Document Summary
How the earth was made how it is: Those things were signs of decay or wrath. Layered in strata, younger on top of older. All layers are formed by sediments that are compressed together. The fossils are the remains of those who had lived near the waters. With commercialism it was profitable to figure all this out to get resources. Realized that there were plants and animals that can be associated with certain types of rock. Only fine sediment makes good impressions for fossils. Depends on how fast the water was moving when they got deposited. Can drop huge parts of continental rock (drop stones, good signs of glaciers after the fact) Ice ages when huge temperate zones are covered too. When they burned, they melted the other rocks, meaning volcanoes and tertiary igneous rocks. Opposed by volcanists: they didn"t think there were different creation periods. The forces seen today are the ones that had always been working together.
