Answer
Increasing levels of carbon and methane create a warming effect on the planet, which leads to alterations in the water cycle. This can result in higher rates of precipitation and accelerated evaporation, thereby intensifying the interactions between the two cycles.
Step 2
Volcanic eruptions release both carbon dioxide and water vapor

Answer
Such geological events introduce significant amounts of carbon dioxide into the atmosphere, which can influence weather patterns and hence impact precipitation and evaporation rates, affecting the water cycle.

Answer
During photosynthesis, plants absorb carbon dioxide and water, releasing oxygen. This process connects the two cycles, as efficient photosynthesis can regulate both atmospheric carbon levels and water availability.

Answer
The decomposition of organic matter releases carbon dioxide back into the atmosphere while also contributing to soil moisture. Hence, there is a reciprocal relationship, where cycling of nutrients influences both carbon and water dynamics.
