The mass of these three is important, as well:


Atmosphere: 8.5 x 10^20 kg
Earth's crust: 1.4 x 10^21 kg (Lithosphere)
Earth's oceans: 1.4 x 10^21 kg


As you can see from these two sets of figures, the oceans dominate, with more than 5 times the heat capacity of the lithosphere, and also of the entire atmosphere.


Something is very wrong with these values. You can see this right away by considering the characteristic thickness and densities of each component. The surface area of the Earth (S_E) is 5.1 X 10^14 m^2. So the mass of each component is approximately: mass= S_E * thickness * density

In particular, the mass of the oceans is about 1000 times that of the atmosphere.



Thickness(km) Density(kg/m^3) Mass(kg) Heat_Capacity (J/(kg-K)) Heat_storage (J/K)
Atmosphere 10 1.2 6.1 X 10^18 1000 6.1 X 10^21
Oceans 10 1000 5.1 X 10^21 4200 (near 0 C) 2.1 X 10^25
Lithosphere 50 2700 6.9 X 10^22 790 (silicates) 5.4 X 10^25
