1What happens when we warm up water in a pot?
- AMore kinetic energy- less volume- less density- molecules rise up
- BMore kinetic energy- more volume- less density- molecules rise up
- CMore kinetic energy- less volume- more density- molecules rise up
2What happens when water reaches the top of the pot?
- AMolecules cools down- more kinetic energy- less volume- more dense- falls down
- BMolecules cools down- less kinetic energy- less volume- less dense- falls down
- CMolecules cools down- less kinetic energy- less volume- more dense- falls down
3What are the characteristics of the mantle that permit it to produce convection currents?
- AIt is hot and elastic
- BIt is a kind of mushy, spongy state
- CIt is not quite liquid, but not quite solid state, kind of plastic
4The part of the mantle where convection currents occur is the astenosphere
- AVerdadero
- BFalso
5What if the mantle solidified?
- ANo convection currents, no plate movement
- BNo convection currents, no earthquakes
- CNo convection currents, no volcanism
