Document Summary
Geology- is the science that pursues an understanding of planet earth. Physical geology- examines earth materials and seeks to understand the many processes that operate on our planet. Historical geology- seeks an understanding the origin of the earth and its development through time. Many important relationships exist between people and the natural environment. Uniformitarianism- the physical, chemical, and biologic laws that operate today have operated throughout the geologic past. The rocks at the bottom of the grand canyon are 1. 7-2. 0 billion years old. The most recent layer of sediment is about 250 million years old. The explosive impact of a meteorite created a 1. 2km wide crater in just a few seconds. Science assumes the natural world is consistent and predictable. The goal of science is to discover patterns in nature and use the knowledge to make predictions (rules). How or why things happen are explained using:
