ASVAB Exam 69 Questions with Verified Answers 2022-2023
Geology - CORRECT ANSWER The study of the nature and composition of the rocks and material that
... [Show More] make up the Earth, how they were formed, and the physical and chemical processes that have changed earth over time
Mineral - CORRECT ANSWER a naturally occurring, inorganic solid that has a crystal structure and a definite chemical elements
Organic compounds - CORRECT ANSWER Carbon- containing remains of decomposed plant or animal matter
Mineraloids - CORRECT ANSWER Minerals that lack a defined crystalline structure.
3 fundamental classifications of rocks - CORRECT ANSWER Sedimentary
Igneous
Metamorphic
Sedimentary rocks - CORRECT ANSWER - Form at the Earths surface on land and bodies of water
- Formed through deposition and cremation of fragments of other rocks, organic matter, and minerals
Strata - CORRECT ANSWER layers of sediment that get pressed into a solid over time when more sediment settles on top
Sedimentary rocks are further classified as - CORRECT ANSWER - Clastic/Detrital
- Biochemical
- Chemical
-Other
Clastic/Detrital Sedimentary Rocks - CORRECT ANSWER Composed of other inorganic rocks or organic particles
Biochemical sedimentary rocks - CORRECT ANSWER Have an organic component like coal which is composed of decayed plant matter
Chemical sedimentary rocks - CORRECT ANSWER Form from a solution containing dissolved materials that became supersaturated and minerals precipitate out of solution. (example: Halite, or rock salt is an example of a chemical sedimentary rock)
Other Sedimentary Rocks - CORRECT ANSWER Rocks from fragments formed by asteroid or comet impacts or from fragments of volcanic lava
Igneous Rocks - CORRECT ANSWER Composed of molten material beneath the Earths surface called magma and are classified based on WHERE the magma cooled and solidified
Types of igneous rocks - CORRECT ANSWER intrusive (plutonic) and extrusive (volcanic), or hypabyssal
Intrusive (Plutonic) Igneous Rocks - CORRECT ANSWER Igneous rocks cool slowly beneath the surface, larger crystals. Tend to have coarse grain, a larger crystalline structure of their mineral constituents, and a rough appearance. (Ex. granite)
Extrusive (volcanic) igneous rocks - CORRECT ANSWER Forms from fast cooling, forms on the surface, small crystals or too small to see, smooth or fine grained appearance. (Ex. glassy obsidian)
Hypabyssal igneous rock - CORRECT ANSWER Formed at levels between intrusive and extrusive (just below the surface) they aren't nearly as common
Metamorphic rocks - CORRECT ANSWER Made when heat, pressure, or fluids change one type of rock into another type of rock (sedimentary, igneous, or other metamorphic rocks) caused by physical and /or chemical change
Metamorphic rock classification - CORRECT ANSWER foliated and non-foliated
foliated metamorphic rock - CORRECT ANSWER Layered or folded, which means they form from compression in one direction and result in visible or banding within the rock (Ex. gneiss or slate)
Non-Foliated Metamorphic Rock - CORRECT ANSWER Receive equals pressure from all directions and thus have a homogenous appearance (Ex. marble)
"other rocks" - CORRECT ANSWER rocks that cannot fit into the criteria of the three rock type category (ex. fossil)
Fossil - CORRECT ANSWER A rock formed from the remains or impression of dead plants or animals, does not fit into biochemical class of rock because fossils themselves are WHOLLY composed of organic material and only formed under strict conditions, although they are commonly found within sedimentary rock
plate tectonics - CORRECT ANSWER a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
Lithosphere - CORRECT ANSWER the rigid outer part of the earth, consisting of the crust and upper mantle.
Asthenosphere - CORRECT ANSWER The soft layer of the mantle on which the lithosphere floats.
How many major and minor plates? - CORRECT ANSWER 9-15 major
40+ minor
oceanic plates - CORRECT ANSWER Thin plates that form the ocean floor; more dense than continental plates.
continental plates - CORRECT ANSWER plates below the continents
Fault - CORRECT ANSWER The line formed by the meeting of two plates (San Andreas Fault where the Pacific and North America plates meet)
Convergent plates - CORRECT ANSWER tectonic plates that collide with each other
Divergent plates - CORRECT ANSWER Two tectonic plates that are moving away from each other, causes volcanic activity and magma escapes to the surface and solidifies, new land yasss
transform boundaries - CORRECT ANSWER Places where tectonic plates slide along beside one another in opposite directions, horizontally, as they move
Larger tectonic plates - CORRECT ANSWER - North American
- Eurasian
- Pacific
- Australian
- Antarctic
- South American
- African
- Indian
Pangea - CORRECT ANSWER A supercontinent containing all of Earth's land that existed about 225 million years ago.
Earths shape - CORRECT ANSWER slightly ellipsoid or oblong (like a football)
Earth is divided into 3 layers - CORRECT ANSWER crust, mantle, core
Crust and core - CORRECT ANSWER solid
Mantle - CORRECT ANSWER The layer of hot, solid material between Earth's crust and core.
convergant boundaries - CORRECT ANSWER plates can rise to mountain ranges
Subduction - CORRECT ANSWER One plate going under another plate, happens in convergent boundaries where oceanic and continental plates converge and the denser oceanic plate sinks below the continental plate
Hot spots can occur - CORRECT ANSWER within either continental or oceanic plates, when reaching the surface a volcano forms
Earthquakes are caused by - CORRECT ANSWER movement of tectonic plates/ sliding or colliding/ friction can cause an earthquake
Geography - CORRECT ANSWER the study of the earth's layout and features
Meridians - CORRECT ANSWER - vertical lines that measure east to west and are described as longitudinal.
- 15 degrees apart from one another
Prime Meridian - CORRECT ANSWER The first line or point of zero, serves as reference line
Horizontal - CORRECT ANSWER
