it is 200,900,234,123,666 miles
The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.
The inner core is approximately 1271 kilometers in radius and is composed of iron and nickel, the liquid outer core is 2270 kilometers radius, and the radius of the mantle, the thickest solid layer, is 2885 kilometers.
The mantle is divided into the upper mantle and the lower mantle. The upper mantle lies directly beneath the Earth's crust and extends to a depth of about 410 miles. The lower mantle extends from the bottom of the upper mantle to a depth of about 1,800 miles.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
It is believed to be approximately 758-780 miles (1219 - 1250 km)
The inner core is approximately 1271 kilometers in radius and is composed of iron and nickel, the liquid outer core is 2270 kilometers radius, and the radius of the mantle, the thickest solid layer, is 2885 kilometers.
Remembering that there is an inner core inside the outer core - the radius of the outer core/mantle boundary is about 3,400 km. (the diameter is twice the radius).
The inner core of the Earth is a solid metallic sphere made primarily of iron and nickel with a radius of about 1216 kilometers. It is surrounded by the liquid outer core and the solid mantle.
The answer will vary, depending on which of the two is the height, and which is the diameter of the base. To get the surface area, add up the two circles and the mantle, that is, use the formula: area = 2 x pi x radius2 + 2 x pi x radius x height, or the equivalent (2 x pi x radius)(radius + height).
The inner core is approximately 1271 kilometers in radius and is composed of iron and nickel, the liquid outer core is 2270 kilometers radius, and the radius of the mantle, the thickest solid layer, is 2885 kilometers.
The upper mantle and the lower mantle.
The mantle is divided into the upper mantle and the lower mantle. The upper mantle lies directly beneath the Earth's crust and extends to a depth of about 410 miles. The lower mantle extends from the bottom of the upper mantle to a depth of about 1,800 miles.
the inner mantle is hotter than the outer mantle.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The smallest sphere of the Earth is its inner core, which is a solid ball composed mainly of iron and nickel. It is approximately 1,220 kilometers in radius and is surrounded by the outer core, mantle, and crust.
It is believed to be approximately 758-780 miles (1219 - 1250 km)
Mantle Is The Below Layer Of The Crust In Earth.
