Question

plz any one want to give me answers plz ​

Answer 1

Explanation:

Delta formation at the mouth of river takes place by:

coagulation of positive salt ions and negative river particles because River water contains charged colloidal particles of clay, sand and many other materials. Sea water is very big store house of a variety of electrolytes dissolved in it. As soon as river water comes in contact with sea water coagulate the suspended colloidal particles which ultimately settle down at the point of contact. Thus the level of the river bed rises. As a result, water adopts a different course and delta is formed in due course of time.

Answer 2

Answer:

3.1 (1) Active vertical and lateral erosion in the upper course of the river to provide extensive sediments to be eventually deposited as deltas.

(2) The coast should be preferably tideless

3.2 Temperature and moisture influence the speed of chemical reactions, which in turn help control how fast rocks weather and dead organisms decompose. soils develope faster in warm, moist climates and slowest in cold or arid ones. Rainfall is one of the most important climate factors in soil formation.
