Earth's Layers
The lithosphere is apart of this earth layer.
Crust
When plates move apart from each other we call this a _____________ plate boundary.
Divergent
Sediments need ___________ and ________________ in order to be _______________ and ______________ to form sedimentary rock.
Sediments need weathering and erosion in order to be compacted and cemented to form sedimentary rock.
What are the two classifications of igneous rock?
Extrusive (forms above earth's surface)
Intrusive (forms below earth's surface)
What was the name of the Volcanologist in "Fire of Love"?
Maurice Krafft
What state of matter is the mantle made out of?
(Solid, liquid or gas?)
Liquid AKA magma!
When continental crust DIVERGES from continental crust a _______________________ forms.
Valley
How can a sedimentary rock become a metamorphic rock?
Getting the right amount of heat and pressure underneath Earth's surface
Limestone and Calcareous Tufa
What was the name of the Geochemist in "Fire of Love"?
Katia Krafft
What do we call the place where two tectonic plates meet?
Plate Boundary
What kind of plate boundaries do Grey volcanoes form at? and What type of crust is ALWAYS needed for a grey volcano to form?
Convergent plate boundaries. You always need at least one piece of oceanic crust.
Explain how an igneous rock is made.
Hot magma cools and forms rock above Earth's surface (extrusive) or below Earth's surface (intrusive)
What is one clue that a rock is metamorphic?
Foliation: look for the stipes/bands/layered appearance on the rock
What is the name of the final volcano showcased in the film?
Mount Unzen
Hottest earth layer
Inner core
Continental crust is (more dense or less dense) than oceanic crust because it has more (silica or iron).
Less dense
More silica
Increasing level of Metamorphism:
Shale -> Slate -> _______ -> Gneiss
Schist :)
Name a large grained igneous rock.
Is it intrusive or extrusive.
Granite is intrusive
What are the two types of volcanic classifications?
Which one is the "killer" and why?
Red and Grey
Grey because they are explosive and release ash, volcanic bombs, and pyroclastic flow.
Why do the tectonic plates move?
(hint: it might help to think about what fuels the movement)
What landform is made?
Mid Ocean Ridge
I have large grains, am not organic, and have a tan/grey/red color.
What rock am I?
Conglomerate
I am foliated, small-grained, and grey in color.
What rock sample am I?
Foliated tells you it's metamorphic.
Our only small-grained metamorphic rock is SLATE.
What do the scientist say a "volcanic bomb" is?
a large fragment of partially molten rock ejected from a volcano during an eruption
