By using special instruments and using scientific evidences.
The earth has a core because when it was formed the substances split. the dense iron Crystallized out of the melted substances and sunk to the bottom. the density at the core-mantle boundary is really high. the earths core is also what gives it its magnetic field. this is important as its what deflects the harmful solar winds and charged particles.
Scientists use seismic waves from earthquakes to study the interior of the Earth. By measuring how these waves travel through the Earth, scientists have been able to determine that the Earth is composed of different layers with varying compositions, such as the crust, mantle, outer core, and inner core.
Scientists use seismic waves from earthquakes to study the Earth's interior. By analyzing how these waves travel through the layers of the Earth, they can determine the composition and structure of the planet without physically reaching the core.
Scientists study seismic waves and magnetic fields to determine the composition and properties of Earth's core. They use data from earthquakes and magnetic measurements to infer that the inner core is solid iron and nickel, while the outer core is liquid iron-nickel alloy. Deep drilling and experimental simulations also provide insights into the Earth's core composition.
Scientists have studied the Earth's core extensively using seismic waves and magnetic field measurements. The data show that the Earth's core is primarily made of molten iron and nickel, rather than a solid permanent magnet. Additionally, the Earth's magnetic field is generated by the movement of molten metals in the outer core, not by a single large permanent magnet in the core.
Scientists infer that the Earth's core is made of a different material from seismic waves generated by earthquakes. The behavior of these waves as they travel through the Earth's interior suggests that the core is composed of iron and nickel, based on its density and the way the waves travel through it. Additionally, the behavior of magnetic fields around the Earth supports this conclusion.
Scientists believe that the Earth's core is composed mainly of iron and nickel. It is divided into a solid inner core and a liquid outer core. The heat generated by the radioactive decay of elements in the core is responsible for the Earth's magnetic field.
A man named Richard Dixon Oldham discovered that the earth has a core. He determined this by studying the propagation of seismic waves from earthquakes. He hypothesized that the seismic waves had an origin, which he believed came from the center of the earth from a molten core.
the earth's outer core is believed to be a liquid from what scientists infer about it. It is located above the iner core.

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 sizes of Earth's inner core, outer core, and mantle are determined through seismic studies, which analyze how seismic waves travel through the different layers of the Earth. Scientists study the speed of seismic waves and how they bend or refract as they travel through the Earth to determine the size and composition of these layers.
When eartquakes erupt only certaing wavelengths can travel through both liquids and solids, so when the scientists measure to see at what point in the earth the waves refract they can then tell what parts are solid and what parts are liquid
Scientists use seismic waves from earthquakes to study the Earth's interior. By analyzing the way these waves travel through the Earth, they have found that certain waves cannot pass through the inner core, indicating that it is solid. Additionally, laboratory experiments that simulate the high pressure and temperature conditions in the Earth's core support the idea that the inner core is solid.
