This scientist came up with the current model of Solar System formation.
Simon Laplace
100
This scientist came up with the Theory of Plate Tectonics.
Who is Alfred Wegener?
100
This priniciple assumes that the processes that shaped the early earth and universe are still at work today.
What is uniformitarianism?
100
This dating method correlates layers of sedimentary rocks to determine their age.
What is Lithostratigraphy?
200
This is the crust and uppermost layer of the earth.
What is the lithosphere?
200
This type of rock provides the best evidence of what the early solar system was like, about 4.6 billion years ago.
What is a carbonaceous chondrite.
200
This phenomena, of rows of magnetic iron pointing toward different poles of the earth, near the center of the ocean, provided conclusive evidence of Wegener's Theory.
What is seafloor spreading?
200
Pangaea existed during this geologic period.
What is the Cretaceous?
200
This method looks at the leftover atoms of radioactive decay, to determine the age of rocks.
What is Radiometric dating?
300
This is the 2nd highest layer of the earth. It is molten, and the tectonic plates float around on it.
What is the Asthenosphere?
300
A small planetary body accreted from the original solar nebula.
What is a plantesimal.
300
This type of plate boundary pushes up mountains, as one plate moves beneath another.
What is a convergent boundary?
300
This era is the time from 65 million years ago to the present.
What is the Cenozoic?
300
The first known scientist to study strata for the purpose of aging.
What is Georges Cuvier?
400
A body of water in highly permeable rock or regolith, lying in the zone of saturation.
What is an aquifer?
400
The original cloud of rotating gas and dust that acted as a solar system seed.
What is the Solar Nebula?
400
The most abundant minerals in metamorphic rocks are rich in these?
What are silicates?
400
Geologic time periods consisting of 100's of millions of years.
What are Era's?
400
A method of relative dating that utilizes the presence of fossil organisms.
What is biostratigraphy?
500
This term describes the Earth's plates "floating on the asthenosphere like blocks of wood on water."
What is isostacy?
500
Scientists have determined the age of the early solar system by measuring these.
What are isotopes?
500
These are six common silicate minerals found in igneous rocks.
What is quartz, feldspar, mica, pyroxene, amphibole, and olivine?
500
The process of determining the age of one stratum relative to another.
What is relative dating?
500
The determination of age in years before present is called this.
