Can the earth have the same density in the center as it does on the surface?

No it can not. We know this because we know the mass of the whole Earth (by looking at its gravity) and if the whole Earth were made of rocks of the same density as we see at the surface, there would not be enough mass to account for the gravity. The Earth must have more dense stuff in its core.

How many degrees is the center of the earth?
Its estimated at about 6000 degrees ... about the same as the surface of the sun.
Which is the centre of the earth?
It is "Mecca" ( the holiest place for Muslims), and exactly it's the "Kaaba" in Mecca (Black building in shape of a cube. It located western Saudi Arabia.
What is the distance between earth and heaven?
The same as between the Moon and the Earth. The distance from the clouds to the surface of the Earth is insignificant, compared to the Moon-Earth distance.The same as between the Moon and the Earth.

If Earth's interior was the same composition as the crust what would Earth would most likely do?
Have a lower average density.
Does earth's crust have the same density?
Density will vary from place to place with ocean crust being denser than continental crust.
Would the density of a person be the same on the surface of earth and on the surface on the moon?
yes
Would a smaller planet than earth with the same shape and size have more gravity?
If the planet is smaller, then it can't have the same size. If you assume that a smaller planet has the same density as Earth (and therefore less mass), its surface gravity will be smaller. If you assume that a smaller planet has the same mass as Earth (and therefore more density), its surface gravity will be greater. This is because we would be closer to the planet's center - or to the planet's matter in general.
Is the surface of the earth the same as the centre of the earth?
No. The surface of the Earth is the outermost part, the part where we live. The center of Earth is the core, the middle of the sphere.
How does the density of the earth provide evidence that the interior of the earth is denser that the surface?
The density of the Earth as a whole has been calculated by observing the orbits of the moon and artificial satellites, trajectories of near earth asteroids, etc. We can measure the density of materials from which the surface is composed. The two are not the same. That tells us that the density of the interior is different from the density of surface materials. Since the overall density is greater than the density of the surface materials, the interior must be denser still in order to bring the overall density to what has been observed and calculated.
Is earth's gravity the same on the surface as it is in the center of the earth?
No. At the centre of the earth the acceleration due to gravity is ZERO
How many degrees is the center of the earth?
Its estimated at about 6000 degrees ... about the same as the surface of the sun.
The Moon's average density is about the same as the density of which of the Earth's layers?
The moon's average density is about the same as the density of mantle of the Earth.
Why are not all the layers of earth made from same materials?
gravity separated them by density, iron in the center water and gasses on the outside.
Does the moon have the same density than the earth?
no it is about 1/6 the density of the earth
How is gravity about the same on Mars and Mercury?
This does seem odd. Mars, with a mass that is about twice the mass of Mercury, has about the same surface gravity. Mars' mass is about .107 the mass of earth, and the mass of Mercury is about .055 the mass of earth. The surface gravity on Mars is about .38 times the surface gravity of earth, and the surface gravity of Mercury is about .38 times the surface gravity of earth as well. The difference is that the mean density of Mercury is about 5.43 grams per cubic centimeter, and the mean density of Mars is about 3.93 grams per cubic centimeter. Mercury is quite a bit more dense, so if you stand on Mercury you are much closer to the center of gravity of the planet. Mercury has a tiny slightly bit more gravity than mercury though.
Is the centre of gravity the same for an object placed on the moon and the surface of the earth?
Yes. COG is determined by the object shape & density distribution, not by its location.
In the earth where the gravity of the earth becomes zero?
In a perfectly-shaped sphere, with a smooth surface, and composed of exactly the same substance with the same density throughout it, the force of gravity is zero at the exact center of the sphere. That does NOT mean that 'gravity becomes zero' at the center. It means that at the center, for every speck of mass pulling on you in any direction with any force, there's another speck of mass pulling you in exactly the opposite direction with exactly the same amount of force, so the whole thing adds up to zero. In the real Earth, we can't tell exactly where that point is, because the Earth is not a perfect sphere shape, It doesn't have a smooth surface, and we don't know every last little detail about the distribution of mass inside it.
