Rock and Roll
An igneous rock that is relatively light in color due to the fact that it is rich in feldspar and quartz
What is a felsic rock?
He was the whipper-snapper meteorologist who suggested the hypothesis of continental drift
Who was Alfred Wegener?
It is the measurement of the amount of kinetic energy in an earthquake
What is magnitude?
The imaginary ring that marks the plane along which all planets orbit the sun
What is the ecliptic?
It's a pure substance made entirely out of the same kind of molecule
What is a compound?
The sedimentary rock shown here
What is coquina?
The type of stress found at transform boundaries
What is shearing?
The process used to locate the epicenter of an earthquake
What is triangulation?
The lunar phase shown here
What is a waning crescent?
The number of collisions between air molecules and anything else they bump into
What is air pressure?
This determines the size of crystals that forms in igneous rocks
What is the cooling rate of the magma or lava?
The movement in the asthenosphere that causes plates to drift
What is a convection current?
A thick cloud of ash, molten rock, and poisonous gases that flow down the slope of a volcano
What is a pyroclastic flow?
It's defined as inertia and gravity working together to keep an object in it's revolutionary path
What is orbital motion?
The process of changing a substance from the gas phase back to the solid phase
What is deposition?
The presence of this often helps to distinguish a rock as metamorphic
What is foliation?
The changes in the alignment of iron on the ocean floor that helped prove seafloor spreading
What is magnetic striping?
The formation of mountains
What is Orogeny?
They occur at the two times a year when the ecliptic and the celestial equator are furthest apart
What are the solstices?
It's what causes wind
What is more dense air moving to an area of less density?
Naturally occurring, crystal-like substances that are the building blocks of most rocks
What are minerals?
The geological structure into which subduction occurs
What are deep ocean trenches?
Type of magma that results in explosive volcanic eruptions
What is rhyolitic magma?
The type of solar eclipse characterized by the moon being close to Earth so its lunar disk does not completely block out the sun, thus forming a ring of light
What is an annular eclipse?
The three things that can be changed to affect the density of air molecules
What are mass (number of molecules), volume, and energy level?
