I WONDER - What Is Ocean Energy?

The video tutorial discusses three main types of ocean energy: wave energy, tidal energy, and ocean thermal energy conversion (OTEC). Wave energy is derived from the surface waves of the sea, tidal energy is generated from the rise and fall of tides due to the gravitational pull of the moon and the sun, and OTEC utilizes the temperature difference between warm surface water and cold deep sea water to produce electricity.

What is the primary characteristic of ocean energy?

• It is unpredictable and scarce.

• It is limited and weak.

• It is endless and powerful.

• It is costly and inefficient.

How is wave energy primarily generated?

• By the temperature difference in water.

• By the gravitational pull of the moon.

• By the surface waves of the sea.

• By the movement of ocean currents.

What causes the rise and fall of tides, which is essential for tidal energy?

• The rotation of the Earth.

• The gravitational pull of the moon and the sun.

• The temperature difference in ocean layers.

• The wind patterns over the ocean.

What does OTEC rely on to generate electricity?

• The gravitational pull of celestial bodies.

• The movement of ocean currents.

• The surface waves of the sea.

• The temperature difference between surface and deep sea water.

Which of the following is NOT a type of ocean energy mentioned?

• Ocean thermal energy

• Tidal energy

• Wave energy

• Solar energy
