T God . loves us, and made the world . with us in mind. . S The sun . emits radiation which travels to the earth as light and heat.. T God . wants us . to love and obey Him. . S We . are mammals, like many others species on earth, and quite similar genetically to some of them.. Geological Time Scale. AIM: . How have stratigraphy and radiometric dating been used to construct the geological time scale?. The History of Earth. Earth’s history has been studied through 2 methods:. Lecture 3. Development of. Geological Concepts, Part I. Major Concepts. In the 17. th. and 18. th. centuries (Age of Reason), application of the scientific method of observation and interpretation began with the purpose of understanding earth processes in the context of the biblical account, but wound up challenging and discrediting that explanation. . How does the atmosphere support life?. The atmosphere allows us to breathe. Many different types of organisms need oxygen to perform life processes. Plants require carbon dioxide to undergo photosynthesis. . CHAPTER 25. CAMPBELL and REECE. Conditions on early Earth made the Origin of Life possible. Macroevolution :. evolutionary change above the species level. examples:. emergence of terrestrial vertebrates. Conditions on early Earth made the Origin of Life possible.. Current theory about how life on Earth began.. Earth formed about 4.6 billion years ago.. Earth was too hot and still being bombarded by meteors, any water evaporated.. Geologic Time and Evolution Earth Has a History Geologic materials record enormous changes. Earth is a complex, evolving system. Physical and biological systems continuously interact. Earth constantly changes and has done so through time. Eras of Earth’s History EQ: What causes changes in the Earth? How does knowing the past give us a VISION for the future?
