Rainfall Impact on Ecosystems

Mr. Steyer's classroom video discusses how rainfall varies across different regions of the United States and its impact on ecosystems. The video uses a map to illustrate rainfall distribution, highlighting areas like the Pacific Northwest and the Southwest desert. It explains how rainfall shapes the land and affects the types of plants and animals in each region. The video also identifies patterns in precipitation, noting an increase from west to east, and discusses how changes in rainfall could alter landscapes, particularly in arid regions.
