  • Q10
    When the Earth was molten (melted) during its formation this type of material did what?
    Question Image
    Sunk to the middle layer since it was second most dense
    Floated to the top since it was the least dense
    Sunk to the center (core) because it was most dense

    Question Image
    Floated to the top since it was the least dense

  • Q13
    Each layer of Earth is different because of what reason(s)?
    Question Image
    Different material it is made of AND different density
    Different type of material it is made out of
    Whether or not the section is radioactive or not
    Different amount of pressure and temperature
    30s
  • Q14
    When the Earth was forming and molten (melted) it separated out into three layers due to what reason?
    Question Image
    The more dense materials sunk to the bottom. The least dense materials floated to the top
    The crust is made out of the most dense material since we must stand on it.
    The heavier materials sunk to the core. The lighter materials floated to the top.
    The core is radioactive. Above the core it is not. This causes a difference in temperature which separated the layers out
    30s
