The quantity left to increase CO2 levels in the atmosphere if plants have taken 10 Gt of carbon, and some is dissolved in the oceans.

Explanation of Solution
Introduction:
Fossil fuel is formed by anaerobic decomposition of buried dead organisms containing energy that originates from photosynthesis by natural process.
Increasing CO2 is stored in the atmosphere that leads to an increase in global warming. This condition increases the number of water vapors in the atmosphere. If the 10 Gt of carbon is taken by the plants and some dissolved in ocean, then 800 Gt of carbon is left in the atmosphere. This is because human carbon emissions to the atmosphere are not in balance with the uptake of carbon on land and some parts dissolved in the ocean.

For example, the thickness and dip of a planar layer should remain relatively constant unless the map data requires otherwise. Planar layers should also be laterally continuous unless there is evidence otherwise. Similarly, keep the structure as simple as you can. Steps to producing a cross section: I. Choose the location and direction of the profile on the geological map (usually a straight line) II. Draw or plot the topography of the profile on the cross-section III.
