Cubangbang's 8th Ch. 13 Geology Stack #123392

The study of the earth Geology
3 layers of the earth Crust, mantle, core
Thinnest layer of the earth Crust
Scientists believe the earth's core is composed mostly of Iron
Deepest hole drilled in the earth reaches to a depth of 12 Kilometers
Readers of the Bible concluded from these verses that Adam & Eve were created as young or middle aged adults. Genesis 2:15 & Genesis 1:28
Evolutionists believe the earth's age is 4-5 billion years
Young-earth Creationists believe the earth's age is about 6,500 years
Dating methods Radioactive dating, Radiocarbon dating, uranium-lead method, and potassium-argon method
Radiocarbon dating is fairly accurate for carbon-containing specimens younger than 5,000 years old
Geologists that study earthquakes waves Seismologists
What did God do on the 7th day of Creation Rested
Layers of rock within the earth's crust Strata
Key principle of uniformitarianism The present is the key to the past
Dating method used when counting tree rings to determine age Dendrochronology
The old-earth view of the earth's history, which assigns to rocks ages that extend far back into time Deep-time viewpoint
Theories and models of the earth's formation and the processes that shaped its surface Historical geology
Material that has settled out of a body of water Sediment
An argument against the doctrine of uniformity Fossil graveyards
Peformed genealogical dating Ussher
The change of a radioactive element into a different radioactive or nonradioactive element Decay
Marks a boundary between two layers of the earth when there is a change in speed Discontinuity
Boundary between the crust and mantle. A seismic discontinuity in the earth that marks the depth where earthquake waves suddenly chsange speed as they travel through the earth. Mohorovicic discontinuity (or Moho)
The pressure of this part of the earth are extremely high. It is believed to have a liquid outer part. It contains 16% of the earth's volume. Core
Two different zones of rock act together as a unit to form the plates of the earth's shell. Lithosphere
Earthquake waves do not increase with depth as fast in this zone as they do in the rest of the mantle, perhaps because rocks are closer to melting. Asthenosphere
Occupies 84% of the earth's volume.At some levels of this region, rock is thought to flow in slow convective patterns. Earthquakes travel faster here than in the crust. Mantle
Know how to label the Earth's interior (Drawing on p.341)
This dating method uses tests such as liquid scintillation counting and an instrument called an accelerated mass spectrometer. Uses the ratio of carbon-14 and carbon-12 to determine age. The most reliable form of radioactive dating. Radiocarbon dating
This dating method examines a process that occurs at a constant rate. Radioactive dating
This method is based on the radioactive decay of uranium into lead by a chain of other radioactive elements Uranium-lead method
This method uses the ratio of argon to find the age of the rock Potassium-argon method
A scientist who studies mainly the solid structure of the earth. They can also study satellite photos of the earth in search of oil deposits. Geologist
A geologist who studies earthquakes Seismologist
