Most of Earth's volume is contained in the mantle, which is the layer between the crust and the core. The mantle makes up about 84% of Earth's volume and is composed of solid rock that can flow slowly over long periods of time.
The mantle is the layer of the Earth that occupies the most volume, accounting for about 84% of the Earth's total volume. It is located between the core and the crust and is mainly composed of silicate rocks.
The layer of the Earth that contains most of the Earth's volume is the mantle. It is located between the Earth's crust and the core and is composed of hot, semi-solid rock.
Oxygen is the most abundant element in Earth's crust.
The two Earth regions where oxygen is the second most abundant element by volume are the Earth's crust, after silicon, and the Earth's atmosphere, after nitrogen.
Nitrogen is the most abundant gas in Earth's atmosphere at approximately 78% by volume.
Oxygen is the second most abundant element by volume in both the Earth's crust (after silicon) and in the Earth's atmosphere (after nitrogen).
