Question

Assertion (A): A tsunami is a large destructive ocean wave that can be generated by any disturbance that rapidly displaces a large mass of water.

Reason (R): The most common cause is an undersea earthquake.

विकल्प

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

Explanation:

A tsunami is indeed a large, destructive ocean wave caused by any sudden disturbance that displaces a huge volume of water, such as landslides, volcanic eruptions, or undersea earthquakes. However, the most common cause of tsunamis is an undersea earthquake, which suddenly shifts the sea floor and displaces water above it. Therefore, both the assertion and the reason are true, and the reason correctly explains why tsunamis form.
