Geology Exam Crossword Puzzle

QUESTIONS LIST:

• phaneritic: a texture of igneous rocks that have cooled slowly in the earth, can see visible crystals.
• aphanitic: a texture of igneous rocks that have cooled fairly fast but not fast enough to form big crystals.
• luster: the shine a mineral takes on, based on the way light reflects off of a mineral, typically divided into two main categories: metallic and nonmetallic.
• glassy: texture of an igneous rock that has instant contact with water or air.
• vesicular: an extrusive rock filled with small bubble structures, frozen in place as gases escaped from the cooling lava.
• potassium feldspar: a mineral with a light reddish-brown color that is present in felsic minerals.
• halite: a mineral that is distinguished by its 90-degree cleavage.
• calcite: a mineral that is distinguished by its 60-degree cleavages (parallelogram)
• plagioclase feldspar: a mineral that is distinguished by the presence of striations.
• cleavage: the way a mineral “splits” into smaller bits of characteristic shape.
• fracture: when a mineral breaks irregularly.
• effervescence: the property of a mineral where when in contact with hcl, the mineral fizzes.
• mafic: potassium feldspar, quartz, and plagioclase feldspar are dominant minerals of what type of rock compositions?
• felsic: olivine, augite, and plagioclase feldspar are dominant minerals of what type of composition?
• volatile: melting that occurs at subduction zones.
• decomposition: melting that occurs when pressure is decreased.
• thermal: melting that occurs when heat is increased.
• east african rift: where is an example of a location where continental rifting takes place?
• antarctica: where is an example of a location where the step weathering, erosion, and beveling takes place?
