POG Flashcards
the study of the earth, it’s composition, structure and history and the processes that shaped the earth of the past and those that would continue to mold the earth of the present
Geology
supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation
Hypothesis
hypothesis expressed as a visual or statistical simulation or as a description by analogy of a phenomena or process that are difficult to observe and describe directly
Model
widely accepted explanation for a group of known facts
Theory
Steno’s law
Law of original horizontality
Law of Superposition
Law of Lateral Continuity
states that Bed were deposited nearly horizontal due to gravity
Law of original horizontality
States that the younger layer lies at top and the older lies on the bottom.
Law of Superposition
Strata is deposited laterally until the sediment supply last or encounter any geologic barrier
Law of Lateral Continuity
Ordering strata by examining the fossils contained in them
Law of Faunal Succession
states that fossil organisms succeed one another in a definite and determinable order, therefore any time period can be recognized by the fossil content
Principle of fossil succession
remains of a prehistoric life
Fossil
events are placed in the proper sequence or order without knowing their age in years.
Relative Dating
assumption that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe: “The present is the key to the past.”
Uniformitarianism
states that the physical, chemical and biological laws that applies today also operated in the geologic past
Uniformitarianism
he proposed the uniformitarianism
