If your child says something hateful, then itâs helpful if parents can get to the root of their anger, Kimberly G. says, noting parents have to listen to their children. My girls tell me when I do something they donât like, and sometimes theyâre right about it.
Other examples of transverse waves include light waves and water waves. Both types of seismic wave can be detected near the earthquake centre but only P-waves can be detected on the other side of the Earth. This is because P-waves can travel through solids and liquids whereas S-waves can only travel through solids. This means the liquid part of the core blocks the passage of S-waves.
Surface Waves - Radiate from the epicenter and travel along the Earth's surface. Have up and down rolling motion, and side to side vibrational motion. During an earthquake, the Earth's surface 'rolls' like waves on the open ocean and moves from side to side. Body Waves - Radiate from the focus and travel throughout the earth's interior. There are two types of body waves: P-waves and S-waves. P-wave (primary wave) - A compressional wave that causes alternate compression-expansion of the rock. Move through both solids and liquids (Fig 8.8 A).
