(a)What is the difference between ice sheets and ice berg?

Ice sheets is a continuous mass of ice covering vast areas of land while an ice bergs is a large block of ice (broken from ice sheets) floating in seas/oceans.

(b)Name three types of glacial moraines.

Laterial moraine
Medial moraine
Terminal moraine
Ground/subglacial moraine
Recessional moraine
Englacial moraine
Push moraine.

The diagram below shows a section of a river. Use it to answer the questions that follow.

(a)Name the features marked S and T.

S - ox-bow lake
T - alluvial deposits

(b)State three conditions that are necessary for the formation of the feature marked S.

Presence of pronounced meanders in the flood plain.
Heavy load being carried by the river.
A reduction in the river gradient/reduction in the river energy to erode vertically/ low velocity.
Presence of obstacles in the river channel.
Laterial erosion on the outer side of the river banks.
Deposition on the inner side of the river banks.
Periodic flooding to cut off neck of pronounced meander.

State five factors that influence mass wasting.

KCSE Geography Paper 1 2013 Section A Question 2.

State five factors that influence mass wasting.

Seismic/earth quake shocks lead to the movement of materials down slope.
Increased overburden/deeply weathered thick/thinnly bedded rock materials are likely to move down slope.
Increase in moisture lubricates the soil.
Lack of vegetation reduces the ability of the soil to hold together.
Under cutting of the slope by excavation/mining/quarrying/construction.
Rearrangement of soil particles by living organism in the soil.
The angle of slope determines the movement of the material.
The nature of the underlying rock.

State five factors that influence mass wasting.

State two characteristics of the weather conditions in the troposphere.

The diagram below represents the structure of the atmosphere. Use it to answer question (a).

(a) Name
(i) the parts marked P and Q.

P - Mesosphere
Q - Thermosphere/Ionosphere

(ii) the layer of discontinuity marked R.

R - Tropopause

(b) State two characteristics of the weather conditions in the troposphere.

Temperatures decrease with an increase in height/normal lapse rate / the rate decrease is 1°C for 160 metres of height l0.65°C per 100 m/6.5 per 1000m
Pressure falls with an increase in height.
The speed of wind increases with an increase in height.
It contains most of the atmospheric water vapour/clouds
