What would earth lack of earth didn’t have a liquid outer core? it’s gravitational pull it’s magnetic field it’s geometric shape it’s chemical composition

Our liquid outer core is formed by mostly molten metals. Since the metals it is formed by, posess magnetical properties, we can conclude, that the earths liquid core does affect our magnetic field.

Since the highest concentration of metals is in the core, we could say, earth would lack a magnetic field, since only the metal located on the surface, wouldn't be able to do such thing.

Hope it helped,

Happy homework/ study/ exam!
