100
The stage in a star's life-cycle that it is most stable as it fuses hydrogen to helium in nuclear fusion.
What is a main sequence star?
100
The flattened, rotating disk that is the 1% of unused dust and gas that forms around a still-developing star.
What is a protoplanetary disk?
100
The two tectonic plates that are subducting under New Zealand.
What are the Pacific and Australian Tectonic plates?
100
The large, vertical displacement of water leading to huge amounts of kinetic energy travelling through the water in all directions.
What is a tsunami?
100
At a converging plate boundary, the most dense plate will sink down into the mantle, under the plate that is less dense.
What is a subduction zone?
200
Spectral Classification that is given to the hottest, blue stars.
What is the O spectral class?
200
The accumulation of layers or material due to the pull of gravity and friction caused by resulting collisions.
What is the natural process of accretion?
200
The ground atop the focus of an Earthquake.
What is the epicentre?
300
H-R diagrams allocate star placements dependent on the factors that line the edges of the diagram.
What is luminosity, Magnitude and Temperature?
Point Bonus of 100 points if Spectral Class is mentioned.
300
(Full Explanation Required)
The collision hypothesis.
What is the theory that describes: A mars-sized body collided with a young Earth which bad thrust debris into our orbit which eventually accreted together, forming our moon?
300
Due to a combination of water saturation and intense shaking, soil will behave more like a liquid than a solid.
What is liquefaction.
400
The factor that leads to the changing of a star's temperature, size, colour, chemical composition over its life-cycle.
Point Bonus Requirement: List all associated elements used in nuclear fusion.
What is the element being used in nuclear fusion?
Point Bonus of 150 points if all listed elements are correct:
H , He , C , (Ne + O) , Mg + (S) , (Fe) + Ni
400
Solar winds generated by the initiation of Nuclear Fusion force lighter materials out past a certain this threshold in which a star's light has no effect.
What is the frostline?
400
In a breakage in the crust, rocks horizontally slip past each other often catching upon each other, leading to a build up and release of elastic potential energy as seismic waves in Earthquakes, when they attempt to move.
What is a strike-slip fault?
500
This star is 8-25 mass of the sun, extremely hot, big, blue and it has passed its most stable life-cycle stage. At the end of its life-cycle, what will it be?
What is a neutron star?
500
The stage in which a developing-planet has become the gravitationally dominant object within its orbit, triggering a bombardment of nearby materials onto its surface.
What is Late bombardment?
500
The horizontal sliding of tectonic plates at boundaries that sometimes lead to getting caught on each other and result in shallow Earthquakes
What are transform boundaries?
