There are multiple energy source in the ocean. The one thats probably the most common one are Dams. Although Dams can cause some serious flooding. Another one is Tidal energy. Tidal energy is something that turns the energy of tides into energy through Kinetic motion.<span />
Proposing a hypothesis and trying to prove and unprove other hypothesis
The particles that make up matter are the atoms.
Atoms do not change during a chemical change. They do not either during a physical change.
During a chemical change molecules change but not the atoms. The atoms separate from the original molecules and form new molecules. Then moleculas change but atoms remain being the same before and after the chemical change.
For example, atoms of oxygen in molecules of O2 combine with atoms of hydrogen in molecules of H2 and they form the molecules of water H2O.
The atoms of O in O2 are the same atoms of O in H2O and the atoms of H in H2 are the same atoms of H in H2O. The molecules changed, from H2 and O2 to H2O, but the atoms are the same.
