Question

1. which body wave arrived first at any point distant from the epicenter of the earthquake?

a. p waves
c. l waves
b. s waves

Explanation:

P - waves (primary waves) are the fastest seismic body waves. They are longitudinal waves that can travel through solids, liquids, and gases. S - waves (secondary waves) are slower than P - waves and can only travel through solids. L - waves (surface waves) are the slowest and travel along the Earth's surface. So, at a point distant from the epicenter, P - waves arrive first.

Answer:

a. P waves
