this is an isotope that i unstable and will eventually decay to become a different atom
Radioactive isotope
the present is the key to the past
True or False: young-earth creationists believe the Bible is the truest, most accurate account of earth's history
TRUE
Of the 3 kinds of rocks, which is best for radiometric dating
igneous
this type of radioactive decay involves a proton absorbing an electron to become a neutron
electron capture
these are the two components of an atom that make up the nucleus
protons and neutrons
this type of uniformitarian thinks life arose and became what we see today solely as a result of natural processes that happened over billions of years
atheist
this is the basic view of most catastrophists
they believe that both small and large-scale catastrophes are responsible for the majority of the earth's geological features
True or False: the geological column is simply a theoretical construct. it does not literally exist anywhere in the world
TRUE
this is a vent in the earth's surface that ejects a column of hot water and steam
geyser
this determines the type of atom
number of protons
this is an example of something a uniformitarian MUST believe
natural processes like weathering and erosion happened in the past about the same as they happen today
If a young-earth creationist finds fossils below the Great Unconformity, when does he or she think the organisms that left those fossils existed?
Before the Flood
these types of rocks cannot be dated using radiometric dating because the sediments that make them up might have come from much older rocks that were weathered
sedimentary
this is an opening in the seafloor that emits hot, mineral-rich water
hydrothermal vent
this is the type of radioactive decay that involves a neutron emitting an electron to become a proton
beta decay
this type of uniformitarian thinks life was initially created by God so that it could then go through the process of evolution to become what we see today
theistic evolution
three sections that young-earth creationists typically split the geological record into
Pre-Flood, Flood, Post-Flood
this is the interpretation of the geological column that assumes life on earth started out as "simple", single-celled organisms and as time went on, organisms got more and more complex
theory of evolution
a uniformitarian conclusion of finding specific lizard fossils only in layers of rocks below mammal fossils
that type of lizard went extinct before mammals started living on Earth
this type of radioactive decay involves the nucleus ejecting two protons and two neutrons as a single particle
alpha decay
according to the uniformitarian view of the geological column, this is why we don't find dinosaur fossils and human fossils in the same layers
dinosaurs and people did not live on earth at the same time
according to the young-earth creationists' view of the geological column, this is why you don't find fossils of dinosaurs and humans in the same layers of rock
people were able to flee the floodwaters better than the dinosaurs
this is one of the processes used to date sedimentary rock where you can determine the ages of the layer of igneous rock above and below the sedimentary rock
bracketing
You are watching a sample of radioactive isotopes. You initially have 600 of these atoms. After 6 hours, you have 150. What is the half-life?
3 hours
