Hydrology is the study of water and how it moves through the environment. π§
Tributaries are vital in the hydrological cycle. A tributary collects rainwater, snowmelt, and groundwater, helping to keep rivers flowing. Water flows downhill thanks to gravity, so tributaries travel from higher places, like mountains, to lower areas, like valleys. π
Sometimes, tributaries can dry up due to hot weather or human activities, but they can also refill during rainy seasons, helping nature maintain a balance. β
