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.
What else can I help you with?
How many degrees is the center of the earth?
Its estimated at about 6000 degrees ... about the same as the surface of the sun.
Does gravity increase as you move under the earth?
Yes, but not for quite the reason you might think. If Earth were the same density throughout, gravity would decrease as you moved toward the center, as more and more of Earth's mass would be above you. However, Earth's density is not uniform. Earth's core is made mostly of iron, which is much denser than the rock that makes up the crust and mantle. So gravity would increase as you got closer to the dense. Once you cross into the core, gravity starts to decrease as described above until you reach the very center, where gravity (at least from Earth) is zero.
Are rocks on the moon denser than rocks on earth?
Yes, rocks on the Moon are generally denser than rocks on Earth. This is because the Moon lacks the same geological processes that can alter rock compositions and densities over time, resulting in more uniform-density rocks.
What is the distance between earth and heaven?
In terms of physical measurement, the distance between Earth and heaven is not known as heaven is considered a spiritual or metaphysical realm, not a physical location in space. Different belief systems and cultures have their own interpretations of where or what heaven is.
Are lava and magma the same thing?
Lava is simply magma that has reached the surface.
Would the density of a person be the same on the surface of earth and on the surface on the moon?
yes
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.
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
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.
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.
How many degrees is the center of the earth?
Its estimated at about 6000 degrees ... about the same as the surface of the sun.
Why is it possible for two satellites to circle the earth in orbits with identical period but different heights above the earths surface?
It's possible because the orbital period only depends on the satellite's distance from the center of the Earth, not its height above the Earth's surface. As long as the two satellites have the same distance from the center of the Earth, they will have the same orbital period even if their heights above the Earth's surface are different.
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.
The period of oscillation of a pendulum of constant length at the earths surface is T.its period inside a mine would be?
When you go down below the surface of the Earth, the gravity will initially INCREASE. This is because Earth's density is not uniform - there is more mass concentrated closer to the center, than in the case of a sphere of uniform density. If Earth were a sphere of uniform density, the gravity would get less, once you go below the surface - because some of Earth's material would pull you upward.In any case, if you go further down, eventually the force of gravity will become less. When the gravity increases (as it does initially), the period will become shorter.
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.
If a planet has 4 times the density but half the diameter of earth is it's gravity stronger or less?
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
