Answer:

Q.1. Crust / Lithosphere<u>, </u> Q.2. Outer Core,  Q.3. Mafic from bottom to top

Explanation:

This rigid layer includes the brittle upper portion of the mantle and the crust.

The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.

Most shield volcanoes are mafic in composition.
