In the past week you have learned two major geologic theories. Widely held beliefs, ______1_______, the changes to the Earth happen suddenly and _________2___________, the gradual changes over time. The author of The Theory of the Earth; _______3_______, and ________4_________; Principles of Geology, were the founding fathers of uniformitarianism. The slow changes to the earth are a result of ________5_________, the physical, chemical, and biological changes to the Earth. Weathering can result in a sequence of rock layers called ______6_______. The formation and breakdown of rock is dependent on rock structure. Rock formation is dependent on ______7________ composition, composed of only one substance. Three types of rock are _________8__________(sediment), _______9________(magma), and _______10_______ (existing rock). The breakdown of rock is effected by stress and weathering. Stresses included __________11_______, when rocks are pushed together. __________12__________, when rocks are pulled away from each other, _______13________ stress, pushed and pulled in opposite directions.
14. Label the following diagram, making sure to list the forces acting on each type of rock.
In the past week you have learned two major theories associated to geology. A widely held belief, ______1_______, the changes to the Earth happen suddenly and _________2___________, the gradual changes over time. The author of The Theory of the Earth; _______3_______, and ________4_________; Principles of Geology, were the founding fathers of uniformitarianism. The slow changes to the earth are a result of ________5_________, the physical, chemical, and biological changes to the Earth. Weathering can result in a sequence of rock layers called ______6_______. As the younger layers are set upon the older layers you would see the _________7____________. The geologic column shows ________8__________ the history of the Earth through fossils of past life. Geologists would be able to determine the _________9___________of particular events by looking at fossils and the geologic column. Under the best circumstances geology would follow the pattern of superposition. However, as you have learned large geologic events can create ______10_______in the geologic column. This unconformity would disrupt the sequence of the geologic column.
