Highly reactive and combines well with other minerals.
No. The oxygen in crustal rock is naturally occurring. Oxygen in the atmosphere, however, is due mostly to photosynthesis.
Oxygen is found in large quantities in Earth's crust. Oxygen makes up about 46% of the Earth's crust by weight and is the most abundant element in the Earth's crust.
Oxygen is the most common element in the crust.
Next to oxygen, silicon in the form of silicate minerals is the most abundant element in the rocks of the crust. As these rocks are weathered and eroded, the silicon becomes part of sedimentary rock.
Oxygen is the most common element in the crust.
Oxygen.
Oxygen
the majority of it is found in water
No because iron reacts with various substances including oxygen in the air to produce rust.
the majority of oxygen is found in water therefore you cannot breathe the oxygen in water
Oxygen is most abundant in rock, as an elemental component of minerals.
The oxygen in the Earth's crust is not 'free' as it is in the atmosphere. The oxygen in the atmosphere is mainly in the form of the molecule O2, which is a gas. However, in the crust the oxygen is either bonded to elements to form various compounds, trapped in enclosed places, or dissolved in other solutions. Hope it helps :)
