walking with a geologist

Walking with a geologist was a very impactful experience. I learned how land is molded, how water and land erosion can impact communities, and the importance of geology to life. bob took us back in history to show us how dayton got the way it did.  One of the most recent contributors to todays landscape was caused by glacierss scraping and chipping away at the earth as they moved south.  Much of ohios rivers and lakes were formed during this time.  The glaciers also provided a great gravel industry here.  As the glaciers were mowing the earth they caravaned limestone and lagre boulders and dropped them of to be used by ohioans for gravel and concrete. Bob also taught us how water and erosion can cut into our communities.  As the water in rivers bend around and hug curves, the faster water chips away at the banks and rocks.  This action leads to a river that changes direction, and this could be a threat to bridges, roads, and buildings in our community.  With out geology there would be many natural disasters including floods, droughts, sewage problems, fallen bridges, and flodded buildings and homes.
