Hydrosphere is made up of water, salt and others so that why i'm giving you this.....(remember water is made up of oxygen and hydrogen,common salt is made up of sodium and chlorine)
Troposphere: nitrogen Lithosphere and hydrosphere: oxygen
The most abundant element in the hydrosphere is oxygen, mainly in the form of water (H2O). This is followed by hydrogen, which is also a key component of water.
Oxygen is the most abundant element in Earth's lithosphere, comprising about 45% of its mass.
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.

The most abundant element in the hydrosphere is oxygen, mainly in the form of water (H2O). This is followed by hydrogen, which is also a key component of water.
The most abundant element found in the hydrosphere is oxygen. It is mainly present in water molecules (H2O) and dissolved oxygen.
Oxygen is the most abundant element in Earth's lithosphere, comprising about 45% of its mass.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
silicon
Aluminum 7.5 to 8.1%
Siliconsilicon at 28%silicon!
That would be silicon, or SiO2
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
silicon.
It makes up the majority of the molten core of the earth.
