The water moves from a river into the air by a process called evaporation. Then carbon dioxide moves from your body into the air by a process called respiration. Finally minerals move from rock into the soil by the process of weathering.
Water moves from a river (hydrosphere) into the air (atmosphere) by a process called evaporation. Carbon dioxide moves from your body (biosphere) into the air (atmosphere) by a process called respiration. Minerals move from rock (geosphere) into the soil (pedosphere) by the process of weathering.
Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber. The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions. The calcium ions diffuse into the muscle fiber.
