GEOGRAPHY PRACTICAL


(1b)
Length of the map = 19.2
Length of the land = 19.2
19.2*50,000/1000
=960km

-human Features-
(i)School
(ii)Hospital
(i)Market

-Physical features-
(i)River
(ii)Contour
(iii)Tree

==================

(choose Any Two)
(i)Weather is the atmospheric condition of a place over a short period (days, weeks, hours, months) WHILE Climate is the average condition of a place over a long period of time(35years)
(ii)Weather changes very often WHILE climate does not change very often
(iii)Weather describe atmospheric condition of a small area WHILE climate describe the atmospheric condition of a large area

(5bi)
Sunshine = Sunshine is measured by sunshine recorder or light meter
(5bii)
Rainfall = Rainfall is measured by an instrument called Raingauge
(5biii)
Cloud cover = The amount of cloud in the atmosphere is measured by Oktas. In order words,the amount of the cloud in the air is expressed in okras or Eights of the sky cover

(5c)
The speed of that wind can be measured using a tool called an anemometer.
An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed. When wind pushes into the cups, they rotate the axis.

Reading is taken twice daily eg 9.00hours and 15.00hours
It is recorded in note book. it states the date of recording .The record is signed by the observer

Weathering is the process where rock is dissolved, worn
away or broken down into smaller and smaller pieces.

(4b)
(i)surface area,
(ii)rock composition
(iii)Climatic conditions

(4c)
Exfoliation is a process involving the weathering of rocks. A
sudden change in temperature may cause cracks and fissures
in the rocks. As water percolates into these fissures, chemical
weathering takes place. The sudden expansion and contraction of rocks results in the peeling off of the outer layers of the rocks.
=====================================

(3a)
(i)Latitude
(ii)Altitude
(iii)Continentality or distance from the sea
(iv)ocean currents
(v)planetary winds and pressure belts

(3b)
(i)It has constant high temperature with daily temperature of 26°C with no winter
(ii)It has annual rainfall of over 200cm and rainfall is throughout the year
(iii)It has high humidity all year round with double maxima of rainfall
(iv)It has small annual temperature range of 2°C – 3°C
(v)It has convectional rainfall accompanied by lightening and thunder.
=====================================

(8a)
Atmospheric pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.

(8b)
(i)Mobile source
(ii)Area sources
(iii)Natural sources
(iv)Stationary sources

(8c)
(i)Deterioration of fields
(ii)Acid rain and Smog effect
(iii)Respiratory health problems
(iv)Climate change

VERIFIED GEOGRAPHY ANSWER

(1a)
(i) Climatic Conditions: Climatic or soil conditions in certain areas are suited for the production of a particular
product.

(ii) Nearness to Raw Materials: Nearness to raw materials is a dominant factor in the location of an industry, especially that industry which uses bulky raw material that is expensive to transport and looses weight in the manufacturing process.

(iii) Nearness to Sources of power: Nearness to the sources of power is another important cause of localisation of industries.

(iv) Nearness to Markets: Before starting an industry, an entrepreneur has to take into consideration the market potentialities of his product.

(v) Adequate and Trained Labour: Industries tend to be concentrated in those areas where adequate supplies of trained labour are available.

(1b)
(i)Reputation: The place where an industry is localised gains reputation, and so do the products manufactured
there. As a result, products bearing the name of that place find wide markets, such as Sheffield cutlery,

(ii)Skilled Labour: Localisation leads to
specialisation in particular trades. As a result, workers skilled in those trades are attracted to that place.

(iii)Growth of Facilities: Concentration of an industry in particular locality leads to the growth of certain facilities there. To cater to the needs of the industry, banks and financial institutions open their branches, whereby the firms are able to get timely credit facilities.

(iv)Subsidiary Industries: Where industries are localised, subsidiary industries grow up to supply machines, tools, implements and other materials, and to utilise their by-products.

(v)Employment Opportunities: As a corollary to the above, with the localisation of an industry in a particular locality and the establishment of subsidiary industries, employment opportunities considerably increase in that locality.

(2a)
(i)houses are close together.
(ii)Social services are available in these settlements.
(iii)Roads are narrow in the old parts of these settlements.
(iv)People from different castes, religions,races and ideologies live together in these settlements and hence they have a better social life.

(2b)
(i)Selling expensive or rare goods/services e.g. Lagos.
(ii)Providing jobs in industry or services.
(iii)As an administration centre for the area around it.
(iv)As an entertainment centre, for example offering sporting attractions, shopping areas, restaurants.

(2c)
(i)Body of water (transportation routes, water for drinking and farming)
(ii)Flat land (easy to build)
(iii)Fertile soil (for crops)
(iv)Forests (timber and housing)


(4)


(5)


(5b)
(i) Professional development reimbursement.
(ii) Performance & career development programs.
(iii) Frequent company social activities & opportunities to give back to the community.

(5c)
(i) import/export processes.
(ii) heavy human and vehicular congestion around the ports.
(iii) difficulty in gaining access to the ports due to bad roads.
====================================


(6ai)
(i)Sun
(ii)Fossil fuel

(6aii)
(i)Solar energy
(ii)Wind energy

(6b)
(i)Bad governance
(ii)Lack of technological equipments
(iii)Low funds
(iv)political Division

(6c)
(i)Good governance should be installed.

(ii)Nigeria Energy companies should be provided with Modern age technological gadgets.

(iii)Funds should be they first thing to be pumped to develop a project like this. You need funds and skilled engineers.

(iv)Politics should taken away from this aspect, because its what’s killing they system when Nigeria is too political about thermal energy building it brings they country down to its side.
