Principles/Laws
This principle sees evidence that rapid, highly energetic events operated over short periods of time and did much geological work rapidly
What is the principle of catastrophe
What are fossils?
What is the remains of plants and animals that were once alive
This occurs when tiny bubbles in moving water explode inwardly
What is Cavitation
The process of using the rate of atomic decay to determine how old an object may be
What is Radioisotope dating
The eruption of molten rock (magma) onto the surface of the earth
What is Volcanism
Past processes are no different than processes today, everything happens by gradual processes over very long periods of time
What is the principle of uniformity
Name 4 types of fossils
What are frozen animals, animal tracks and worm burrows, coprolites, gastroliths
This is where rocks are picked up by moving water
What is Plucking
A process that uses the decay of carbon 14 to estimate the age of things that were once living
What is Carbon dating
An opening in the earth’s crust, usually associated with volcanic activity
Fumaroles
Everything in the universe is subject to
What is the law of disintegration
Fossilized dung found in rocks is an example of what kind of fossil?
What is Coprolites
This is like an underwater tornado that breaks up rock
What is Kolk
The basic component of chemical elements
What is an atom
An underwater, rapid deposition of mud that hardens into a layer or rock
What is Turbidite
Something happening at the same time
Synchronism
Siberia and Alaska have millions of preserved mammoth bones, this is an example of what kind of fossil?
What is frozen animals
Natural materials broken down by processes of erosion and weathering, can be transported or deposited by water or wind
What is Sediment
Variations of an elements atoms, usually in the different number of neutrons
What is an Isotope
The process by which trees, plants, and even animals are solidified by burial in hot, silica rich water
What is Petrification
Also referred to as the second law of thermodynamics-disorder of the universe increases over time
What is the Second law of Science
When a dinosaur fossil is found with many smoothly polished stones inside it's body is called?
What are Gastroliths
This type of erosion takes place when chemicals in the air and water react with minerals in rocks, dissolving them.
What is chemical erosion
What are three possible problems of dating?
1. Have the decay rates always been the same?
2. What if some of the parent or daughter elements were gained or lost?
3. What if some of the daughter elements were present at the start?
A box in which human bones were preserved
What is an Ossuary
