What is the definition of Scientific Theory?
A really good explanation for how something works supported by evidence
Is this layer the thinnest, thickest, or in-between thickness?
Thinnest
Where is this layer in the earth?
It is at the very center of the earth below the mantle
Is this the thinnest, thickest, or in-between layer?
In-between
Tectonic Plates are on/apart of this layer
Crust
What is the definition of evidence
A fact or truth that supports a claim, belief, or theory
What do we see on this layer?
Mountains, animal and plant life, oceans, volcanos.
This layer is the hottest, coolest, or in-between temperature layer
hottest
Is this layer hotter or cooler than the crust? Is it less or more dense than the crust?
Hotter and denser
How many tectonic plates are there?
15
What does oceanic crust mean?
the land below the ocean
The crust is divided into about _______% land and ________% ocean
30% land, 70% ocean
What is this layer made of?
iron and nickle
What is the mantle made of?
Made of solid rock, primarily peridotite rock which is composed of iron and magnesium.
which tectonic plate do we live on?
North American Plate
What does convergent mean?
When two tectonic plates are pushing toward each other.
The oceanic crust is mainly made _________ rock. The continental crust is mainly made of ___________ rock.
Basalt, Granite.
The outer core is liquid but the inner core is solid. Why is the inner core solid?
The pressure forces the atoms together.
What is the lithosphere?
The solid, brittle outer layer of Earth, made up of the crust and the upper mantle. The lithosphere is divided into tectonic plates that move slowly on top of the asthenosphere
What landform do we see when a OCEANIC and CONTINENTAL crust converge (push towards eachother)
Volcanic Arc
What does divergent mean?
How does the earth make new oceanic crust?
Two tectonic plates are pulling apart from each other.
The movement of this liquid layer causes earth's _______________ field
Magnetic
What is the asthenosphere?
The warmer, stretchy layer of the upper mantle that lies below the lithosphere. The asthenosphere is solid but has a thick, sticky consistency and can flow like toothpaste
What landform do we see when two CONTINENTAL plates converge (push towards eachother)
Mountains
