What are body waves.

1.	What are body waves.
Answer» A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth\'s surface.\xa0Body waves\xa0are of two\xa0types: compressional or primary (P)\xa0waves\xa0and shear or secondary (S)\xa0waves. P- and S-\xa0waves\xa0are called "body waves" because they can travel through the interior of a\xa0body\xa0such as the Earth\'s inner layers, from the focus of an earthquake to distant points on the surface.
