Question

Assertion (A): Waves are oscillatory movements on the surface of the sea.

Reason (R): Waves result from the action of wind on the surface of the sea.

Options

• Both A and Rare true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and Rare true and R is the correct explanation of A.

Explanation:

• Assertion (A): "Waves are oscillatory movements on the surface of the sea."
  True – Waves involve the up and down movement of water particles on the sea surface, and they transfer energy without a net forward movement of water.

• Reason (R): "Waves result from the action of wind on the surface of the sea."
  True – Most waves are generated by wind blowing across the surface of the sea. The stronger and longer the wind blows, the bigger the waves become.
