It wasn't too long ago that people thought the earth was flat, that the sun revolved around the earth was flat and the earth was 6000 years old
In the short time of scientific inquiry look how far human knowledge has grown, even though it is still very small
The inner core is our planet's deepest layer. By assessing the types of sound waves that do or do not travel through the core, scientists have worked out that it must be composed of iron and nickel. Not only that, but seismologists are confident that this sphere is slightly larger than Pluto, with a diameter of 2,440 kilometers (1,500 miles).
Scientists in the early 20th century used this magnetic record to prove that the planet’s continents used to be joined together over 200 million years ago before breaking apart.
