made up of water droplets, dust, and smoke particles
cold-air clouds
made up of ice-crystals
ice-crystal clouds
white fuzzy edges
cumulus clouds
puffy with a flat bottom
stratus clouds
forming in layers
cirrus clouds
feather-like whispy shapes
water droplet clouds
sharp, distinct edges
cumulus clouds
dark, black, and thick
stratus clouds
creates fog
weather
state of the atmosphere
weather
causes change in the formation and interaction of air masses
water cycle
all water on Earth is recycled
wind
caused by the heating and cooling of air masses
high pressure area
indicator of good weather
low pressure area
indicator of bad weather
fronts
where storms typically happen along
atmospheric pressure
measure of the temperature, density, and amount of moisture in the air
hot air
type of air holding the most moisture
dew point
temperature at which the air is fully saturated and condensation occurs
sedimentary, igenous, and metamorphic
three types of rocks
igenous rocks
rocks likely to be found near a volcano
sedimentary rocks
rocks in layers
sedimentary rocks
make up 75% of all of the rocks
metamorphic rocks
form from pre-existing rocks due to heat and pressure
intrusive igenous rocks
larger crystals form in the rock
extrusive igenous rocks
smaller fine crystals form in the rock
metamorphic rocks
igneous rock form into what type of rock by heat and pressure
metamorphic rocks
flattened and aligned mineral grains in the rock
sedimentary rocks
bits of rocks, and plant and animal remains
andesite and diorite
rock examples formed from magma rock
sandstone and limestone
rock examples formed from layers of rock
quartz and calcite
rock examples formed from heat and pressure
magma
melted rock
rock cycle
rocks change from one type to another
color and luster
mineral properties easily noticed at first
hardness
measure of how easily a mineral can be scratched
pyrite
metallic luster and aka "fool's gold"
luster
light reflects from a mineral's surface
bright yellow
color of sulfur
diamond
hardest mineral on Earth and used as a reference mineral on Moh's scale
talc
softest mineral on Earth and used as a reference mineral on Moh's scale
streak
color of the mineral in powdered form
cleavage
minerals that break along smooth flat planes
fracture
minerals that break along rough jagged edges
color
least reliable indicator of a mineral's identity
streak
more reliable indicator of a mineral's identity than color
chemical reaction and double image
special properties used to test certain minerals
sedimentary rocks
fossils or remains of dead plant and animal material
lava
hot mixture found on the outside of the volcano
