Which 2 elements are found in the inner core and outer core?

Which 2 elements are found in the inner core and outer core?

Core. At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km), according to NASA. It is surrounded by a liquid, outer core composed of a nickel-iron alloy.

What are the two main minerals found in the core?

Earth’s core is mainly iron and nickel with a small amount of a lighter element, perhaps oxygen or sulfur.

What element makes up most of the core?

iron
Nearly 100 percent of the mass of Earth’s core is composed of the two elements iron and nickel.

What are the top 3 elements in the Earths core?

Element
Iron	85.5%
Silicon	6.0%
Nickel	5.20%

What are the two metals found in the outer core and why do they float?

the outer core is primarily made up of iron and nickel. it is mostly a alloy of nickel and iron. . The outer core doesn’t “float”on the inner core since the inner core is solid any more than the oceans “float” on the Earth.

Which two matters are found on the Earth’s 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 are the main mineral constituents of the core?

It is mainly made up of nickel and iron and is called nife (ni – nickel and fe – ferrous i.e. iron). The central core has very high temperature and pressure.

What’s in the Earth’s core?

The inner core is a sphere of solid iron, while the outer core is made of molten iron thousands of kilometres thick. The slow cooling of our planet causes the molten iron in the outer core to flow and swirl fast as heat is transported to the mantle, and this gives Earth its magnetic field.

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.

Which is found in the inner core and outer core?

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 elements are in the outer core? Earth’s outer core is liquid and dominantly composed of iron and nickel (~5–10 wt%).

Which is the most abundant element in the earth’s core?

The core of the earth contains many elements, not just two.However the two most abundant elements in the earth’s core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron.

Are there any precious metals in the earth’s core?

Seismic Shadow Zones. Because these elements are found much more rarely on Earth’s crust, many siderophiles are classified as “ precious metal s.” Siderophile elements include gold, platinum, and cobalt. Another key element in Earth’s core is sulfur—in fact 90% of the sulfur on Earth is found in the core.
