Question

which event would most likely occur if earth did not retain the heat from its formation?
the inner core would liquefy.
seismic waves would move the crust.
the earths magnetic field would disappear.
the asthenosphere and outer core would solidify.

Explanation:

The heat from Earth's formation helps keep the asthenosphere and outer - core in a semi - molten or molten state. Without this heat, they would cool and solidify. The inner core is solid due to high pressure, not just heat from formation. Seismic waves moving the crust is related to tectonic activity and earthquakes, not directly to retained formation heat. The Earth's magnetic field is generated by the movement of molten iron in the outer core, which is driven by heat, but the most immediate effect of losing formation heat would be the solidification of the asthenosphere and outer core.

Answer:

The asthenosphere and outer core would solidify.
