What two features of the magnetic field do magnetic iron-bearing minerals that crystallize out of
  magma record? What will be an ideal response?

Question 2

What is it about a cooling lava that allows geologists to determine the location of past magnetic poles? What will be an ideal response?

Answer to Question 1

The minerals record the strength and direction of the Earth's magnetic field at the time of
crystallization.

Answer to Question 2

Iron-bearing minerals in a cooling lava align themselves in the direction of the current magnetic field
as they cool below the Curie Point.
