Final answer:
The cause of large ocean waves being pushed onto the shore due to a rise in sea level is primarily storm's winds. Tides, underwater earthquakes, and volcanic eruptions can also contribute to wave formation, but they are not the main cause of large waves being pushed onto the shore.
Step-by-step explanation:
The cause of large ocean waves being pushed onto the shore due to a rise in sea level is primarily storm's winds. When strong winds blow across the surface of the water, they transfer energy to the water, causing waves to form. The stronger the wind, the more energy is transferred, resulting in higher waves. Tides, underwater earthquakes, and volcanic eruptions can also contribute to wave formation, but they are not the main cause of large waves being pushed onto the shore.
