ANIMATION: Beach Drift
This animation illustrates the sawtooth motion that causes sand to gradually migrate along beaches in a process called beach drift, and shows how this can create sand spits in places where the coastline indents landward. For more information, see Section 18.6 Where Land Meets Sea: Coastal Landforms starting on p. 638 and Figure 18.20 in your textbook.
Zoomable Art: Oceans and Coasts
The oceans of the world provide a diverse array of environments illustrating the full complexity of the Earth System. Tectonic processes and surface processes constantly battle with each other to produce submarine and subaerial landscapes. For more information, see the Featured Painting on pp. 652-653 in your textbook.
