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 the two main elements that make up most of the core?
The two main elements that make up most of Earth's core are iron and nickel. These heavy metals are believed to be the primary components that give the core its dense and solid nature.
Which two elements are the most abundant in the earths crust?
Oxygen and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
What elements make up two sections of the core?
The Earth's core consists primarily of two sections: the outer core and the inner core. The outer core is composed mainly of liquid iron and nickel, along with lighter elements such as sulfur and oxygen. In contrast, the inner core is solid and primarily made up of iron and nickel, with some lighter elements potentially present. These elements contribute to the core's temperature, pressure, and dynamic processes, including the generation of the Earth's magnetic field.
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 2 processes heated earths core?
The two main processes that heat Earth's core are radioactive decay of elements such as uranium, thorium, and potassium, and residual heat leftover from the planet's formation 4.5 billion years ago. These processes contribute to the high temperatures at the core, keeping it molten.
What are the two metals that make up the earths core called?
IronNickeland then everything else in much smaller quantities.
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 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.
