|
earth's solid crust lies over a layer of melted material, called
|
mantale
|
|
|
|
uneven heating causes material in the mantle to constantly and slowly rise and fallin a,
|
Convection Current
|
|
|
|
what is the rocky outer shell of earth, which is made up of the crust and rigid upper part of the mantle,
|
Lithophere
|
|
|
|
the earth has two kinds of crust, what are they,
|
continental crust and the oceanic crust
|
|
|
|
what occurs when the edges of plates meet,
|
plate boundaries
|
it has to do with boundaries
|
|
|
what forms where plates collideand the pressure produces mountains and bands of earthquakes and volcanic activity,
|
convergent boundary
|
it has to do with boundaries
|
|
|
the movement of one plate under another is called,
this happens at, |
subduction
converging plate boundaries |
it has more than one questen in it and has more than one answer
|
|
|
what forms when two plates diverge, or move away from each other,
|
divergent boundaries
|
it has to do with boundaries
|
|
|
most divergent boundaries are found in the oceans, they build mountain ranges called,
|
mid-ocean riges
|
|
|
|
what is where two plates slide past each other,
|
transforming boundaries
|
it has to do with boundaries
|
|
|
convergent Boundary
|
a convergent boundary froms where plates collide. the pressure and violence at convergent boundaries produces mountains and bands of earthquake and volcanic activity.
|
|
|
|
Divergent boundary
|
a divergent boundary forms when two plates diverge, or move away from each other. melted rock from the mantle can seep to the surface at divergent boundaries and form new crust.
|
|
|
|
Transforming boundary
|
a transforming boundary forms where two plates slide past each other.
|
|

what is the outer most layer of the earth?
|
Crust
|
|
|
|
what is the inner most layer of the earth?
|
innercore
|
|
|
|
what is the layer of the earths core?
|
outer core
|
|
|
|
what is the middle and the largest layer of the earth, and makes up 213 of the earths mass?
|
Mantle
|
|
|
|
what is the upper layer of the maltle, and is made of soft rock?
|
asthenosphere
|
|
|
|
new crust is forming at?
|
rift valley, Afica
|
|
|
|
new crust is formed at?
|
spreading boundaries
|
|
|
|
two plates meet at?
|
plate boundaries
|
|
|
|
the San Andreas fault in california is a?
|
fracture boundary
|
|
