Question 9 • 2026 Summer 305 CR_2002040-M/J Comprehensive Science 1
Convection is the transfer of thermal energy through the movement of a fluid, so it occurs in liquids and gases, not solids. Convection currents continue while temperature differences cause parts of the fluid to move and transfer heat; they stop once the fluid reaches the same temperature throughout. Thus, B, C, and E are correct.
