QUEENS UNIVERSITY GEOL 104 LATEST 2025 FINAL EXAM WITH QUESTIONS AND CORRECT
VERIFIED ANSWERS 100% PASS
Carbon Dating - (ANSWER)Uses properties of radiocarbon to determine the age of an object.
Fossil Succession - (ANSWER)A technique used to define the RELATIVE AGE of a fossil.
Relative Age - (ANSWER)The age of one feature with respect to another.
Numeric Age - (ANSWER)The absolute age of a feature in years.
Paleomagnetism - (ANSWER)The study of ancient magnetism preserved in rocks.
Unconformities - (ANSWER)Angular Unconformity: Rocks below were tilted or folded before the
unconformity developed.
Nonconformity: Sediment rocks overlie older intrusive igneous and/or metamorphic rocks.
Disconformity: Old sedimentary layers erode away overtime, this lasts over a long period of time before
new layers of deposition accumulate. This leaves a gap in between time periods.
Stratigraphy - (ANSWER)The discipline that studies the layering of rock layers.
A stratigraphic unit is used to describe parts of formations.
Geologic Contact - (ANSWER)the boundary surface between two formations. Comparable to other
contacts such as faults, unconformities, and intrusive contacts.
Conformable Contact - (ANSWER)No time gap between boundary surfaces

VERIFIED ANSWERS 100% PASS
Unconformable Contact - (ANSWER)There is a Time gap between boundary surfaces.
Isotopic Dating - (ANSWER)dating methods based on scientific knowledge about the rate at which
various radioactive isotopes of naturally occurring elements transform themselves into other elements
by losing subatomic particles.
This rate is CONSTANT.
Stable isotopes do not undergo change overtime, while unstable isotopes undergo radioactive decay by
releasing energy but creating a different element.
283U to 206Pb has a half life of 4.5 billion years, roughly the age of Earth!
Orogen - (ANSWER)a belt of the earth's crust involved in the formation of mountains. This mountain
building leads to deformation in rocks.
Rock Derformation - (ANSWER)Displacement: Change in location
Rotation: Change in direction
Distortion: Change in shape
- Stretching
- Shortening
- Shear strain
Deformation Rate - (ANSWER)Rapid = Brittle: Atomic bonds break forever and lead to fracturing.
