Question 139947 • PARTA - EOP: PGCPS BIOGEOCHEM CR (FALL2026) - 798113

Which statement describes the principles on which tidal energy works?

Answer
A
Kinetic energy in the motion of water is converted to electricity.
B
Potential energy in the motion of water is converted to electricity.
C
Chemical energy from salt water is converted to electricity.
D
Mechanical energy from water is converted into electricity.

Explanation

Tides create moving currents of water. Turbines capture the kinetic energy of that moving water and convert it into electrical energy, so the correct statement is “Kinetic energy in the motion of water is converted to electricity.” Potential energy is stored energy, not the energy directly described here.
