PPT-Ch.8 How Waves Move Sediments

Longshore Drift Longshore drift has a very powerful influence on the shape and composition of the coastline It changes the slopes of beaches and creates long narrow shoals of land called spits that extend out from shore . http://www.youtube.com/watch?v=JN3BQxSroGs.

We all know what ocean waves look like. Even if you’ve never been to the seashore, you’ve most likely seen waves on TV. . water. and . energy. . Anyone who has watched breakers roll into the shore, or been seasick on a boat, knows very well that waves move. But surprisingly, the water in waves doesn’t travel much at all. Waves transfer energy!. A wave does not carry matter . It only moves matter as it travels through it.. Waves. Compression (longitudinal) waves . are waves in which the particles of the medium move in a direction . Finley’s 6. th. grade Science. Table of contents. How science works pg 1-2.

Explain the relationship among waves, energy, and matter. 2. Describe the difference between transverse waves and compressional waves. A. Waves Carry Energy. Waves (rhythmic disturbances that carry energy without carrying matter) can carry energy by itself or with matter. A wave is any disturbance that transmits energy through matter or empty space.. Energy can be carried away from it’s source by a wave. As a wave travels, it does work on everything in it’s path. - Jon . Kabat. -Zinn. Waves are moving . energy. !. Most waves wind-driven.
