1. What is Average Density of Earth?

Definition: The average density of Earth is about 5510 kg/m³, calculated using the planet's total mass and volume.

Purpose: Understanding Earth's density helps in geological studies, astrophysics, and planetary science comparisons.

2. How Does the Density Calculation Work?

The calculator uses the formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: Density is calculated by dividing mass by volume. For Earth, this gives approximately 5510 kg/m³.

3. Importance of Density Calculation

Details: Density helps determine composition, compare celestial bodies, and understand planetary formation.

4. Using the Calculator

Tips: Enter mass in kilograms and volume in cubic meters. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is Earth's density higher than surface rocks?
A: The density increases toward Earth's core due to compression and dense metallic composition.

Q2: How does Earth's density compare to other planets?
A: Earth is the densest planet in our solar system due to its metallic core.

Q3: What units are used for density?
A: Standard units are kg/m³, though g/cm³ is also common (1 g/cm³ = 1000 kg/m³).

Q4: Can I calculate density of other objects?
A: Yes, this formula works for any object when you know its mass and volume.

Q5: Why is density important in geology?
A: Density differences drive plate tectonics and reveal subsurface composition.
