The natural cycles on Earth are related to each other because they often draw their energy from the same source which is the atmosphere, the oceans, and the Earth's crust . They also draw their energy from the sun as well .
For instance, the carbon cycle is related to the water cycle because water helps in the transportation of carbon to other areas where organisms can use it . It also helps in the weathering of rocks that contain carbon, thereby releasing it .
