Question

How are waves formed?

• A. They are formed due to the alternating winds blowing over the ocean surface.
• B. They are formed due to the gravitational force exerted by the Sun and the Moon on the Earth.
• C. They are formed due to the disturbances in the Earth's crust.
• D. They are formed as they are a natural movement of the ocean.

Answer 1

The correct option is A They are formed due to the alternating winds blowing over the ocean surface.

Alternate rise and fall of water on the ocean surface is called waves. This alternate rise and fall happen due to winds blowing over the surface of oceans. As the winds hit the water surface, the force causes the water to rise and fall. Stronger the winds, more the force and bigger the waves.
