What is the density of earth?

Best Answers

Updated: 24 Dec , 2015 by Jerry Coffey. The density of the Earth is 5.513 g/cm3. This is an average of all of the material on the planet. Water is much less dense than iron, hence an average is needed for ease of use. read more

Earth is the densest planet in the Solar System and the largest of the four terrestrial planets. Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans. read more

Earth is the most dense planet in the Solar System; however, if gravitational compression where factored out, the second most dense planet, Mercury, would be more dense. read more

Since the Earth is a sphere, the formula 4/3πr 3 is used to find the volume. The volume of the Earth is considered to be 1.08 × 10 12 km 3 (or 2.5988 × 10 11 miles 3). I also calculated numbers for the density of the Earth. I knew the mass of the Earth in grams is 5.979 × 10 27. Also, the radius in centimeters is 6.3713 × 10 8. read more
