The density of the Earth can be estimated by observing the time that seismic waves take to travel through it. Waves travel faster through denser objects leading to the conclusions that the Earth is density stratified with the most dense material at the center. The change in velocity of the seismic waves gives an estimate of the density of the material that it is traveling through. Knowing the depth of these composition changes allows us to calculate the volume of each particular compositional "shell" and a weighted average of these will give an estimate of the Earth's density.
What else can I help you with?
What is the name of the temperature scale used to measure earths heat?
The temperature scale used to measure Earth's heat is called the Celsius scale.
What do we call a measure of height above earths surface?
Height above earths surface is called elevation
Does the density of the earths atmosphere increase with altitude or decrease?
The density of Earth's atmosphere decreases with altitude. As you move higher up in the atmosphere, there are fewer molecules of gases present, leading to lower density.
Is the altitude a measure of height above earths surface?
Yes, altitude is a measure of height above Earth's surface, typically measured in feet or meters. It can be used to indicate how high an object is located in relation to sea level or ground level.
A measure of how tightly matter is packed?
Density is a measure of how tightly matter is packed. It is calculated by dividing the mass of an object by its volume. The higher the density, the more mass is packed into a given volume.
How is Mercury's average dens ity is high as earths?
How is Mercury's density is about high as the earths density
What instrument is used to measure density how i measure density of acid in battery?
It is called a hydrometer.Also, density equals mass divided by volume.See the Related Questions to the left for more information about hydrometer and density.yup
What pieces of laboratory equipment do you use to measure density?
To measure density in a laboratory setting, you commonly use a balance to measure mass and a graduated cylinder to measure volume. By dividing the mass of the substance by its volume, you can calculate the density.
How can graphing be helped used to help measure density?
Graphing is used in measuring density. It plots the temperature and density as read, and gives the true density at standard conditions.
What are the standard units used to measure the optical density at 600 nm in a spectrophotometer?
The standard unit used to measure optical density at 600 nm in a spectrophotometer is absorbance (AU).
Why is the hydrometer used to find density?
A hydrometer can be used to find the specific gravity (relative density) of a liquid by determining how much water it will displace. Various calibrations are used for different kinds of liquids.
What is the tool used to find the density of a liquid?
Hydrometer is used in batteries to measure density. A float tells you the density using displacement.
A graduated cylinder is used to measure?
density -------- Graduated cyllinders are used to measure volumes of liquids, powders or fine granules.
What is the name of the temperature scale used to measure earths heat?
The temperature scale used to measure Earth's heat is called the Celsius scale.
How was the Hygrometer used?
hygrometer used to measure density of relative humidity in air by using a sensory element such as a hair
What unit is used to measure distance outside Earths solar system?
Light years
