What evidence did scientists use to figure out Earths inner core is solid?
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
How do you know What is inside the Earths 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.
What do you call the layers of earth?
For a science project you could use different colored sand.
What in the earth's interior allows us to use a compass?
The Earth has a magnetic iron core.Actually, it isn't a magnetic 'core'. It is a magnetic deposit that is in the outer 20% of the earths mass. It is like a bubble of cherry juice under the crust of a pie baking. It moves around and slightly changes position over the years, but cycles back to it's prior position on a regular schedule. That is why magnetic north constantly moves back and forth. If you look at the 'magnetic declination', you will see how it changes from year to year. The Magnetic North Pole is actually some distance form the geographic north pole, north of the Hudson Bay. And by the way, the magnetic north pole is actually magnetically the south pole. If you have a magnet that is marked 'N' and 'S', suspend it from a string or place it in a floating saucer. The 'N' will point to the north, being attracted to the SOUTH (opposites attract) magnetic pole of the earth. Somewhere, this got reversed and no one wants to correct it.(response) Allow me to quote from wikipedia: The Earth's magnetic field is mostly caused by electric currents in the liquid outer core. So, although it is the outer core, it is still the core. Not the outer 20% of the Earth's mass. Bear in mind, it is the core that is composed of highly conductive nickel and iron. The layer of magma in the mantle is not electrically conductive, therefore it would not support currents that could generate a magnetic field."mostly caused by electric currents in the liquid outer core" The liquid outer core as defined can be and probably is within the outer 20% of the earth's mass. "Inthe outer 20%" does not mean "is the outer 20%". The specific highly magnetic deposit that defines the earths magnetic field can be and is influenced by electrical current within the core or outer core as you wish. The magnetic deposit may not be totally magnetic on its own. Even as a nail in proximity of a pulsing electric current is not initially magnetic, it will become magnetised by the current, and eventually become magnetic because of the realignment of molecules within it. So yes, the current in the outer core causes or influences but is not the primary source of the earth's magnetic field.
How do you know the Earths structure if man has never been to the 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.
How do you use outer core in a sentence?

What sentence can you use for earth?
The core of the earth has two cores. The inner core and the outer core. Or This is the most delicious apple on the earth, I'm going to give the core to that stray dog.

How do you use urban core in a sentence?
the old city was turned into an urban core because it was old.
Can you use inner core in a sentence?

How do you use closed in a sentence?

What is the best way to describe earth outer core?
the outer core is made if of liquids, while the innor core is made up of iron and other meterials so it is a solid, so in the order of the quiz you are cheating on will most if its in order, crust,mantle,outer core, intercore. i am giving this to you because i do not think you are cheating. please dont prove me wrong, this site is not suposted to promote cheating, and since so many people use it to cheat.
How do you use core in a sentence?
