GEOGRAPHY: FORM TWO=HUMAN ACTIVITIES

GEOGRAPHY FORM TWO: Topic 1: HUMAN ACTIVITIES

Topic 1: HUMAN ACTIVITIES 
Human activities refers to the sum of all things that human beings do to modify the environment, as well as the exploitation of the environment for the resources needed to survive or to achieve certain goals. Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Therefore human activities are carried out with certain goals or purposes; these purposes can either be:
• Production of food crops.
• Production of cash crops.
• Construction of infrastructure that facilitate movement of goods, services and people; cleaning the area to avoid pollution and outbreak of diseases like cholera, amoebic dysentery, etc.
• Human activities use up resources to produce products and services.

 
Major Types of Human Activities 
Human activities may be classified into four types namely:
 1. Primary activities
2. Secondary activities
3. Tertiary activities
4. Quaternary activities

PRIMARY ACTIVITIES
Primary activities involve exploitation of nature in the production of materials. Production in this kind of activities largely depends on the earth’s natural resources. Examples of primary activities include:
• Farming (Agriculture)
 • Mining and Quarrying
• Fishing
• Forestry (Lumbering)
• Hunting, gathering and livestock keeping

SECONDARY ACTIVITIES
These are human activities that involve a process of manufacturing raw materials into useful products. Secondary activities are of great importance as they lead to fast economic development since they produce products that have immediate demands in the society. They also accelerate development of primary activities by providing a market for raw materials produced through lumbering, agriculture and mining.

TERTIARY ACTIVITIES
These are the activities that involve the provision of services that are needed in the society. Examples of tertiary activities include:
1. Trade (restaurants, hotels, lodges, supermarkets)
2. Schools (Teachers)
3. Hospitals (Doctors)
4. Transportation (Driving) Others include plumbing, mechanics, entertainment, water supply, waste management, advertising, legal services, in court clerical services or religious services.

QUATERNARY ACTIVITIES
These are activities that involve provision of intellectual services and information. These activities were formally included in the tertiary activities. Quaternary activities include high-tech industries with information technology, scientific research, consultancies and library services. Computer based activities like making software are part and parcel of quaternary activities. In general quaternary activities are considered to be new and started in the last decade.

QUINARY ACTIVITIES
These are activities that are done by top executives or officials in fields such as governments. They involve the highest level of planning and decision making in the society or economy. Quaternary and quinary activities e.g. research and information are important in the development of farming, mining, tourism and trade.

Importance of human activities
1. Helps in generation of government revenue
2. Helps in producing raw materials such as cotton for textile industries.
3. They provide employment to peoples in the country..
4. Human activities such as agriculture and fishing lead to production of food.
5. Activities like construction of roads contribute to the development of transport and communication networks. Environmental problems caused by human activities Human activities has great impacts to the environment hence the following is the environmental problems that caused by human activities. These problems include Air pollution, Water pollution, Soil pollution, Deforestation, and Soil erosion.

Measures for controlling environmental problems caused by human activities
1. Discouraged the improper dumping of waste in the soil or water
2. The use of modern methods in agricultural activities such as crop rotation, inter cropping, fallowing strips, contour ridging.
3. Encouraging Afforestation and restricting deforestation 4. Excessive use of chemicals in the control of pests should also be discouraged.
5. The government should Enact strict laws.

NOTES ZA USHAIRI

USHAIRI     NI    NINI ? Shaaban Robert katika uandishi wa ushairi ameandika Tenzi na mashairi ya kimapokeo. Tenzi : Ni aina ya mashairi ya kimapokeo wenye sifa zifuatazo: Kimaudhui ; Ni utungo wenye maudhui yanayosimulia kwa urefu tukio fulani maalum. Waweza kuwa wasifu wa mtu au jambo la kihistoria. Mfano; S. Robert ameandika utenzi wa vita vya Uhuru, ameeleza kuhusu historia. Pia katika Mapenzi Bora, ameeleza kuhusu sifa za mapenzi bora. Utenzi ni utungo wa pili kati tungo za ushairi zenye beti nyingi. Utungo wa kwanza unaoongoza kuwa na beti nyingi kuliko zote katika ushairi ni Tendi. Lakini hapa tutaangazia tenzi zaidi. Utenzi hauna mizani nyingi aghalabu mizani nane, hauna mshororo bali una nusu mshororo/kipande mstari. Vilevile katika utenzi kipande mstari hakigawiki. Pia katika kipande mshororo kuna vipande vinne kwa kila ubeti. Mistari mitatu ya kwanza huwa na vina vyenye urari na kipande mstari cha mwisho/cha nne huwa...

Mpangilio wa sura katika utafiti

MADHARA YA MATUMIZI YA KARATASI ZA OMR KATIKA KUJIBIA MITIHANI. Na LEONARD RENATUS, 0759392855 Tasinifu hii ni kwa Ajili ya Kukamilisha Masharti ya  kukamilisha  Stashahada ya elimu ya msingi Chuo cha Ualimu Marangu. SURA YA KWAZA UTANGULIZI Utafiti huu umekusudia kuchunguza madhara na changamoto zitokanazo na karatasi za OMR  katika kujibia mitihani inayotolewa na baraza la matihani Tanzania (NECTA) . Katika sura hii utafiti huu utaangalia vipengele vifuatavyo:- Utangulizi. Usuli wa tatizo. Tamko la utafiti. Lengo kuu la utafiti. Malengo mahsusi yautafiti. Umuhimu wa utafiti. Mawanda ya utafiti. Tafsiri za istlahi zilizotumika 1.2    USULI WA TATIZO OMR ni kifupi cha maneno ya Optical Mark Reader ni mashine ambayo inatumika kusahihishia karatasi za wanafunzi waliofanya mitihani. Kwa hapa Tanzania karatasi hizi hutumika katika kujibia mitihani ya kumaliza elimu ya msingi kwa darasa la saba . Njia hii ya kusahihishia miti...

MBINU ZA KUFUNDISHIA

Mbinu za kufundishia , ni miongozo mbalimbali atumiayo mwalimu wakati wa kufundisha somo aliloliandaa kwa wanafunzi wake. Walimu wanapaswa kuamua kwa kuchagua kwa makini njia na mbinu bora za kufundishia ili wanafunzi wake waweze kujifunza kwa ufanisi. Ziko njia nyingi za kutengeneza mazingira ya mtoto aweze kujifunza na pia ziko mbinu nyingi za kufundishia. Pamoja na wingi huo tunaweza kuzigawa katika makundi makuu mawili kadri ya jinsi zinavyowashirikisha watoto katika tendo la kujifunza, ambazo tunaweza kuziita shirikishi na zisizo shirikishi . Zifuatazo ni baadhi ya mbinu shirikishi na zisizo shirikishi za kufundishia pamoja na faida na hasara zake:- Njia ya majadiliano , njia hii imekuwa ikitumika katika ufundishaji kwa muda mrefu. Katika kujadiliana mwanafunzi mmoja mmoja hupata nafasi ya mawazo aliyonayo kuhusu suala linalojadiliwa na yeye pia huweza kupata mawazo yaw engine. Katika majadiliano mwanafunzi hupata ujuzi mpya nje na ule aliokuwa nao kabla hajashiriki kat...
