When describing the movement of matter in Earth's systems, it is important to consider how the matter moves among the atmosphere, the geosphere, the biosphere, and the hydrosphere. The diagram, for example, shows ways that carbon moves among these spheres.
fossil fuels
and cement production
vegetation
rivers
surface ocean
soils
marine biota
dissolved organic carbon
sediments
deep ocean
rock
Suppose many of the trees in the diagram were cut down and burned or left to decompose.
Explain how the amount of carbon in the atmosphere would most likely change

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25βc)? assume that d for this molecule is 1Γ₯=10β10m. take the total mass of an n2 molecule to be mn2=4.65Γ10β26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
