What is the thickness of earth's layers?
the crust is the thickness of earths layers
How thick are the earths layers in km?
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
Do scientists think that movements in the liquid inner core create earths magnetic field?
The Earth's magnetic field is the result of electric currents in the liquid metal outer core.The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.See related links.
Is the earths mantle 3000 kilometers?
yes it is 2893 kilometers thick
How does the earths mantle differ from its crust?
Inner core: 2450 km thick Outer core: 2300 km thick Lower mantle: 2500 km thick Upper Mantle: 400 km thick continental crust: 30-70 km thick Oceanic Crust: 6 km thick
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.
Does the earth's inner core behave like a thick liquid?
No, the Earth's inner core is solid due to high pressure despite its high temperatures. The outer core, which is liquid, is responsible for generating Earth's magnetic field through convection currents.
Is the earths outer core a hot liquid?
yes it is The outer core of the Earth is a liquid layer about 2,266 km (1,408 mi) thick composed of iron and nickel which lies above the Earth's solid inner core and below its mantle
How thick is earths inner core?
The inner core is 1216 km and made of solid iron. It is approx 5000 degrees C and it doesnt melt because of everything else pushing down on it.
What is the thickness of earth's layers?
the crust is the thickness of earths layers
How thick are the earths layers in km?
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
What is the only part of earths inner structure that is a liquid?
The inner and outer core are made mostly of molten rock and lead, as the very center is solid because of the constant force. The thick mantle is liquid towards the center and is primarily considered to be solid. The outer core is what I would say to be the "only" liquid layer in Earth's structure as the inner core has too much pressure and the mantle had too little heat.
What is the thick rocky layer around earths core?
The core of the earth is surrounded by the mantle.The earth's core is called the inner core. Just outside that is the outer core, and it is liquid. Outside the liquid outer core is the mantle.
What are the characteristics of the earths outer core?
The Outer Core is made up of a liquid iron and nickel alloy. This creates the earth's magnetic field. It is in a liquid form due to the intense heat given off by the inner core (which is 5500C due to the decay of radioactive elements such as uranium inside) It is roughly 2300 metres thick.
Earths outer core?
The Earth's outer core is a liquid layer composed mainly of iron and nickel. It lies beneath the mantle and surrounds the solid inner core. The outer core is responsible for generating Earth's magnetic field through convection currents.
How many miles thick is the earths inner core?
The core of the Earth, about 4,216 kilometers across and 2635 miles, is thought to be divided into an outer core of liquid iron and a nearly solid iron inner core about 1,500 miles in diameter.
What are some physical characteristics of the earths outer core?
The Outer Core is made up of a liquid iron and nickel alloy. This creates the earth's magnetic field. It is in a liquid form due to the intense heat given off by the inner core (which is 5500C due to the decay of radioactive elements such as uranium inside) It is roughly 2300 metres thick.
