Task F: The professor will take you to location F, where you would examine the rock and note the straight, parallel grooves and ridges on the surface of the rock, and parallel grooves cut across the layering of the rock. Create an hypothesis as to why the grooves formed on the rocks, make observations, draw conclusions, and devise a test of its correctness in the form of a prediction. Rock F is bedrock that points north-west, matching up with the empire rock. It also has grooves, is polished, and is glacial erratic. . The hypothesis that was created as to what process formed the parallel groves was, The Glacier Theory. What occurred in this process was that, 15 thousand years ago, the whole section was covered with flowing ice that had huge boulders underneath it. When the ice dragged the boulders over the bedrock that was pressing against it, the smaller particles of the ice that were dragged created the grooves, which are called striations. This process is still acting on rocks because things like the Anartic sheets still exist, and these were created in the “Ice Age”, which was the period of time where there was an expansion in the ice sheets. By observing the rock you can picture the ice sheets, with huge boulders scratching. The results of creating a hypothesis as to why parallel grooves were created on the umpire rock pertain to the geology of New York City at large because, it involves the process of the Ice Age. The Ice Age was a very significant period of time throughout the world in which created a huge change to the environment. The Ice age brought temperatures so cold that ice sheets were created in different areas. Parallel grooves (TaskF)
