How can carbon move from "land" to bodies of water? describe the way human impact has lead to increased levels of co2 in the atmosphere.

It begins with carbon moving from land to the atmosphere. Through combustion, carbon turns to gaseous carbon dioxide. When the atmosphere interacts with the hydrosphere, some of the carbon dioxides dissolves in the water as dissolved carbon dioxide. This can also happen through precipitation. Some of the dissolved carbon dioxides can react with water  into carbonic acid.

One way is through the burning of fossil fuels. One of the products of the burning of hydrocarbons is carbon dioxide.  Another is clearing of forests. Forests are major carbon sinks since trees sequester carbon dioxide from the atmosphere.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
