Section A Question 1 Water and carbon cycles Qu Part Marking guidance Total marks 01 1 Outline the relationship between the water cycle and the carbon cycle in the atmosph... ere. Point marked Allow 1 mark per valid point with extra mark(s) for developed points (d). For example: Notes 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). • Some may consider the acid rain as an outcome of the relationship between water and carbon on the atmosphere (1). This may be further linked to ocean acidification (1) (d). The notes for answers are not exhaustive. Credit any valid points. 4 AO1=4 01 2 Analyse the data shown in Figure 1.
