Seismological study shows that the outer core will transmit compressional waves but will not transmit torsional or shear waves. That indicates that it it has no material strength, i.e. that it is a fluid.

∙ 9y agoThe outer core is thought to be molten because of the amount of pressure on it. It is simply not under enough pressure to be in solid form.

∙ 12y agoWe believe that Earth's core is liquid because it is too hot for anything solid to exist within that zone. Volcano magma and lava is proof of this.

Does earth's molten core affect gravity?
First: The earths core is not molten, it is a very dense solid mass, kept solid by the intense pressure on it. Second: It is the layer around this core that is molten, and yes it does influence gravity, but more so earths magnetism.
Which of the Earths layers is just below lower mantle?
The molten bit of the Iron core.
Is the earths core getting hotter or colder?
The earth's core, consisting primarily of molten nickel and iron, is cooling over time.
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
The convention that causes earths magnetic field happens in earths?
core
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
What area of earths interior is molten?
The outer core

What produces earths magnrtic field?
The spinning molten core.
What is the earths deeppest layer?
Its spinning, molten, liquid, iron core.
What do scientist produces earths magnetic field?
Its molten iron core.
Is Earth's inner core surrounded by a liquid outer core?
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
Which of the Earths layers is just below lower mantle?
The molten bit of the Iron core.
What do scientists think produces earths magnetic field?
Its molten iron core.
What molten metal forms the earths core?
The question's wrong there...the inner core is made out of SOLID iron and nickel. But if you were talking about the OUTER core, it is extremely runny and gooey iron and nickel and a piece of molten crust.
Why is iron the earths most abundant element?
It makes up the majority of the molten core of the earth.
Is earth's magnetism related to the circulation of molten material within Earths core?
TRUE (this is the correct answer)
