Changes rock on the Earth's surface
weathering / erosion
-
After heat and pressure is applied to sedimentary Rock?
metamorphic rock
-
Slowly cooled magma results in what type of igneous rock texture?
Coarse-grained igneous rock
-
layers in sedimentary rock
strata
-
how are rocks classified?
composition and texture
-
type of sedimentary rock from fossils
organic (it was once alive)
-
arrangement of sedimentary rocks in layers
stratification
-
what forms sedimentary rock?
compaction and cementation
-
changes the Earth's surface by filing in and elevating
deposition and uplifting
-
igneous rock comes from
cooled magma
-
magma cooled beneath the Earth' surface
intrusive igneous rock
-
metamorphic rock with bands
foliated
-
rocks changing their shape
deformation
-
sediments that come to rest or is dropped off are called
deposition
-
rocks that have bends or folds are
deformed
-
changes a rock into metamorphic rock
heat and pressure
-
starting point of igneous rock
magma
-
most common of organic sedimentary rocks
fossils
-
corals become what type of sedimentary rock
organic
-
layering of sedimentary rock
stratification
-
metamorphic rocks without bands
nonfoliated
-
sediments are moved by
erosion
-
minerals in a rock determine its ______________ or what it is made of
composition
-
rock can change their composition during
the rock cycle
-
rock fragments that are cemented together by calcite or quartz
clastic sedimentary rock
-
sedimentary rock made of disolved minerals that eventually crystallize
chemical sedimentary rock
-
metamorphism that happens whem magma contacts rock
contact metamorphism
-
metamorphism that occurs when tectonic plates collide
regional metamorphism
-
what does nonfoliated rock have
no bands
-
forms limestone
remains of fossils or ocean dewellers
-
when rocks change in composition their crystals
recrystalize
-
Where does uplift take place
underneath the Earth's surface
-
Where does weathering take place
on the Earth's surface
-
Volcanic rock that cools quickly at the surface has what type of crystals
no crystals
-
Composition is
minerals that a rock is made of
-
texture is
appearance of the rock based on the arrangement of it's minerals
-
igneous rock that has cools slowly (crystals)
has large crystals (coarse grains)
-
What is deformation
rock that has been folded or bended, it is not in layers
-
Which would break easier a foliated or non-foliated rock
foliated, along it's band
-
What is stratification?
sediments laid down in layer after layer
-
in folliated rocks, their minerals are
arranged in bands or layers
-
in non-foliated rocks minerals are
recrystalized
-
how can rocks be changed
weathering, pressure, melting, cooling
-
Felsic rocks are lighter and contain
aluminum, silicon, sodium and potassium
-
Mafic rocks are darker and contain
iron, magnesium, and calcium
