Question

3 multiple choice 1 point ______ is the movement of matter that results from differences in density caused by variations in temperature radiation conduction convection evaporation

Explanation:

• Radiation is the transfer of energy via electromagnetic waves, no matter movement.
• Conduction is heat transfer through direct contact of particles, no bulk matter movement.
• Convection involves the movement of matter (fluids, usually) due to density differences from temperature changes (warmer, less dense matter rises; cooler, denser matter sinks).
• Evaporation is the change of liquid to gas at the surface, not about bulk matter movement from density/temperature differences.

Answer:

C. convection
