Which of the following statements about rockslides is correct?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Sudden movement of a large mass of rock along a defined slope plane.
A rockslide refers to the rapid and sudden downward movement of detached rock masses along a clearly defined slope or bedding plane. It occurs when the stability of a rock slope is lost due to factors such as weathering, earthquakes, heavy rainfall, or human activities like blasting. Unlike slow movements, a rockslide is quick and dangerous, often causing significant damage.
