Consider the following and mark the correct statements:

1. The anti-centre is the antipode of an epicentre of an earthquake.

2. Shadow Zone refers to the zone in earth"s surface in which we do not register P or S waves or both.

3. Body waves are the most damaging waves for they create density differences leading to stretching and squeezing of material.

4. The shadow zone of S-wave is much larger than that of P-wave.

Select the correct answer using the code given below.

1, and 4 only

1, 2, and 3 only

2, 3, and 4 only

1, 2, and 4 only

.EXPLANATION:

?STATEMENT 3 IS INCORRECT. Body waves are not the most damaging waves for they create density differences leading to stretching and squeezing of material. Surface waves - most damaging. (directly and intensely affect the infrastructure built over land)
Shadow Zone refers to the zone in earth's surface in which we do not register either P-waves or S-waves OR BOTH. The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake.
The shadow zone results from S waves being stopped entirely by the liquid core and P waves being bent (refracted) by the liquid core.
Body waves are not the most damaging waves for they create density differences leading to stretching and squeezing of material. Surface waves - most damaging. (directly and intensely affect the infrastructure built over land).
