When scientists give an answer to a problem, they will test it as many ways as they can and never claim true knowledge, only the fact that a better theory is currently unavailable, this is the basis of the scientific method. About the Earth's inner core- the main way that they have to think about the inner core is by seismic waves. When an earthquake happens in one part of the world, its massive jolt sends a shock wave around the globe. This shock wave has to travel through different materials as it passes. By gauging the speed of the waves and other analyses, they can have a good guess as to what is down there based on the properties of known materials. This is not always foolproof though, as as recently as a couple of months ago, a group of researches found a new property of liquid iron under intense pressure (super-solidified liquid iron) that they didn't know about, something about its magnetic properties. The reason that it is solid is due to the sheer pressure the iron will be under. Gravity is pulling the entire Earth into its centre. That is an incredible amount of weight, and then the rotation which causes massive friction creates a massive amount of heat- ergo solid liquid iron.

Is it true that the earths surface is covered by a continuous layer of soild rock?
s it true that the earths surface is covered by a continuous layer of solid rock?
Facts about the earths core?
The Inner core is the last layer in the earth surface and is what gives the earth its magnetic field. the outer core is liquid nickel and iron but the inner core is 80% solid iron and 20% solid nickel,gold,platinum, and uranium. the inner core is so far in the earth surface we can not reach it we can tell its there by seismic waves.
Is the outer core soild or liquid?
the inner core is a solid. specifically solid nickel/iron alloy. the outer core is a liquid. specifically liquid nickel/iron alloy. both are composed of the same nickel/iron alloy. an alloy very similar to the alloy that makes up metallic meteorites.
Why inner core is solid?
The inner core of the Earth, its innermost hottest part as detected by seismological studies, is a primarily solid ballabout 1,220 km (760 mi) in radius, or about 70% that of the Moon. It is believed to consist of an iron-nickel alloy, and may have a temperature similar to the Sun's surface, approximately 5700 K (5430 °C).

Is the inner core a liquid a solid or a gas?
the inner core is mainly made as a solid. its like the rest besides outer core.
