What is the definition of a river system?
A network of rills, gullies, streams, and rivers in an area.
The network of rills gullies streams and rivers in an area is called what?
A river system
What is the different between rills gullies and streams?
a rill makes a gully a gully makes a stream a stream makes a river
How do rills form gulies?
Over time, rills expand and join together causing gullies.
What is the correct order for the process of water eroding soil?
sheet erosion, rills, gullies
What is the correct order of for the process of water eroding soil?
sheet erosion, rills, gullies
What is the difference rill erosion and gully erosion?
A rill is a much smaller channel. A gully was once a rill that got broader and deeper. There are another differences too: 1- Ratio of width to depth: In gully that ratio is approximately 1:1 but in rills width is greater than itsdepth. 2- In agricultural activities, rills can be removed but gullies can not. 3- In specific area, number of rills are higher than gullies. 4- sediment production of gullies is much higher than Rills.
How are rills and gullies formed?
Rills are formed by erosion. As soil erodes a thin channel is left, this channel fills with water. Gullies are formed by running water. An area where many rills have formed can turn into a gully.
What are networks of rills and creeks and streams flow into a river?
floodplain
What statement best describes the process that forms a stream?
Tiny rills enlarge to form gullies, which join to form a stream.
What re the main parts of a river system?
The main parts of a river include a channel, in which the water flows, and a floodplain-a flat region of a valley on either side of the channel. Through the channel and floodplain, water and sediment-material transported by the river, such as sand and silt-are transferred from ridges and mountains to the sea or to a lake. A river starts on hillsides as small channels, or rills. The rills combine to make larger channels or tributaries that eventually come together, forming distinct streams. The largest channels formed by this convergence of tributaries are rivers, and they can carry large quantities of fresh water and sediment across continents.
