Deltas are landforms created by the deposition of sediment carried by rivers as they flow into slower-moving or standing water, such as lakes or oceans. This deposition occurs when the river's velocity decreases, allowing sediments to settle. Deltas can create fertile land and diverse ecosystems, but they can also lead to challenges such as flooding and habitat loss due to changes in water flow and sediment supply. Additionally, human activities like construction and agriculture can further impact delta formation and stability.
