OUTSIDE EARTH
this force causes a convergent boundry
What is compression
DAILY DOUBLE! useful to scientists (i repeat scientists) to help them find the order of rock layers.
What is an index fossil
this is the second layer of earth's layers, sits beneath the lithosphere
What is asthenosphere
geologists use these to help them order rock layers
What is fossils
These make up intrusive igneous rocks
What are large crystals
these two geologic category names name destroyed and created land
What is constructive or destructive
fossils are this compared to the age of the rock they are in
What is same age
this is a constructive geologic activity (the ring of fire)
What is volcanic eruption
this is the rock a geologist would usually find a fossil in
What is sedimentary (rocks)
DAILY DOUBLE! These make up earth's lithosphere BUT can range to be various sizes, even a grain of sand
What are rocks
rocks formed outside of earth
What is extrusive
the reason why a scientist might find the same fossil on opposite sides of the ocean
What is the theory of plate tectonics
rocks formed inside earth
what are intrusive (rocks)
the 6 parts needed in an investigation involving the scientific method. (geologists always do this)
What is observe, question, hypothesize, experiment, results, and conclusion.
this type of rock is formed during seafloor spreading
What are igneous rocks
destructive geologic activity (san andreas fault)
What is earthquakes
the rock that is made with heat and pressure
What is metamorphic
this causes plates to move
What is convection currents in the asthenosphere
this scale is used to tell the hardness of a rock
What is moh's hardness scale
The two things that happen for sedimentary rocks to become what they are
What is weathering and compaction
this is constructive, involves magma, and is always underwater, atlantic ocean
What is seafloor spreading
the phase of the asthenosphere
What is a liquid?
determines crystal size in rocks
what is cooling time
this is the term used for describing the physical and chemical properties of rocks.
What is petrography.
this is a characteristic that are used to classify metamorphic rocks
What is wavy bands
