Fossils
100
This is when you use the layers of rocks to help determine the age of a fossil.
What is Relative Dating
100
These are the 3 main layers of the Earth.
What is the Core, Mantle and Crust?
100
This is another name for lithospheric plates.
What is tectonic plates or plate tectonics?
100
All magnets have these
What is a north and south pole?
100
Which fossil is the youngest? The fossil found in the top layer or the bottom layer?
What is Top layer?
200
These are thick moving slabs of rock that lie beneath the oceans and continents.
What is plate tectonics?
200
This is the layer of the earth that is made up of very hot molten rock. It moves slowly around the core.
What is the convecting mantle?
200
At this type of boundary, mountains are usually formed.
What is convergent boundary?
200
This is the invisible force that is related to magnets.
What is a magnetic field?
200
This is the type of rock that you will find most fossils.
What is sedimentary rock?
300
A material that has the ability to attract iron, steel, cobalt and nickel.
What is a magnet?
300
This is the layer that we know the most about.
What is the crust?
300
At this type of boundary, like in California, earthquakes happen often.
What is a transform boundary?
300
This is a tool that one can use to tell directions.
What is a compass?
300
This is the way that Scientist figure out the age of fossils when they note the layer that the fossil was found.
What is Relative Dating?
400
This is the area of the greatest pull or attraction on a magnet.
What is the pole?
400
This is the layer that consists of the inner and outer and also is made up of super hot iron and nickel.
What is the Metallic Core?
400
At this type of boundary, the result can be sea floor spreading or a rift valley.
What is a divergent boundary?
400
This is the reason that the Earth is a Giant Magnet.
What is the convection currents that are flowing around the metallic core?
400
This was the evidence that proved Alfred Wegener's theory of continental drift.
What is fossils in the same layers of Earth were found on different continents.
500
This is a hot sphere of solid iron or nickel.
What is the metallic core?
500
This is Earth's outermost shell that consists of the crust and the upper most mantle.
What is the lithosphere?
500
The reason that some areas experience earthquakes more often than others.
What is Earthquakes occur around tectonic plate boundaries?
500
This is how a compass works.
What is the needle always points to the north. This tells you which direction that you are going?
500
This is the number of carbon atoms that a fossil will have after 2 half-lifes if the organism started out with 400 grams of Carbon.
