Density is found by dividing the mass by the volume (ρ = m/V). A scientist named Henry Cavendish is known for calculating the mass (and then density) of the Earth. Cavendish assembled an apparatus that consisted of a suspended metal rod with two lead balls hanging from it. He placed masses of metal near these balls in order to measure the force of attraction between them. Correspondingly, he could then find the attraction on a mass the size of the Earth and then determine its density. This famous procedure is known as the Cavendish Experiment. The density of the Earth is higher than that of any other planet in our solar system. Sources vary when it comes to the density of the Earth. All the numbers that were provided are so close to each other, however, that they can each be considered valid. Some assorted numbers given would be: 5.5, 5.52, and 5.15 g/cm3 .
Mean density = 5.515 g/cm3
Average density = 5.52 g/cm3

∙ 9y agoThe Earths crust consists of continental crust and oceanic crust. Continental crust is mostly granitic rock with an average density of 2.7g/cm3, while oceanic crust is made go basaltic rock with a density of 3.3g/cm3.

∙ 13y agoThe average density of Earth is 5540 kg/m3 or 5.54 g/cm3. This is found by dividing the mass of Earth 5.98×1024 kg by its volume 1.08×1021 m3.
The SI standard for density is kg/m3.

What layer of the earth is composed of material of the highest density?
Oceanic crust is more dense than continental crust.
What is denisty and thickness of the first layer on earth?
The density and thickness of the earth crust varies depending on if you are looking at oceanic or continental crust. The oceanic crust's density averages to around 2900 kg/m3 and ranges from 7 to 10 kilometers thick. The continental crust's density averages to around 2700 kg/m3 and ranges 25 to 70 kilometers thick.
If Earth's interior was the same composition as the crust what would happen?
have a lower average density
How can you use the Earth's density to hypothesize that the core of the Earth is composed of very dense matter?
The net density of the earth is much higher than the density of the materials that make up the crust and other portions of the planet that we can reach. There for the parts we cannot yet reach must have a much greater density, or the net density would not be as great as it is.
Why do scientist believe that the earth's crust is metal?
They don't. The Earth's crust is composed mostly of silicate minerals. The core is believed to be metal based on the behavior of seismic waves passing through it. The density of the core is consistent with iron and nickel.
Does earth's crust have the same density?
Density will vary from place to place with ocean crust being denser than continental crust.
The density of Earth's crust is what?
The average density of the Earth's crust is 2.7 grams per cubic centimeter.
What is a Earth crust?
the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)
How did density stratification change the earth?
the earth freezers layers after density stratification which consists of the core, mantle, and crust
Which layer of the Earth has the lowest density?
Of all the solid layers of the earth, the Crust has the least mass. It is the thinest layer, has the lowest density (it floats on the mantle), and in the oceans, it is only about four miles thick.However, the layer with the least mass is not solid, but gaseous. You're breathing it!
When compared to the other layers of Earth which layer has the lowest density?
The Crust
What layer of the earth is composed of material of the highest density?
Oceanic crust is more dense than continental crust.
What is denisty and thickness of the first layer on earth?
The density and thickness of the earth crust varies depending on if you are looking at oceanic or continental crust. The oceanic crust's density averages to around 2900 kg/m3 and ranges from 7 to 10 kilometers thick. The continental crust's density averages to around 2700 kg/m3 and ranges 25 to 70 kilometers thick.
What correctly places the crust in the order of earth's layers?
Differences in density and gravity.
If Earth's interior was the same composition as the crust what would Earth would most likely do?
Have a lower average density.
What can we conclude about the structure of Earth's interior knowing that the average density of Earth is higher than the average density of the rock on the continents and seafloor?
We can conclude that the density of the core and mantle are higher than that of the crust.
What layers of the earth in order increase by density?
mantle crust ocean outer core
