Total questions: 12
Worksheet time: 11mins
Where do convection cycles happen?
core
mantle
crust
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
What layer of earth changes because of the convection cycle?
Crust
Core
Mantle
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)
How does density relate with viscosity?
more dense, higher the viscosity
less dense, higher the viscosity
Which has a higher viscosity?
Oil
Honey
Why does hot mantle rise (go/move up)?
hot = less dense
hot = no change
hot = more dense
