This webpage provides a single page summary of erosion that could be used for teachers and students to gain background information. It includes a time lasped video of coastal erosion in Alaska. The reading level of the page is above an average second grade reading level. It may need to be read by the teacher along with discussion of terms used. Since there is no audio with the video, there would be need to be an explanation about time lapse of the erosion taking place and how long it took for the land to erode from start to finish in the video.
