geology byui science
Earth’s geologic record could be accounted for by aseries of brief, large-scale catastrophic events.
the laws governing nature have remained uni-form through time.
the sediments that make sedimentary rocks are originally deposited Original horizontalityin horizontal layers
Principle of superposition
older sedimentary rock units in an undisturbed sequence are found below younger units
Principle of lateral continuity
sdeimentary rock layers that have been seperated by erosion were once continuous
a rock unit that is broken formed before the break in it did
the material wholly included inside a rock existed befefire the rock that surrounds it did.
fossil remains could be used to identify layers of sedimentary deposits even if those layers are discontinuously spread over large areas.
How do the principles of original
horizontality, superposition, lateral continuity, cross-cutting
relationships, inclusions, and fossil succession apply to relative dating?
Why was catastrophism accepted by some people in the scientific community?
Why is uniformitarianism a more
effective explanation for geological processes that take place on earth
What barriers inhibited the development of key ideas in geology?Are any of these barriers present today?
Explain the difference between the two hypotheses of catastrophismand uniformitarianism.
Who were the important people in the development of the principlesof relative dating and uniformitarianism?
What is meant by “relative dating”?
developed the principle of uniformitarianism and presented his publication of the theory to the Royal Society of Edinburgh in 1785.
wrote and published the foundational, three-volume, modern-day textbook in geology in the early 1830’s.
What are macroscopic dating methods?
Explain how the following macroscopic dating methods work: Tree rings,
Glaciers, Glacial lake sediments.
What is radiometric dating?
How can radiometric dating be used to measure the age of different
Explain how carbon-14 dating can be used to measure the age of organic
Explain how the uranium-lead dating system works.
