29/1/2021

KCSE Geography Paper 1 2017 Section A Question 4.

(a) Distinguish between a river capture and a river rejuvenation.

A river capture is the diversion of the headwaters of one river into the system of an adjacent more powerful river while river rejuvenation is the renewal of the erosive power activities of a river.

(b) Give three ways in which a river transports its load.

Suspension
Saltation
Traction
Solution

(a) Distinguish between a river capture and a river rejuvenation. (b) Give three ways in which a river transports its load.

Name the three types of river erosion.

28/1/2021

KCSE Geography Paper 1 2018 Section B Question 10.

(a) (i) Name the three types of river erosion.

Head ward erosion /spring sapping.
Vertical erosion.
Lateral erosion.

(ii) Describe each of the following processes of river erosion:
I. Abrasion
II. Solution

Abrasion

The river transports the materials downstream.
The materials are used by the river as tools for scouring,
The load is hurled by the water against the banks and dragged along the river bed.
The load chips off the rocks on the bank and river bed.
The load being dragged smoothens the river bed.
The eddy currents rotate the load in the hollows on the river bed grinding the rocks widening into potholes.

. Solution

River water contains both organic and weak inorganic acids.
It reacts with some minerals in some rocks in the river bed to form soluble minerals.
The soluble minerals are carried downstream in solution form.

OR

River water flows over rocks with soluble minerals.
The water dissolves soluble minerals to a solution.
The minerals are carried away in solution.

(c) Describe the characteristics of the upper stage of a river.

The gradient is steep.
The river has a small load.
The flow of the river is fast.
Vertical erosion is dominant.
The cross profile of the valley is v-shaped.
It has interlocking spurs.
The river valley is deep.
The river channel is narrow.
Some parts of the river course have rapids/waterfalls/cataracts.
The river volume is low.
The river channel is winding.

(a) (i) Name the three types of river erosion. (ii) Describe each of the following processes of river erosion: I. Abrasion II. Solution (c) Describe the characteristics of the upper stage of a river. (d) (i) What is river rejuvenation? (ii) Give four causes of river rejuvenation. (iii) Identify three features that result from river rejuvenation.
