the Dayton area different back then relative to today?
Additional Hints:
• Throughout this course, I have frequently reminded you that there are three important minerals to
remember: Feldspar (particularly Orthoclase Feldspar), Quartz, and Calcite. What are the
chances that these minerals are the answers to Questions 4, 5, and 6?
Throughout this course, I have frequently reminded you that there are six broad categories of
igneous rock and that there are two important ones to remember: Granite and Basalt. What are
the chances that one of these is the answer to another question?
• Throughout this course, I have frequently reminded you that there are four broad categories of
sedimentary rocks to remember: Conglomerate, Sandstone, Shale, and Limestone. The first three
are differentiated by the size of their grains (Conglomerate has the largest grains and Shale has
the smallest), and Limestone is made of the calcite skeletons of tiny sea creatures. Conglomerate
tends to form in mountainous headwaters, Shale and Limestone tend to form in oceans or large
lakes, and sandstone tends to form between those locations. What are the chances that some of
these four rocks are the answers to a few more questions?
