Question

What is the difference between waves and tides?

Answer 1

Hint: Waves are the disturbance of the water on the ocean or sea in the form of moving swell or ridge. The regular change in the level of ocean due to the moon and sun is called Tide. High tide is sea closer to land and low tide is sea further from land and more land area visible.

Complete step-by-step solution:
Tides: Due to the interaction of the gravitational pulls between the moon, sun to the Earth leads to the formation of Tides. There are two types of tides i.e. High tide and low tide. High tides mean the level of the ocean is closer to the land. When the tide is high the level of water in the ocean becomes high and the water covers more land than usual and hence closer to land. When the tide is low the level of water in the ocean is low and more land is visible. Here the power generation is intermittent.
Waves: Waves are the disturbance in the water in the ocean due to the high-pressure winds or due to the high pressure of water occurring by big ships in the ocean. The force exerted by wind and water forms waves. Here the process of power generation continues due to the reservoir of water.

Note: High and low tide occurs twice a day and waves are dynamic in nature. Tidal energy conversion uses the kinetic energy of water directly since it cannot be controlled. In hydro energy the flow of water can be controlled using dams to build its potential energy.
