Which material is more dense?
solid
liquid
gas
Convection cycles move in the mantle. How does this affect the crust?
crust has no motion
crust moves in random direction
crust moves in same direction convection cycle moves
What is magma made of?
solid rock
melted rock
small pieces of sediment
Density has to do with what two things?
Material and Volume
Mass and Volume
Mass and Density
Material and Density
Which state of matter is least dense?
Solid
Liquid
Gas
If magma increases in temperature (get hot) what will happen?
It moves down (sinks)
It moves up (rises)
If magma decreases in temperature (cooler) what will happen to the magma?
It will move down (sink)
It will rise up (float)
Why does hot mantle rise (go/move up)?
hot = less dense
hot = no change
hot = more dense
Transform boundary move in what direction?
Away from each other
They collide
Slide past each other
Create mountians
What direction do Divergent plates travel?
North and South
East and West
Towards each other
Away from each other
Convergent plates move in what direction?
North and South
They slide past each other
They move towards each other
They move in opposite directions
Which layer of Earth are the tectonics plate found in?
lithosphere
asthenosphere
A plate boundary where two plates slide past each other in the opposite direction
Sea floor spreading
Lithosphere
Transform Boundary
Convergent Boundary
The region where oceanic plates sink down into the asthenosphere.
Asthenopshere
Subduction Zone
Lithosphere
Transform Boundary
The formation of new areas of oceanic crust, which occurs through the up-welling of magma at mid-ocean ridges and its subsequent outward movement on either side.
Transform Boundary
Divergent Boundary
Sea Floor Spreading theory
Plate Tectonic Theory
The idea that continents slowly shift their positions due to movement of the tectonic plates on which they ride
Sea Floor Spreading Theory
Continental Drift Theory
Plate Tectonic Theory
Plates of Plates Theory
The theory that the lithosphere is broken up into large plates that move and then rejoin; considered the unifying theory of geology
