what a slit
When the river begains its upper course,( the starting of a river) it picks up small rocks. In its journey to the lower course (when the river meets the sea) it meets the middle course(the middle stage in the journey to lower course)in which the rocks hit each other and breaks into very tiny sand particles. These sand particles
finally form snd in the river bank (land beside the river) this sand is rich and good for crops and this sand is called silt.
