52. Which of the following statements are correct with reference to earthquakes?
A. All natural earthquakes take place in lithosphere which refers to earth crust and depth up to 1000 km from the surface of the earth.
B. Secondary seismic waves (S waves) help in studying the interior of the earth because of its property to travel only through solid materials.
C. Surface waves are more destructive than body waves.
D. Earthquake’s magnitude scale is known as Richter scale and earthquake intensity is known as Mercalli scale.
Choose the correct answer from the options given below:
- Only one statement is correct
- Only two statements are correct
- Only three statements are correct
- All the statements are correct
Answer: (3) Only three statements are correct
Explanation:
- A. False. The lithosphere typically extends to about 100 km in depth. Most natural earthquakes occur within the lithosphere, but they do not typically extend to depths of 1000 km.
- B. True. Secondary (S) waves can only travel through solid materials, and this property helps in understanding the interior structure of the Earth.
- C. True. Surface waves are indeed more destructive than body waves because they travel along the Earth's surface and cause the most intense ground shaking.
- D. True. The Richter scale measures the magnitude of earthquakes, while the Mercalli scale measures the intensity based on observed effects.
Statements B, C, and D are correct.
