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.

Describe in general the structure and interior density pressure and temperature conditions of an average star such as the Sun?
The interior of an average star is modeled after the theoretical pressure, temperature, and density conditions that would be necessary to produce the observed energy and light from the surface. The interior can be described as (1) the core, (2) a radiation zone, and (3) the convection zone. The core is a dense and very hot region where the density fo the core is about 12 times that of solid lead. The radiation zone is less dense and energy in the form of gamma and x rays from the core is absorbed and reemitted by collisions with atoms in this zone. The convection zone begins about seven-tenths of the way to the surface, where the density of the gases is about 1% of the density of water. Gases at the bottom of this zone are heated by radiation from the radiation zone below, expand from heating, and rise to the surface by convection.
Why Earth's interior is warmer than its surface?
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
Would the density of a person be the same on the surface of earth and on the surface on the moon?
yes
What is the surface on Mars?
the surface on jupiter is that it has no surface at all
What information does the color of a star provide?
Its surface temperature
How do fossils provide evidence for moving plates?
Their evidence comes from rocks at earths surface.
How do limestone deposits provide evidence of how plate motions have changed earths surface?
yo but holeLimestone deposits that began as coral reefs provide evidence of how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
Which of jupiters moons surface features provide evidence of a subsurface liquid ocean?
Europa...
What evidence do limestone deposits from coral reefs provide about Earth's history?
Limestone deposits that began as coral reefs provide how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
Geologists obtain indirect evidence about earth's interior by?
Geologists obtain indirect evidence about the earth's interior by reactions to seismic waves. They also use rock samples and drilling samples.
How do you calculate surface density?
How can you calculate surface density if the volume density is 1.4 g/cm3
Will an object sink in water if it has a high density?
It will sink if its density is higher than the water's density, typically 1.0 gm/cm³. Exceptions are very small objects that cannot break the surface tension of water and objects that are shapes such that water is excluded from their interior (ships).

Are there any evidence of volcanic activity on Mercury?
Scientists believe that the interior structure of Mercury includes a metallic core, an intermediate rocky layer, and a thin brittle crust. Surface features indicate that volcanic activity once existed at the surface
The density of the Earth's surface?
a
What is the relationship between density and surface tension?
as we know the relation between surface tension and temperature is inverse, and that of temperature and density also has inverse proportion, then it is clear that the '''surface tension is directly proportion to the density'''.
Why is it that you can still see a clear marble when you drop it into pure tap water?
It has a surface and the interior is a different density to water. It has a different refractive index from water ie it bends light at a different angle.
