Name two forms in which solar energy manifests itself in oceans.

(N/A) Solar energy manifests itself in oceans primarily in the following two forms:
$1$. Ocean Thermal Energy: This is caused by the temperature difference between the warm surface water and the colder deep water of the ocean.
$2$. Tidal Energy: This is caused by the gravitational pull of the Moon and the Sun on the Earth's oceans,which creates the rise and fall of sea levels.
