Which of the following statements with reference to L-Wave or Long Wave generated by an earthquake is/are correct? 1. They follow the Earth's circumference 2. They travel at more or less at a constant rate Select the answer using the code given below:
C. Both 1 and 2
L-waves or Long waves are surface waves generated by an earthquake. They travel along the surface of the Earth, which means they follow the Earth's circumference. Thus, statement 1 is correct. Unlike body waves (P and S waves) whose velocities increase with depth due to the increasing density and rigidity of the Earth's interior, L-waves travel through the relatively uniform surface layers (crust). Therefore, they travel at a more or less constant rate. Thus, statement 2 is also correct. Both statements 1 and 2 are correct. Answer: Both 1 and 2
