What is the average density of the earth ?

Key Points

• 5.517g cm^-3 is the average density of the Earth.
• Density is calculated by dividing mass by volume.
• The Earth's mass is approximately 5.97 x 10²⁴ kg.
• The Earth's volume is approximately 1.08 x 10¹² km³.
• These values result in an average density of around 5.517g cm^-3.

Additional Information

• The Earth's density varies from the surface to the core.
• The core is composed primarily of iron and nickel, which contributes to the high density.
• The mantle and crust have lower densities compared to the core.
• Understanding Earth's density helps in studying its internal structure and composition.
• Geophysical methods, such as seismology, provide insights into the density distribution within the Earth.
