ROCKS
100
A Convergent Boundary
Where 2 tectonic plates push against each other.
100
DAILY DOUBLE! Process of heat and pressure to form these rocks.
What is the process in which metamorphic rocks are made?
100
this is the second layer of earth's layers
What is asthenosphere
100
a solid inorganic substance of natural occurrence.
What are minerals?
100
These make up rocks
What is a mineral?
200
Divergant Boundaries
What are boundaries where tectonic plates pull apart?
200
Layers of sediment pressed together and glued by minerals and water under the ocean.
What is the process in which sedimentary rocks are formed?
200
this is a geologic activity (the ring of fire)
What is volcanic eruption
200
A rock a where a geologist would usually find a fossil.
What is sedimentary (rocks)
200
DAILY DOUBLE! These make up earth's lithosphere BUT can range to be various sizes, even a grain of sand
What are rocks
300
rocks formed outside of earth
What are extrusive rocks?
300
the reason why a scientist might find the same fossil on opposite sides of the ocean
What is the Theory of Continental Drift?
300
rocks formed inside earth
What are intrusive rocks?
300
Intrusive igneous rocks
What Is rocks with large crystals that cool slowly within the Earth?
300
this type of rock is formed during seafloor spreading
What are igneous rocks
400
destructive geologic activity (ring of fire)
What are earthquakes?
400
with heat from intense weight of rocks and pressure
What process creates metamorphic rock?
400
this method of heat transfer causes tectonic plates to move
What are convection currents in the asthenosphere?
400
this scale is used to tell the hardness of a rock
What is moh's hardness scale
400
The two things that happen for sedimentary rocks to become what they are
What is weathering and cementation?
500
this is a convergent process, involves magma, and is always underwater usually occurring in a mid ocean ridge.
What is seafloor spreading?
500
Molten rock inside the Earth.
What is magma?
500
The rate of this determines crystal size in rocks
What is cooling time?
500
this tests to see what color comes when you rub a rock against a tile.
What is a streak (test)
500
extrusive rocks with no crystals that cool fast in air on top of the Earth
What are glass like rocks that look smooth like glass?
