Erosion and deposition occur through a multi-step process. Weathering erodes the landscape through various means. Water then carries eroded materials through the path of least resistance, eventually depositing sediments where plants and animals can live in deltas near oceans. Over time, plant growth through photosynthesis releases oxygen into the atmosphere, allowing people and animals to breathe. Upon further review, the author realizes their initial analysis of this process lacked specific details like a sphere-to-sphere impact and location of erosion, leaving unclear the environmental dynamics affecting erosion rates.
