Is you wanted to calculate the density of an object you would use this equation.
What is d=m/v
100
Thin, dense plate
What is Oceanic Plate
100
Earth's most recent supercontinent
What is Pangea
100
The SOLID material ejected from a volcano
What is tephra
bonus* 100 pts Name the main 3 in size order
200
Earthquakes are known to take place here.
What is convergent, divergent and transform boundaries.
200
Density can be described as
What is the compactness of matter.
200
Thick, less dense plate
What is Continental plate
200
Any evidence of past life preserved in sediments or rocks.
What is a fossil.
200
Name the 5 gasses released during a volcanic eruption
What are
Carbon Dioxide
Sulfur Dioxide
Water Vapor
Hydrogen Chloride
Nitrogen
300
The shaking you feel from an Earthquake is due to this
What is the sudden release of stored energy.
300
The amount of space an object takes up.
What is volume
300
The record of past orientation and polarity of Earth's magnetic field recorded in rocks containing magnetite, such as Basalt.
What is Paleomagnetism.
300
This scientist was the first to believe that the continents moved. His evidence was the puzzle like fit of the continents as well as similar fossils and mountain ranges found on continents separated by oceans. He believed the material below the Earth's crust was slowly flowing.
Who is Alfred Wegner
400
Please name the four layers of the Earth in order from the surface to the center. Please include their make-up.
What is the crust-solid, the mantle-plastic, the outer outer-liquid, the inner core-solid.
400
If you increase the temperature of an object how does this affect an objects density
What is decrease density. It does this by adding energy to the atoms which causes them to make faster and spread out. Increasing the volume(not the mass). This changes the ratio of mass to volume, thus changing the density.
400
This happens when an Oceanic plate converges with a Continental Plate
What is subduction.
Bonus 100points Which plate subducts and why?
400
These deposits are used as evidence of continental drift. They are only created in swampy, tropical regions.
What are Coal Deposits
Bonus* 200 points How are they used as evidence?
400
This gas affects Earth in two ways after its release from a volcano. Being more dense than air it can cause suffocation of near by humans and animals. It also has a global affect. It can raise the global temperature after a volcanic eruption by trapping solar radiation received from the sun.
What is Carbon Dioxide.
Bonus* Does is warm the Earth immediately after a volcanic eruption? Explain.
500
THe theory that explains that plates move about the Earth due to convection currents is called
What is the Theory of Plate Tectonics
500
Earth has three sources of its internal heat
What are radioactive decay in the core, meteorite impacts and heat from original formation (accretion)
500
When Pangea started breaking apart 200million years ago this ocean began forming. It is still getting larger today.
What is the Atlantic Ocean
500
What are the 3 main ecological regions?
What are Polar, mid-latittude, tropic
bonus* 100 points What ecological region is your community in?
500
Explain how Ash can affect Earth's climate.
When Ash is released from a volcanic eruption is gets trapped in the upper atmosphere where it can reflect the sun's solar radiation, cooling the surface of Earth.
