What 2 elements are found in the outer core?
The outer core is about 1,400 miles thick, and it’s made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form.
What is the main element of the outer core?
The outer core, about 2,200 kilometers (1,367 miles) thick, is mostly composed of liquid iron and nickel. The NiFe alloy of the outer core is very hot, between 4,500° and 5,500° Celsius (8,132° and 9,932° Fahrenheit).
What is the most common element in the outer core?
Iron
Iron is the most abundant element, by mass, in the Earth, constituting about 80% of the inner and outer cores of Earth. The molten outer core is about 8000 km in diameter, and the solid inner core is about 2400 km in diameter. Iron is the fourth most abundant element in Earth’s crust.
What are the 2 elements that make up earth’s core?
What are the 2 elements that make up Earth’s core? The Earth ‘s core is mainly made of iron and nickel. The solid inner core is made of mainly iron crystals with small amounts of nickel and heavier elements such as gold and platinum. The liquid outer core is a nickel iron alloy with small amounts of heavier elements.
What kind of material is the inner core made of?
The solid inner core is made of mainly iron crystals with small amounts of nickel and heavier elements such as gold and platinum.
What makes up the outer crust of the Earth?
But the outer core is something special. You might find the outer crust is made form a variety of elements including silicon and oxygen. But the outer core is primarily made from iron and nickel.
Which is the most common metal in the Solar System?
The most common metallic elements that remain uncombined, at least in our Solar System, are iron followed by nickel. Like rocks, metals may be liquid deep inside the hot interiors of large bodies, as we see in the structure of Earth.
