A glacier. Glaciers are large masses of ice that slowly move downhill, eroding the land and carrying debris like rocks with them.
It is a glacier.
A fast-moving river will cause more erosion compared to a slow-moving river. The higher velocity of the water in fast-moving rivers increases the energy and force exerted on the riverbanks and riverbed, leading to more erosion.
Glacier
The word you want is glacier.
erosion by moving water because Moving water is a powerful force that can shape the land by eroding soil and depositing it in new locations.Rain that falls on the land moves downhill and collects into streams and rivers. Over time, the moving water in the river erodes the soil and carries it away until it a canyon forms.
A slow-moving reptile could be a turtle or a tortoise. Both species move slowly on land due to their anatomy and physiology. They are known for their leisurely pace of movement.
Moving water affects the land in many ways. As a river bends, inertia in the water pushes into the outside bank, eroding it away. As this happens, on the inside bank sand is deposited and starts creating sort of a spit inside the river. Trees and other vegetation thrive along the coast of rivers, known as buffer zones. This stops surrounding land, like urban or farmland, from affecting the river.
My thoughts are: Land is to River as Body is to Artery or veins~ perhaps?
Glaciers. Glaciers are large masses of ice that flow slowly over land, shaping the land through processes like erosion and deposition.
River valleys have very fertile land, a result of rivers moving soil and sediment and depositing it in the valley. It also provides movement for people along the river.
