SS3 Second Term Geography Lesson Note 

 

Below are the 2022 complete SS3 Second Term Geography Lesson Note 

Week 1

Topic: World population

Content:

1. Definition
2. Concepts of population
3. Factors affecting the growth population

Definition of Population

Population is defined as the total number of people living in an area at a particular time.

Population Concepts
(a) Over Population: is defined as a situation whereby the population is considered too large for the availability resources. Over population refers to a situation where the population exceeds the available resources of the country

(b) Under Population is the type of population that is less than the available resources of a country. It then means that, the size of population is too small that when combined with the available resources of a country and given the level of existing technology it will secure minimum returns per head.

 Week 2

Topic: World Population (II) For previous lesson; see: https://passnownow.com/namaste-lesson/world-population/

Content:

1. Pattern of world population
2. Problems of rapid growth population growth
3. Advantages and Disadvantages of low and high densities

Pattern of world population distribution is distributed into three; Which are:

(a) The very densely populated parts of the world: the most densely populated areas of the world include
(i) Industrial North – West Europe: this include countries like Great Britain, Franze, German, Denmark, Belgium. These areas are highly industrialized due to the presence of coal and iron

(ii)  Industrial North – Eastern U.S.A: this is the great industrial belt of the United States and Canada stretching from the shore of the Great lakes though Pittsburg to New York which is very rich in Coal and iron. To learn more, Click here.

Week 3

Topic: Settlement

Meaning of Settlement

Settlement is a collection of buildings with people living in them. It is centre of human activities and it consists of houses, communication network, roads, tracks, railways etc. It could be one house, a village, a town or a city.

Favourable conditions for siting a settlement

1. There must be adequate and dependable water supply for man use
2. The soil must be fertile to produce agricultural activities
3. Such lands must be lowland and well drained for easy erection of buildings. To learn more, Click here.

Week 4

Topic: Environmental Interaction

Definition of Environment and Environmental Interaction

Environment is defined as the total surrounding or medium of any organism in a given area. This include physical surroundings, climatic factors and other living organisms in the surroundings.

Human Environmental Interactions can be defined as interactions between the human social system and (the “rest” of) the ecosystem.

Spheres of the environment

The environment, which is the earth, is grouped into four sphere and these are

• Lithosphere: This is the solid portion of the environment which contain rocks, sand, soil minerals etc
• Hydrosphere: This is the liquid part of the environment like rivers, lakes and oceans
• Atmosphere: This is the gaseous portion of the environment where gases like oxygen, nitrogen, carbon dioxide etc are found
• Biosphere: This is the portion of the environment where plants and animals are found. To learn more, Click here.

Week 5

Topic: Environmental interventions II

Definition of Environmental Intervention

Environmental Intervention refers to the forces of nature and the activities of man that change the natural existence of the components of ecosystem

Types of environmental intervention

There are two types of environmental interventions in our environment. These are natural and human interventions

(a)          Natural intervention; It is caused by a number of natural process which include:

(i) Desert encroachment              (ii) Vulcanism

(iii) Sea level changes                     (iv) Earthquakes

(v) Tectonic movement                 (vi) Climatic changes

(vii) Drought                                       (viii) Hurricane                   (ix) Flooding. To learn more, Click here.

Week 6

Topic: World Trade

Definition of Trade

Trade refers to buying and selling or exchange of goods and services between one region and another in the same country or between one country and another

Division of international trade

(a) Import trade involves the buying of goods and services from another country into your own country

(b) Export trade involve the selling of goods and services produced in one’s country to another country

Importance of international trade

1. International cooperation is fostered between two nations which are involved in international trade
2. New products that would otherwise have been unavailable in a country are provide
3. Jobs are provided through activities involved in the exportation from the sales or export of their goods to another country
4. Export goods or products are easily stimulated through increased production in the source region. To learn more, Click here.

week 7

Topic: Map work

Contour representation of land form

The following are some common landforms or relief features that can be represented on map by using contour lines.

1. Valleys: They are lowland between two highlands. Valleys are represented by V- shaped contour lines with the apex of the V- shape pointing towards the highland. When a valley contains water, it is called a river valley but when it contains no water, it is called a dry valley
2. Spurs: They are projection of highlands into low ground. That is the V-shape points to the lowland spurs separate one valley from another and the contour numbering decreases outward.
3. Conical Hill: They are usually circular in shape and become smaller and smaller towards the centre
4. Round top: This hill are contours showing round top hills that are circular but do not taper to a points. The inner most circle of contour is fairly large
5. Isolated Hill: This is a hill which stands apart or is far removed from other hills or highlands. It may either be round or conical in shape. To learn more, Click here.

Week 8

Topic: Interpretation of topographical maps

Important features that need interpretation include relief, drainage, settlement, communication and land use relief

Procedures for interpreting relief

• Use contour lines, spot heights or trigonometrical station to note the highest point and the lowest point on the land. The highest point is found on the highest contour lines while the lowest point i found on the lowland
• Note the preparation of the land occupied by highlands and low lands
• Note the specific land form and relief whether a ridge, hill, plateau, knoll, plain
• Note the location or direction of these relief features like plateau, hill, ridge, etc on map
• Note the heights of the lowlands above the sea level and whether they are flat or plains of undulating
• Note if the hills and plateaux are dissected or not. To learn more, Click here.
