1. What is Density of Earth?

Definition: Density is the mass per unit volume of Earth, typically measured in kilograms per cubic meter (kg/m³).

Average Value: Earth's average density is approximately 5510 kg/m³.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The mass is divided by volume to calculate density. For Earth, this gives about 5510 kg/m³.

3. Importance of Density Calculation

Details: Understanding Earth's density helps in geological studies, gravitational calculations, and planetary science.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is Earth's density important?
A: It helps scientists understand Earth's composition and internal structure.

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: Does density vary within Earth?
A: Yes, density increases toward Earth's core (up to 13000 kg/m³ in the inner core).

Q4: How was Earth's average density first calculated?
A: By combining measurements of Earth's mass (from gravity) and volume (from radius).

Q5: What affects density measurements?
A: Temperature, pressure, and material composition all affect density.
