.
Conduction
Radiation is energy in the form of ________.
Light
________ _________ colored material absorbs more energy than _______ colored material.
Dark, dull, light

Formed when plates collide.
Convergent
Form along boundaries that exist as cracks, or faults
Transform boundaries
