What two elements make up earths 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. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
What two elements make up more than 80 percent of the atoms found in the earths crust?
oxygen and silicon are the two elements that make up more than 80 percent of the atoms found in the Earths crust...(there is a constructed response for you guys)
Does the core of the earth makes up two thirds of the earths mass?
no
What are two divisiosn of the earths core?
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
What are the main elements in the outer core?
The outer core is a layer of the Earth, the second to last layer. It creates the Earths Magnetic field by moving around the inner core. There are two metals that make up the outer core, these two metals are iron and nickel. The inner core is so hot that it melts the nickel and iron turning it into liquid magma.
What are two facts about earths core?
1.The Earth's core is composed of heavy elements, such as iron, nickel, and the other heavy elements. 2. Due to gravitational compression, and the presence of radioactivity, the core is very hot (perhaps 6 000oC) and very dense. The inner core is solid due to gravitational pressure. The outer core is liquid or at least plastic.
Is the earths core made of hard rock?
No. The Earth's core is divided into two parts: a solid inner core and a liquid outer core, moth made mostly of iron.
What are the two most abundant element in the earths core?
Although we can not see them, we know from certain meteorites (Nickel/Iron meteorites) and from the density measurements of the rocks we see at the Earth's surface compared to the mass of the whole planet that the two most abundant elements in the Earth's core must be Iron and Nickel. Iron being the predominant of the two.
What metals makes up the core?
The outer core is a layer of the Earth, the second to last layer. It creates the Earths Magnetic field by moving around the inner core. There are two metals that make up the outer core, these two metals are iron and nickel. The inner core is so hot that it melts the nickel and iron turning it into liquid magma.
The two rows of elements placed at the bottom of the periodic table represent what elements?
they are the lanthanide and actinide series of rare earths
What two elements make up the majority of earths sand?
Without modifiers, the word "sand" refers to a substance that is almost entirely silicon dioxide.
The earths core is made of?
The Inner (solid) and Outter (liquid) Core are made up of Nickel and Iron.
