Question

Which best supports the choice from Part A?


The crust is closest to the surface, which means it is the hottest.


The mantle contains minerals, which means it is solid.


The outer core is liquid metal, which means it is very hot.


The inner core is solid metal, which means it has magnetic properties.

Answer 1

I don’t have Part A — which layer did you pick?

Quick guide until you reply:
- If your Part A answer was mantle → pick: “The mantle contains minerals, which means it is solid.” (statement 2).
- If your Part A answer was outer core → pick: “The outer core is liquid metal, which means it is very hot.” (statement 3).
- If your Part A answer was crust → none of these support that (statement 1 is false — the crust is the coolest layer).
- If your Part A answer was inner core → none of these are a good scientific support (statement 4 is misleading — Earth’s magnetic field is produced by the liquid outer core, not a solid inner core).

Tell me your Part A choice and I’ll confirm the best support.
