A seismograph is used to sense seismic waves in the earth. The seismic waves are sent down by scientist and how fast and how straight the line is when the seismograph reads them is how they tell which mineral or if its a liquid or solid.
Which is how they know about the inner and outter core, and the mantel.
Scientists discovered that Earth's core has two parts—a solid inner core and a liquid outer core—through the study of seismic waves generated by earthquakes. By analyzing how these waves travel through the Earth, they observed that certain waves could pass through the outer core but were reflected by the inner core, indicating different states of matter. Additionally, the behavior of these waves provided insights into the core's composition and physical properties. This research was pivotal in understanding the Earth's internal structure.
Below the surface of the Earth, you can find various layers, such as the crust, mantle, outer core, and inner core. These layers are made up of different materials and consist of solid, liquid, and molten rock depending on the depth.
Iron is most commonly found in the Earth's core, particularly in the outer and inner core layers. The outer core is primarily composed of liquid iron and nickel, while the inner core is made up of solid iron. Additionally, smaller amounts of iron can also be found in the mantle and crust, but the majority resides in the core.
IDK find it out yourself you cheater I'm kidding it is the crust,inner core,and the lithosphere

They measure how waves from earthquakes travel through the earth, and they test how waves travel through liquid and solid and goo, and they compare the results to find the consistency of the inner core and other layers of the earth.

To be precise, there is actually an outer core and an inner core. You can find the details in the Wikipedia article "Structure of the Earth".
Earth's core is made primarily of iron and nickel.
Scientists find out information on the core by using special tools to dig out samples from deep inside the earth. Special instruments "look inside" parts of the earth we cannot see.
The answer is we know what it is because if you Google it up you will find it says the heatness of the earth's inner core is why.
The most dense layer of the Earth is the inner core, located at the center of the Earth. It is composed primarily of solid iron and nickel, making it the densest part of our planet.
You can find the most Iron and nickel in the earth's inner and outer core.
The four main sections of the Earth are the inner core, outer core, mantle, and crust. The inner core is solid and composed mainly of iron and nickel. The outer core is liquid, while the mantle is a semi-solid layer between the core and crust. The crust is the Earth's outermost layer, where we find continents, oceans, and landforms.
It's approximately (3,963)miles down to the earths core.
