Question | Answer |
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 |
