earth
extreme greenhouse effect
venus
very thick and thin atmosphere
venus
consisting only carbon dioxide
venus
very thin atmosphere consistsly mostly carbon dioxide
mars
its atmosphere is made mostly of nitrogen
earth
the gaseous layer around planet
atmosphere
has an atmosphere field but not a magnetic shield
venus
water covers 70% of the planet
earth
has water frozen as ice
mars
may have once had running water
mars
may have escape out of atmosphere
venus
it has no moon
venus
it has two moons
mars
has almost no magnetosphere
mars
burst of radiation is deflected around earth
earth’s magnetic shield
created by earth’s core and rotation
earth’s magnetic shield
protection from the sun harmful radiation
earth’s magnetic shield
just enough gets through that helps us warm
earth’s magnetic field
venus has no ______ that allows oxygen to escape out into the space
electric field
the gaseous layer around planet that regulate temperature
atmosphere
all water found on eart
hydrosphere
oceans, lakes, rivers, streams, dew, water vapor, rain, clouds
hydrosphere
all ice found on earth
cryosphere
all gases found on earth
atmosphere
all living things found on earth
biosphere
three main categories of rocks
igneous, sedimentary, metamorphic
a state of matter that have definite shape and volume
solid
a substance is not a product of an organism but rather of earths physical processes.
inorganic compounds
identifies minerals as part of earths natural processes
naturally occurring
atoms arranged in order of increasing pattern
crystal shape
represented by chemical formula
specific chemical structure
color of mineral in powdered form
streak color
tendency of mineral to break along flat surface
cleavage
a manner breaks other than along planes of cleavage
fracture
is when a mineral breaks on a smooth, definite surface
cleavage
is when a mineral breaks unevenly or with rough break
fracture
this characteristics relates to the mineral density.
specific gravity
also known as double refraction
birefringence
some minerals display what is called phenomenon
fluorescence
magma freezes between
700c to 1250c
a mixture of many minerals
magma
it begin as magma
igneous rocks
light colored rocks that are rich in elements such as aluminum, potassium, silicon, and sodium
felsic
dark colored rocks that are rich in calcium. poor in silicon
mafic
cools quickly with little to no crystal
fine grained
takes longer to to cool, giving minerals more time to grow
coarse grained
magma pushes into surrounding rock below the earth surface.
intrusive igneous rock
forms when magma erupts onto earths surface
extrusive rocks
is formed by erosion
sedimentary rock
are moved from one place to another
sedimentary rock
the layers become compacted and cemented together
sedimentary rock
layers of rock
strata
the process in which sedimentary rocks are arranged in layers
stratification
are made of rock cemented togetheer with calcite or quartz
clastic
minerals crystallize out of solution to become a rock
NON CLASTIC
often called thermal metamorphism
contact metamorphism
no discernible source of heat
regional metamorphism
contain aligned grains of flat minerals
foliated
mineral grains are not arranged in plains or bands
non foliated
