A river delta<span> is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.</span>
The Nile river shifted so the population had to shift as well
Switching a lot of our energy consumption to renewable forms would significantly help the planet because it doesn’t put out pollution or waste, and doesn’t use the resources we are low on like coal or gas. Forms of renewable energy to switch to would be solar energy, wind energy, or hydroelectricity.
