Q. Consider the following statements:
1.Divergent plate boundaries are commonly associated with the generation of tsunamis.
2.Most natural earthquakes naturally occur in asthenosphere.
Which of the statement(s) given above is/are correct?
Answer: D
Notes:
Explanations –
Statements 1 and 2 are incorrect. While tsunamis can occur at divergent plate boundaries, they are most commonly associated with convergent boundaries, especially in subduction zones where one tectonic plate is forced beneath another. Most natural earthquakes occur in the lithosphere, which includes the Earth’s crust and the uppermost part of the mantle. The lithosphere is rigid and brittle, making it prone to breaking and releasing seismic energy. The asthenosphere, located beneath the lithosphere, is more ductile and less prone to generating earthquakes.
