The inner and outer core consist primarily of the elements nickel and iron.
This is a highly debated topic, though most geophysicists would say the the inner core is mostly Nickel, Iron, and a tiny bit of Sulfur.
The Earth's inner core is made of solid iron and nickel, like the outer core, though the outer core has MOLTEN iron and nickel for its contents.
The inner core of the Earth is composed of solid iron. The outer core is made up of molten metals, primarily a nickel-iron alloy.
This is called the outer core.
It is composed of an iron and nickel alloy, and is called the inner core.
The outer core of the Earth.
An alloy of solid nickel and iron, mostly.
The core of the Earth is defined by two layers: the inner core which is solid, and the outer core which is liquid. Both are composed primarily of iron with nickel.
The inner core is the only portion of the Earth which is considered to be composed of solid iron with nickel. The outer core surrounding it is a liquid iron-nickel alloy.Inner core
Iron, nickel, and small amounts of lighter elements.
The core of the Earth is defined by two layers: the inner core which is solid, and the outer core which is liquid. Both are composed primarily of iron with nickel.
The inner and outer core consist primarily of the elements nickel and iron.
The inner core of the Earth is composed mainly of a nickel-iron alloy. There's a liquid outer core that is made of iron and is very dense. The inner core is made of solid iron and nickel.
The layer that surrounds the center of the Earth is called the core. It is divided into the inner core and outer core, with the inner core being solid and made mostly of iron and nickel, while the outer core is a liquid layer also composed of iron and nickel.
Every inner planet has a core. The cores of Mercury, Venus, and Earth are composed of iron-nickel. Mars's core is made of liquid iron sulfide mixed with some nickel.
This is a highly debated topic, though most geophysicists would say the the inner core is mostly Nickel, Iron, and a tiny bit of Sulfur.
