Question

Give reasons for the following.
1. R.F. has universal application in map making.
2. Distributaries are formed when a river reaches near its mouth.​

Answer 1

Answer:

1)Representative fraction or RF helps to establish a ratio between the two. Thus RF has the universal application of making maps. The scale is in fraction and is independent of any particular unit of measurement. It can be converted into any unit and can be used by any country.

2)The deposition of river's sediment at the mouth of the river in a large amount allows the river to form distrubutaries. A river delta is a landform that forms from the deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.
