Seismic wave detection from the boundary between the inner and outer core indicated that the inner core may be solid. Studies of the Earth's magnetic field also indicates properties of the inner core that help form the magnetosphere which protects the planet from solar radiation. There is also evidence provided by the study of the composition of meteorites which were derived from planetary collisions. Much is still unknown, of course.
What else can I help you with?
Why do scientists believe the Inner core is solid?
Scientists believe the inner core is solid because of its seismic properties. S-waves cannot travel through liquid, yet they can travel through the outer core but are noticeably dampened in the inner core, suggesting it is solid. Additionally, studies on iron under high pressure and temperature conditions support the idea of a solid inner core.
How do you know how big the inner core outer core and mantle are?
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.
How do scientist find out stuff about the inner core of the earth?
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.
What do scientists believe about the earth's core?
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.
How do scientists know that the inner core is solid?
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.
What leads scientists to believe that earth's inner core is a solid?
Scientists believe Earth's inner core is solid because of seismic waves from earthquakes that travel through the core, the behavior of seismic waves, and the way in which they are reflected or refracted. This information suggests that the inner core behaves more like a solid than a liquid. Additionally, studies of the Earth's magnetic field and the behavior of seismic shear waves also support the idea of a solid inner core.
How has the inner core affected mankind?
No, at least not yet or not found to be. Scientists have not seen any possibilities for the inner core to affect mankind.
What lead scientists to believe that Earth's inner core is solid?
Waves traveling through the inner core go faster than those through the outer core.
What do most scientists think the earth's inner core is madde of?
iron

What did scientists use to figure out that earth's inner core is solid rock?
Seismic waves travel faster when they travel through the core
Which layer of Earth do scientists believe is most likely made of solid metals?
The inner core.
What is the piece of evidence used to determine the phase of the core?
The primary piece of evidence used to determine the phase of the Earth's core is seismic waves. By studying how seismic waves pass through the core, scientists can infer information about its composition, temperature, and state (solid inner core, liquid outer core).
