Question

Ocean thermal energy is due to:

• A. Temperature difference at different levels in the ocean.
• B. Energy stored by waves in the ocean.
• C. Pressure difference at different levels in the ocean.
• D. Tides arising out in the ocean.

Answer 1

The correct option is A Temperature difference at different levels in the ocean.

Ocean thermal energy is generated due to the difference in temperature of water at the surface of the ocean and temperature at deeper levels of the ocean. This energy comes indirectly from the sun as the heat energy from the sun is creating the difference in temperature.
