[|video] //**• The Western Hemisphere has a long geologic history (plate tectonics)**// //**3.1c, 3.1d • Geological processes shaped the physical environments of the Western Hemisphere (Ice Age, weather, wind, and water) 3.1d, 3.2b **//  Read: Goodman, Susan E. //On This Spot: an Expedition Back through Time//. This picture book introduces the concept of change through time from present-day Manhattan through the nearly barren rocks of 540 million years ago. **(**This is my own book. See me.)
 * 1. Introduction/Connect Phase:**

(a) "Our Restless Planet: Plate Techtonics and Pangea." **Click [|here]** for this video link to the site, //How Stuff Works.//
 * 2. Plate tectonics:**

(b) "Mountain Maker, Earth Shaker." **Click [|here]** for virtual interaction with plate movement from PBS. Follow the links under "For more information, check out these," to find simple explanatory text.

(c) "What on Earth is Plate Techtonics?" A site from USGS for the composition of the Earth and explanation of plate techtonics. **Click [|here]. Also [|click]** to see the position of the continents throughout time.

(d) **Click on [|Rocky Mountains]** to watch a video from //How Stuff Works// about how they were formed.

(a) Here are two related video segments on **erosion** and the formation of **canyons.** [|Part one]: "Canyons: How Erosion Works." [|Part two] : "Canyons: Forces of Erosion." (b) **Glaciers** (1) This [|video] explains the formation of glaciers and the effect they have on land masses: "Land and Water: Glaciers." (2) This second [|video], "The Really Big Floods: The Cordilleran Ice Sheet," explains the formation of a glacial lake in Montana during the last Ice Age. (3) For evidence of changing sea levels (related to ice ages), view [|this].
