Outline the relationship between the water cycle and the carbon cycle in the atmosphere. Point marked Allow 1 mark per valid point with extra mark(s) for developed points (d). For example: Note... s for answers Increasing concentrations of carbon (and Methane) in the atmosphere has a warming effect on the planet and leads to increased evaporation (1). This can increase rates of precipitation or equally higher rates of evaporation can further exacerbate aridity (1) (d). Volcanic eruptions release both carbon dioxide and water vapour into the atmosphere (1). Photosynthesis requires both precipitation and carbon dioxide (1). Decomposition releases carbon dioxide and requires the presence of water (1). Some may link this to the melting of permafrost, which is a significant contributor to CO2 release (1) (d). [Show More]
