Rocks
What are the 3 types of Rocks?
Igneous, Sedimentary, and Metamorphic
The literal study of Earth
Geology
Relics of organisms that lived and died
Fossils
Waves that compress like a spring
P-waves (primary, compression waves)
Driving force of Earth's crust that produces constant change.
Plate Tectonics
How do we determine the RELATIVE age of a sample?
Studying the Strata or Rock Stratification
The part of Earth that contains the upper mantle and the crust.
Lithosphere
What type of rock are fossils primarily found in?
Sedimentary
Waves that can't penetrate liquid
S-waves (Secondary, Shear waves)
Products of plate tectonics and mantle convection that releases CO2 and other gasses into the atmosphere.
Volcanoes
Which type of analysis is used when comparing parent and daughter isotopes in a sample?
Isotopic analysis/Radiometric dating
What are the (4) layers of Earth in order from inner most to outermost?
Inner core, Outer core, Mantle, Crust
Part of the geological record that is formed by fossils, and is easily destroyed.
The Fossil Record
Which layer of Earth was discovered to be liquid because of the behavior of seismic waves traveling through the earth?
Outer Core
Theory of how Earth's Moon was formed.
Giant Impact Theory
