nucleated
settlement, dispersed settlement
(1c)
1:500 2cm=1km =>26.5cm=xkm 2x=26.5
x=26.5/2 x=13.25km the lenght of river
jamtari is 13.25km

Annual contribution 150.000, 135degree.
Country C, Annual contribution 110.000,
99degree. Country D, Annual contribution
90.000, 81degree. Country A
=50/400*360degree=45degree.
3a)
Sunrise/Sunset. As the earth retaker from
West to East,places in the experiences
daylight (sunrise)first while places in the
west are later exposed to the light of the
sun. If the earth were flat all places in the
earth would experience sunrise(daylight)/
sunset (darkned)at once.
(3aii)
Circumnavigation: circumnavigatioo
means travelling around a circular obect.
Belweer 1519 and 1522 Ferchnand
Magellal and his crew travelled around
the world. Divoing the course of
travel,they rephised they were back at the
begining point. This is a characteristic of
a circular body. If the earth were flat they
would come incontact with an abrupt
edge and fall of.
3b) Town A
(lat5degreeN). Town B (lat10degreeN)
Latitude differenc=5degreeS
10degreeN=150. Distance=Latitude
differenc*Lat1degree.
=15degree*111=1665degreeKM
(4a)
block materials are made of old rocks
which have flat or slightly sloping
surfaces. they have steepn sides.
examples are voges mountains, Hustruck
Mountains
(4b)tourist attraction e.g for
holiday resorts like olumo rocks -sources
of riverse.g River Niger,from the guinea
highlands. -mineral sources- mines are
from highlands e,g tin,columbite,from jos
-relief rain-mountains encourage relief
rain formation
(5a) weathering is the
process by which rocks are disintegrated
into smaller particles by external forces
(5b)chemical weathering is the process
by which rocks are decomposed,
loosened or dissolved by chemical
processes to form residual materials or
smaller particles.
5b)The four process of
chemical weathering. 1)Solution = this
takes place when water e.g rain water
attacks and dissolves rock salts to form a
solution. e.g Rain water dissolvs CaCo3
of limestone leading to the formation of
cracks in rocks. 2) Carbonation.= Co2 in
the air mixes with rain water forming a
weak acid. These acids dissolves rocks
resulting in their breakdown.
3)
Hydrohysis= this is the reaction of water
with rock minerals to produce a rock
entirely different from the initial one
(6a)
Delta is a landform that is formed at
mouth of a river, where the river flows
into an ocean,sea,estuary, e.t.c Type of
Delta - Wave dominated deltas: waves
erosion controls the shape of the delta,
and much of the sediments emanating
from the river mouth is deflected along
the coast line e.g Nile delta -Tide
dominated deltas: erosion is an important
control in tide dominated deltas. e.g
Ganges Deltas.
(6c) -they are formed at
the mouth of the river -they are formed by
erosion of soil sediment -they are formed
by tides of water body
(7a)Flooding is
define as occurrence of execessive
volume of water in area not usually
waterlogged.
(7b) it occurs where there is
poor drainage and where there is heavy
rainfall
(7c) -causes loss of lives and
properties - it causes interuption of socio-
economic activites - it makes human and
vehicular movement difficult -it creates
health harzards via pollution
(7d) -
construction of wider gutters and culerts -
Aviod dumping of refuse in the water
channels -proper channelization of
bloods from city centres -public
enlightment on effect of flooding
