Dating the geologic past lab
Chapter 6: Time is comprehensible to us as long as we can track it in terms of seconds, minutes, hours, days, and years, but once we go beyond the realm of our own time experience, our perception tends to get fairly vague. For example if I were to ask when Napoleon  was born, I would be lucky to get an answer like "sometime in the middle of the 18th century". We basically have trouble to visualize time intervals that are significantly larger than our own lifespan. Time is a very important variable in geology, because the exact timing of spatially separated events allows us to reconstruct the surface and surface conditions of the ancient earth.
Relative age dating of geologic features answers
What is the Geologic Time Scale. What are the major laws of relative dating? Define the Law of Original Horizontality. Define the Law of Lateral Continuity. Define the Law of Superposition. Define the Law of Inclusions. Any piece of rock included within another rock body, is older than the rock that it is present in. Define the Law of Cross Cutting. Any feature that cuts across a rock body must be younger that the rock body that it cuts across. Define the Law of Unconformities.
What are the types of unconformities? What are fossil age relations? What is Range Zone? Used in fossil age relations sequence of strata in which fossils of a particular organism are present. Explain the process of absolute dating. Uses the process of radiometric dating measure the passage of time by the rate of decay of radioactive isotopes -Represents an exponential relationship.

Historical Geology is intended for both geology majors and non-majors, and is the third term of a year of beginning college geology. This course can be used to partly fulfill graduation requirements for the Associate Degree, and has been approved for block transfer.

Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other earth sciences , including hydrology and the atmospheric sciences , and so is treated as one major aspect of integrated earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. Geology provides the primary evidence for plate tectonics , the evolutionary history of life , and the Earth's past climates. Geologists use a wide variety of methods to understand the Earth's structure and evolution, including field work , rock description , geophysical techniques , chemical analysis , physical experiments , and numerical modelling.

Our research focuses on reconstructing the temporal and spatial variability of past climate by using multi-parameter tree-ring analysis. The method uses the unique and precisely dated annual growth patterns in trees to extract information of past environmental change and relies on dendrochronology, which is the scientific method of dating old wood based on the analysis of patterns of tree rings. There are many subfields and applications within dendrochronology.

Thomas Edvard Krogh. Tom Krogh was an internationally respected scientist who developed advanced techniques in uranium-lead dating of geological processes. After over three decades, his approach and methods are acknowledged to be unsurpassed and are still used in the best laboratories around the world today. He was born and raised in Peterborough, Ontario, and received his M. He then worked at the Carnegie Institution of Washington as a post-doctoral fellow and continued on as a Staff Scientist for 11 years before joining the ROM as a Curator. His innovative technical developments permitted the acquisition of age data with exceptional levels of precision and accuracy that had previously never been achieved. Dating rocks to unravel the history of the Earth's crust by Tom, his coworkers and collaborators, has contributed to the development of an astonishingly detailed understanding of Precambrian shield areas.
