There are two types of seismic body waves that travel through the earth when an earthquake occurs. P-waves and S-waves. When an earthquake occurs it has been observed that there is a zone at the opposite side of the earth where P-waves are detected but S-waves are not. S-waves are not able to travel through liquids where as P-waves can and as such it is believed that the shadow zone is caused by the presence of a liquid outer core.

What is the state of earths outer core?
Earth's outer core is primarily composed of molten iron and nickel. It is in a liquid state due to the high temperatures and pressures found in the Earth's interior. The movement of this molten outer core is responsible for generating the planet's magnetic field.
What is the layer just above the earths center?
The layer just above the Earth's center is the outer core. It is composed of molten iron and nickel, and it surrounds the solid inner core. The outer core is responsible for generating the Earth's magnetic field.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
The convention that causes earths magnetic field happens in earths?
core
Which of the Earths layers is just below lower mantle?
The layer just below the lower mantle is the outer core. This layer is composed of liquid iron and nickel, and is responsible for generating Earth's magnetic field.
What area of earths interior is molten?
The outer 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
How do you know earths outer core is liquid?
Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
What is the depth earths outer core?
The Earth's outer core is a molten layer primarily composed of iron and nickel. Its outer boundary lies 2,890 kilometers beneath Earth's surface.
What is the state of earths outer core?
Earth's outer core is primarily composed of molten iron and nickel. It is in a liquid state due to the high temperatures and pressures found in the Earth's interior. The movement of this molten outer core is responsible for generating the planet's magnetic field.
Is the earths outer core made out of basalt or granite?
Neither. The Earth's outer core is primarily composed of molten iron and nickel. Basalt and granite are rock types found in Earth's crust, which is above the outer core.
What is the layer just above the earths center?
The layer just above the Earth's center is the outer core. It is composed of molten iron and nickel, and it surrounds the solid inner core. The outer core is responsible for generating the Earth's magnetic field.
What is the earths outer core?
The outer core is a liquid that is in between the inner core and mantle. It is 2,000km thick.
Is molten iron and nickel in the outer core spinning?
Yes! The molten iron and nickel in the outer core is spinning.
Is the core of the earth molten?
Part of it is. The outer core is molten while the inner core is solid.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
