Explanation / Answer

1. Answer is Option d. It becomes hotter with greater mineral density and greater pressure

Earth's core is much hotter than its surface and the gravity is less, so the pressure will be more.

Also, when we move towards the core, we get heavier elements with high density.

With increasing depth from the earth surface the temperature and pressure will increases this phenomenon is called geothermal gradient

2. Answer : b, outer core

Outer core is the region where the earth's magnetic field is originated

Outer core is essentially made-up of iron and is in liquid state, convection currents or the flow of liquid in the outer core generates electrical currents and hence the magnetic field.
