Igneous, Sedimentary & Metamorphic, oh my!
The two different kinds of igneous rock.
What is Extrusive and Intrusive?
An equation uses the mass of a mineral in air and mass of a mineral in water to find this answer.
What is specific gravity?
What is pyrite?
This scientist proposed that the Earth's continents had once been joined as a single landmass called Pangea.
Who was Alfred Wegener?
This type of seismic wave is known to be faster moving longitudinal waves.
What are Primary waves/P-Waves?
Metamorphism occurs here
What is an area of high pressure/temperature?
This describes the mineral's resistance to being scratched
What is hardness?
These two features are used to classify igneous rocks as extrusive or intrusive?
What are mineral crystal sizes and the presence of air holes?
This famous Californian fault is a well-known transform plate boundary.
What is the San Andreas fault?
These volcanoes are the most explosive with the most viscous lava.
What are Composite Volcanoes?
The meaning of "Igneous"
What is "born of fire"?
Through this process, atoms, molecules and ions are free to move about within molten rock. As the magma around them cools, these particles slow down and move closer together and combine forming compounds/minerals.
What is Crystallization of Magma or Lava?
These rocks are darker in colour because they contain many dark minerals such as amphibole, pyroxene, olivine and biotite.
What are Mafic rocks?
This research technology uses sound waves to map the topography and depth of the ocean floor.
What is Sound Navigation and Ranging (or S.O.N.A.R)?
This basaltic lava flow is classified due to its cooler temperature, quick hardening, jagged edges, large chunks and coral-like appearance.
What is aa?
The horizontal layering found in Sedimentary Rock.
What is Strata?
The crystal shape of NaCl.
Cubic
In the locating the epicentre of an earthquake in class assignment, this is what the intersection of all three circles represented.
What is the epicentre of the earthquake?
This type of plate boundary can be seen very clearly in Iceland and occurs when tectonic plates are being pulled apart.
What are Diverging Plate Boundaries?
This exponential scale can be used to measure the amount of energy released during an earthquake.
What is the Richter scale?
The metamorphic rock formed after the transformation of sedimentary sandstone.
What is Quartzite?
Imaginary lines called this are used to distinguish the six systems of crystals.
What are crystallographic axes?
This location on the locating the epicentre of an earthquake in class assignment had the longest amount of time in between the P-wave and the S-wave.
What is Balboa Heights?
This result of Oceanic-Continental covering plate boundaries where the oceanic crust sinks beneath the continental crust.
What is a mountain range?
This type of pyroclastic material are blobs of ejected lava larger than 64mm.
What are Volcanic Bombs?
