1. Tsunamis have very short wave length and high amplitude in the deep sea. |
2. As the tsunamis reach the coast, their wave length increases and amplitude decreases. |
A) ?1 only ????????????????????????
B) ?2 only
C) ?Both 1 and 2???? ???????????
D) ?Neither 1 nor 2
Correct Answer: D
Solution :
?In the deep sea, tsunamis have very long wave length which often exceeds 500-700km. But their amplitude is very low and rarely exceeds 1 meter. However, on reaching coast, wave length of tsunamis is reduced considerably and their amplitude increase to 10-30 meters.You need to login to perform this action.
