Glaciers
"The best I have seen on this topic."
Dr. John S. Moyle Bronxville, NY High School
Award-winning photography shows glacial erosion and deposition in action! Advancing ice
masses carve U-shaped valleys and leave a trail of lakes and erratics, while melting
glaciers deposit kames, drumlins and outwash plains. Covers Alpine and Continental
glaciation. Animation sequences help explain key processes. 15 minutes |
