True/False Questions:
11.) outer core → layer of liquid metals that surrounds inner core
This is false. You gave no answer.
12.)
convergent boundry → a boundry that occurs when plates push into one another
This is false. You gave no answer.
13.)
convection → transfer of energy by movement of material
This is false. You gave no answer.
14.)
sea floor spreading → mid ocean ridges form cracks in earths crust, molten rock rises through
these cracks and cools, to form new crust
This is false. You gave no answer.
15.)
slab pull → earths thickest layer. Made of hot rock that is less dense then the core
This is true. You gave no answer.
It should be slab pull → when gravity pulls denser plates into astenosphere.
