The circulation of the outer core, driven by heat from the inner core, generates Earth's magnetic field through a process known as the geodynamo. This magnetic field plays a crucial role in protecting the planet from harmful solar radiation and helps in navigation by providing reference points for compasses.

Does In the outer core flows water currents?

No. The outer core is made of iron and a lighter element, probably nickel. There is no free water in the outer core. But the outer core is liquid, and that liquid does circulate ("convection"). That circulation is what generates the magnetic field.


Compare and contrast outer and inner cores?

The inner core is solid.The outer core is liquid.It may seem odd that the hotter, inner core is solid while the outer core is liquid magma, but in the inner core you have the entire pressure of the earth pushing down on you.The outer core is hot, molten iron and nickel under extreme pressure. Convection currents cause movements in the liquid outer core. Scientists hypothesize that these movements cause Earth's magnetic field. The outer core surrounds the inner core, which occupies the center of Earth. The inner core is also iron and nickel and is also extremely hot. But pressure within the inner core is so great that it remains a solid.


What cause contenital drift?

Probably conduction currents in the magma of the outer core.


What cause the earth magnetism?

The inner core and outer core of the planet are composed primarily of iron and nickel. The outer core is liquid and the inner core is solid. It is thought that the convective motion of the liquid outer core is responsible for generating the main field. Recent studies indicate that the inner core of the Earth may rotate a bit faster than the outer core and it is possible that this rotation may be associated with field reversals.


What is thicker inner or outer core?

The outer core is thicker than the inner core. The outer core is about 2,260 kilometers thick, while the inner core is approximately 1,220 kilometers thick.


Does the inter core have more pressure then the outer core?

Yes, Inter core has more pressure than outer core and that's why outer core is solid, because there is not enough pressure in outer core.


Where the outer core is locate?

the outer core is located next to the innner core

Are the inner and outer core of earth the same?

No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.


Which layer of earth is made up of liquid metal?

the outer core


What does the outer core look like?

The outer core is at 1,800 - 3,200 miles (2,890-5,150 km) below the earth's surface. The outer core is liquid and mainly consists of iron, some nickel and about 10% sulphur and oxygen. The temperature in the outer core is about 7200 - 9032 ºF (4000-5000ºC). The density of the outer core is between the 10g/cm³ and 12,3g/cm³. The outer core and inner core together cause the earth's magnetism.


Why is the inner core and the outer core separated into two layers if they are made of exactly the same material?

'Cause they ARE made of different things
