What is Uniformitarianism?
The fundamental principle of geology where physical, chemical, and biological processes that function today also functioned in the past
Who is the founder of Uniformitarianism?
James Hutton
Match the following:
Law of superposition ___ Sediment is deposited horizontally
Principle of original horizontality ___ One rock contained within another
Principle of cross cutting relationships ___ Oldest rocks are on the bottom
Inclusions ___ Younger features cut through older features
Principle of lateral continuity ___ Strata layers can be traced or mapped out from a starting point
Law of superposition-Oldest rocks are at the bottom
Principle of original horizontality-Sediment is deposited horizontally
Principle of cross cutting relationships-Younger feature cut through an older feature
Inclusions-One rock contained within another
Principle of lateral continuity-Strata layers can be traced or mapped out from a starting point
Unconformities is ____
Missing sedimentary rock
True or False:
Missing sedimentary rocks also means missing geologic time
True
What are the three types of unconformities?
Angular unconformity-Rocks are uplifted, eroded, and a layer of strata settles on top
Disconformity-A layer of strata settles on top or below an eroded layer
Nonconformity-Metamorphic or igneous rock is eroded then a layer of strata settles on top
Correlation of rock layers (stratigraphy) can be done by ____, ____, and ____
Matching rocks or similar age in different regions
Relying on found fossils
Using rock types
