Unit 3: Composition of the Earth Flashcards
Which rock type is formed from heat and pressure as well as during continental-continental convergence.
metamorphic rock
process that moves sediment from one location to another location
erosion
what changes the composition of rocks
chemical weathering
what rock contains minerals or metals that have economic usefulness
ore
where would you find breccia rocks
steep slopes
where would you find green and black shale
marine deposits
where would you find coal
delta
where would you find conglomerate rocks
braided streams
is a hard, colorful mineral with a glassy or shinny luster
gemstone
list the characteristics used to identify a minerals
naturally occurring
solid
inorganic
have a set chemical formula
have a specific structure
used to identify an unknown mineral using an unglazed porcelain
streak test
A mineral that has a Mohs Harness of 5 can be
can be scratched by glass, but not by an iron nail
rock type formed through weathering, erosion, deposition, and lithification
sedimentary rock
Chalk dissolved by vinegar is a form of
chemical weathering
List of possible minerals you could see on the test
quartz
graphite
galena
amethyst
the term that means that the process that happen on Earth today can be used to understand how the Earth worked in the past
uniformitarianism
rock type that contains fossils, halite minerals and can be made from sandstone, silt and clay cemented together
sedimentary rock
igneous rock is formed
when magma, lava or molten rock cools
the three rock types
igneous rock
metamorphic rock
sedimentary rock
What exposes rocks to erosion thus creating sedimentary rocks?
tectonic plates
What is used to classify igneous rocks?
silica minerals
places where extrusive igneous rock is found
subduction zones
hot spots
mid-ocean ridges and spreading centers
place where are metamorphic rocks are often formed
convergent boundaries
luster is described as
metallic
glassy
waxy
