You're asking for a breakdown of Earth's composition, including its inner layers. Here's a simplified breakdown:

By mass:

* Iron (Fe): Approximately 32.1%

* Oxygen (O): Approximately 30.1%

* Silicon (Si): Approximately 15.1%

* Magnesium (Mg): Approximately 13.0%

* Sulfur (S): Approximately 2.9%

* Nickel (Ni): Approximately 2.4%

* Calcium (Ca): Approximately 1.5%

* Aluminum (Al): Approximately 1.4%

* Others (Sodium, Potassium, etc.): Approximately 1.5%

By volume:

* Inner Core (solid iron and nickel): About 1.7% of Earth's volume

* Outer Core (liquid iron and nickel): About 1.7% of Earth's volume

* Mantle (mostly silicate minerals): About 84% of Earth's volume

* Crust (thin, outermost layer, mostly igneous and sedimentary rocks): About 0.5% of Earth's volume

Important Notes:

* Inner Earth Composition: We don't have direct samples from the inner core and mantle. Our knowledge is based on indirect measurements and inferences.

* Crust Variation: The crust is not uniform, with oceanic crust being thinner and denser than continental crust.
