Notes

when glaciers move over the surface they leave behind evidence in the form of the glacial striations or deep scartches in the rock thta shows the direction the ice moved as it dragged over the surface. interestingly if you look on where on the earth we find the glacial striations today ther are located in areas like the amazon rainforest on the equatorial south american continent and the hot sticky jungles of central africa. these are places you could not find glaciers today simply because they're too close to the equator and getting sunlight that is too intense and hot preventing glaciers from forming, and so what wegener concluded was that these areas are not always near the equator but rather in the past they were located closer to the poles where a colder climate could exist and support glaciers
glacial striations-are a series of long, straight, parallel lines or grooves scratches onto a bedrock surface by rock fragments lodged in the base of the moving glaciers
glaciers- is a persistent body of dense ice that is constantly moving under its own weight
