Many birds are VERY soft to the touch .
Geological forces gift us with the mountains and valleys, oceans, fjords, lakes, cliffs, and caves. They are directly responsible for topography, which influences local weather patterns. Geology determines directly and indirectly the biological component of Earth. Finally, geological forces provide us with an economic base in the form of ores, fuels, minerals, and, of course, jewelry. In the birds, the wind, the rustling leaves, moaning tree branches, trickling creeks, lapping waves, in musicians, and in you.
