Geology 101 exam 1 WWU
Characteristics of a mineral - ✔️✔️Naturally occurring,
solid,
crystal structure-atoms are arranged in a regular, repeating way
inorganic processes,
definite chemical composition
What is a continent-continent convergent boundary? - ✔️✔️When two continental
masses collide
Often requires subduction of ocean plate in between masses
oceanic lithosphere - ✔️✔️lithosphere that is mainly comprised of basalt; it is more
dense that is why it sits lower in the asthenosphere.
-thin
-young(200 myo)
Where is new ocean lithosphere created? - ✔️✔️mid-ocean ridges (divergent plates)
What is a hydrothermal vent? - ✔️✔️an opening in the sea floor out of which heated
mineral-rich water flows.
Where do most earthquakes in the ocean occur? - ✔️✔️mid-ocean ridges
, What is a divergent boundary? - ✔️✔️the place where two plates move apart, or
diverge; mostly occur along mid-ocean ridges and land
magma fills space between plates
What is a convergent boundary? - ✔️✔️When two plates collide and one plate
subducts
What is a transform boundary? - ✔️✔️a place where two plates slip past each other,
moving in opposite directions
What is an ocean-continent convergent boundary? - ✔️✔️Ocean plate subducts under
continental plate
Creates a trench and volcanoes on continental plate
What is continental rifting? - ✔️✔️When a divergent boundary forms within a continent
What is an example of continental rifting? - ✔️✔️Great Rift Valley in East Africa
What is Ocean-Ocean Convergent Boundary? - ✔️✔️The denser oceanic plate
subducts under the lighter one
Creates a trench and volcanoes(islands)
What type of boundary creates volcanoes? - ✔️✔️Ocean-Ocean Convergent Boundary
What type of boundary creates huge mountain ranges such as the Himalayas? -
✔️✔️continent-continent convergent boundary
Where is limestone made? - ✔️✔️bottom of the ocean floor
What type of boundary is the San Andreas Fault? - ✔️✔️transform boundary
What type of earthquakes at transform boundary? - ✔️✔️shallow earthquakes
Which type of plate boundary creates the largest earthquakes ever recorded? -
✔️✔️Convergent Plate Boundary
What is a hot spot volcano? - ✔️✔️an isolated volcano not caused by movement at a
plate boundary, but rather by the melting of a mantle plume
