Reading: Abundance of Elements in Earth's Crust

The table shows the abundance of elements in Earth’s crust. Numbers show percentage or parts per million (ppm) in mass; 10,000 ppm = 1%. Note that numbers are estimates, and they will vary depending on source and method of estimation. Order of magnitude of data can roughly be relied upon.
