7-10
Almost all minerals are i__________?
invisible
inorganic
imbeciles
illuminating
All mineral are N____?
Nosy
Nice to look at
Naturally occurring
Nonsilicates
Minerals can be a pure substance or a mixture.
TRUE
FALSE
Minerals have a definite chemical composition.
TRUE
FALSE
A rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock?
Magma
Igneous
Metamorphic
Sedimentary
In the Starburst Lab, we made models of all types of rocks. Which type of rock is able to turn into a metamorphic rock?
Only sedimentary
Only igneous
Both igneous and sedimentary
Neither igneous or sedimentary
Extrusive Igneous
Intrusive Igneous
A student analyzing an unknown rock
that formed on Earth's surface observes
that the rock has no layers, no individual
particles or crystal grains, and is smooth
and glassy. The unknown rock is most
likely classified as
intrusive igneous rock.
extrusive igneous rock.
intrusive metamorphic rock.
extrusive metamorphic rock.
Listed below are six minerals along with their hardness as determined by the Mohs hardness scale:
Alabaster 2.0
Boracite 7.5
Creedite 4.0
Ekanite 5.5
Moissanite 9.3
Spectrolite 6.0
Using the list, which minerals will scratch Ekanite?
Boracite, Spectrolite, and Moissanite
Alabaster and Creedite
Boracite and Moissanite
Alabaster, Moissante, and Creedite
The composition of rock X is:
60% clay
15% gravel
25% sand
Rock X is most likely
organic rock
igneous rock
metamorphic rock
sedimentary rock
When rocks are broken into smaller pieces they are then moved by things such as water or wind. This movement of rock is called...
Weathering
Deposition
If a scientist is observing rocks near a volcano, she is most likely observing what kind of rock?
igneous rock
sedimentary rock
sediment
metamorphic rock
The forces that create metamorphic rock are related to which of the following?
The breaking of rock into smaller particles over long periods of time
extreme heat and pressures
The cooling of magma above Earth’s surface after a volcanic eruption
The transportation of Earth materials by moving water
Rock sediments are carried to other places by the wind, running water, and gravity. As these forces lose energy settling takes place. The sediments settle out of the air or water in rock particles graded by size with heavier pieces settling out first. Which term best describes this process of sedimentary rock formation?
weathering
erosion
deposition
melting
Which of the following describes rocks formed when sediments are buried, compacted, and cemented together?
Clastic
Organic
Foliated
Nonfoliated
Which rock can shale transform into by heat and pressure and minerals are arranged in bands/planes?
nonfoliated metamorphic
foliated metamorphic
organic sedimentary
intrusive igneous
Use the chart to answer this question. A student has a mineral that she wants to identify. It is green in color, has a glassy luster, and has a hardness of 5. Based on the information in the table, the mineral the student is testing is most similar to
Calcite
Fluorite
Apatite
Topaz
Use the chart to answer this question. Which mineral contains the greatest variety of elements?
Calcite
Feldspar
Mica
Minerals form naturally from all the following processes EXCEPT:
Precipitation in water solutions
Plant decomposition
Magma cooling
Use the chart to answer this question.
True or False: A piece of glass can be scratched by quartz, but not by calcite
True
False
A mineral is a substance that...
(check ALL that are TRUE)
Is created from rocks
Is formed in nature
Is ONLY formed from ONE element
Has as specific chemical identity
Is a solid
How is it possible to have two DIFFERENT minerals that have the SAME chemical makeup?
Each one has a different crystal structure
One is formed by living things, the other below the ground
One is as solid while the other is a liquid
One was formed in nature and the other in a lab
How are clastic rocks formed?
minerals dissolve in a solution & then crystallize
rock fragments are squeezed together
remains of plants & animals are deposited in thick layers
What are the four layers of the Earth from inside to the outside?
Crust, Outer core, mantle, inner core
Inner core, outer core, mantle, crust
crust, mantle, outer core, inner core
Mantle, outer core, inner core, crust
What materials make up the inner core?
copper and nickle
iron and nickle
metal and copper
water and nickles
