Bonus: Scientists
Someone who studies Geology
Geologist
These are most likely to be found in sedimentary rocks.
Fossils
An event that kills mass quantities of plant and animal life.
Mass extinction
Name of liquid rocks below the surface AND Name of liquid rocks above the surface.
Name BOTH to get points.
Magma is below ground, Lava is above ground
Process where a solid rock turns into liquid magma
Melting
Someone who studies animals (hint: like at the zoo)
Zoologist
Describe what absolute aging is.
Determines the exact age of a rock (using radiometric dating and ion half life).
Type of igneous rock that forms inside of the earth, cooling really slowly
Intrusive
Type of rock that forms distinct layers over long periods of time.
Sedimentary Rock
Heat & Pressure
Someone who studies living things
Biologist
Describe what relative aging is
Determines a rocks age in comparison to something else, like an index fossil
The rate in which a rock cools determines the presence/size of these.
Crystals
Type of rock that forms due to high heat and high presure
Metamorphic Rocks
Process where magma or lava turns into an igneous rock.
Cooling
Someone who studies the climate
Climatologist
What does the Law of Superposition tell us?
The youngest rock layers are at the top and the oldest rock layers are at the bottom
Type of igneous rock that forms on the surface/outside of the earth, cooling really quickly
Extrusive
Type of rock that forms after being ejected from a volcano
Igneous Rocks
Process where sediment is squished together due to time/pressure
Compaction
Someone who studies weather
Meteorologist
How old is the earth?
4.6 Billion Years Old
(Give points for anywhere between 4-5 billion years)
Name all three units of geologic time from longest to shortest (big to little)
Eon, Era, Period
Type of rocks that form due to weathering.
Sediment
Process where larger rocks of any type are broken into smaller and smaller pieces
Weathering
