a Delta
The source of a stream is called a headwater or headstream. This is where the stream initially begins, often from a spring or melting snow.
When rain runoff travels over the surface of the land and enters a stream, it is called surface runoff. This water can carry pollutants and sediment into the stream, affecting water quality and aquatic ecosystems.
Ravine: A deep, narrow gorge with steep sides formed by erosion from a stream or river.
Eskers are formed when a subglacial stream of meltwater flows within, on, or beneath glaciers. As the glacier melts and retreats, sediment and gravel carried by the stream are deposited in long winding ridges. These deposits form the characteristic winding shape of eskers.
Lightning is formed when electrical charges build up in clouds and on the ground. When the difference in charges becomes strong enough, a channel of charged particles called a stepped leader forms from the cloud towards the ground. This channel is then met by a stream of charged particles called a return stroke, which creates the visible lightning bolt that we see.
A Misfit Stream is formed when water melted from the mountains flow into a U-shaped valley. Then because the stream is too small for the valley it is then called a misfit valley.
The water (stream, river) would become heavily silted and deposit the silt at the river mouth, forming sandbars and hampering shipping. Such silt could also hamper wildlife and even drive away fish that only like clear running water.
River valleys are formed by stream erosion.
The area where a freshwater river or stream enters the ocean is called an estuary. It is a coastal area of brackish water formed when freshwater enters the ocean.
A stream or river called that flows into a larger stream or river is called a tributary.
That would be called an oxbow lake.
I suppose you think of a laser. Depending on the energy put into it, it can be used as a markerpen or even be used to cut through steel up to 2 cm thickness.
A stream valley is usually 'V' shaped, formed by erosion from a stream. A glacial valley is usually 'U' shaped, formed by the action of a glacier.
Option c is correct
1st order stream is a stream that formed Bc OF Spring and any water. and represent the first steam of the watershed
A small stream is called a creek.
The side of a stream is usually called its bank.
