What happens when we warm up water in a pot?
More kinetic energy- less volume- less density- molecules rise up
More kinetic energy- more volume- less density- molecules rise up
More kinetic energy- less volume- more density- molecules rise up
What happens when water reaches the top of the pot?
Molecules cools down- more kinetic energy- less volume- more dense- falls down

What are the characteristics of the mantle that permit it to produce convection currents?
It is hot and elastic
It is a kind of mushy, spongy state
It is not quite liquid, but not quite solid state, kind of plastic
The part of the mantle where convection currents occur is the astenosphere
What if the mantle solidified?
No convection currents, no plate movement
No convection currents, no earthquakes
No convection currents, no volcanism
