Study Notes

Sayniska Deegaanka iyo Maareynta Kheyraadka Dabiiciga

Sayniska deegaanka waa cilmiga isku dhafan ee ku saabsan daraasaadka deegaanka iyo sida aadanuhu u saameeyo. Waxa uu isku daraa mabaadi'da bayoolaji, kiimiko, fiiqsi, juqraafi, iyo cilmiga bulshada. Ujeeddiisa waa in la fahmo deegaanka iyo dhibaatooyinka ay ka jiraan, sida wasakheynta, isticmaalka xad dhaafka ah ee kheyraadka, iyo khasaarada ka dhalata isku dheelitir la'aanta nidaamyada deegaanka.
Dabeecadda Isku-dhafan ee sayniska: Ma ahan cilmiga hal dhinac, waxa uu isku daraa bayoolaji si loo helo fahamka nidaamyada iyo noocyada deegaanka, kiimiko si loo falanqeeyo wasakheynta iyo wareegga kiimikada, fiiqsi si loo fahmo tamarta iyo hawada, iyo maaliyadda si loo fahmo talooyinka deegaanka iyo u qaybinta kheyraadka.
Mawduucyada Sayniska Deegaanka muhiimka ah:
- Kheyraadka dabiiciga ah, sida biyaha, carrada, keymaha, macdanta, iyo tamarta.
- Wasakheynta iyo maareynta qashinka, oo ay ku jirto saameynta hawlaha biniaadanku ku leeyihiin hawada, biyaha, iyo tayada carrada.
- Nidaamyada deegaanka iyo kala duwanaanshaha noolaha, oo ay ku jirto fahamka kala duwanaanshaha noolaha iyo xiriirkooda.
- Isbeddelka cimilada, oo ay ku jirto fahamka kuleylka caalamiga ah, saameynta, iyo talooyinka looga hortagayo.

Kheyraadka dabiiciga ah iyo Maareyntooda

Biyaha: Muhiim u ah nolosha bini'aadamka, beeraha, warshadaha iyo nidaamyada deegaanka, iyadoo ay jiraan caqabado sida abaarta iyo wasakheynta. Xalalka waxaa ka mid ah biyaha roobka, daaweynta, iyo talooyinka loogu talagalay in laga hortago isticmaalka xad dhaafka ah.
Carrada iyo kheyraadka dhulka: Muhiim u ah beeraha, taageeridda nolosha dhirta iyo hawlaha deegaanka, iyadoo ay jiraan caqabadaha sida nabaad guurka, daaqsinka xad-dhaafka ah, iyo dhaqamada beeraha oo aan waara ahayn. Xalka waa beeralay waara, sida wareejinta dalagga, beero dabiici ah, iyo dhaqamada ilaalinta carrada.
Kheyraadka keymaha: Bixiyaan qoryo, oksijiin, iyo deegaanno loogu talagalay noolaha duurjoogta, iyadoo ay jiraan caqabado sida goynta keymaha, oo hadda waxaa loo baahan yahay maareynta keymaha waara, dib-u-beero, iyo ilaalinta kala duwanaanshaha noolaha.
Kheyraadka macdanta: Muhiim u ah warshadaha, soo saaridda tamarta iyo tignoolajiyada. Waxaa jira caqabado sida qadarka macdanta oo dhimaya iyo burburinta deegaanka. Xalka waa dib-u-warshadaynta macdanta, iyo siyaasadaha maareynta waara.

Nidaamyada Deegaanka iyo Kala Duwanaanshaha Noolaha

Nidaamka Deegaanka: Isku dhafka noolaha (dhirta, xayawaanka, iyo miro-cunayaasha) ee la falgala deegaanka jirka (hawada, biyaha, carrada). Waxa uu ku lug leeyahay qaybaha nolosha (biotic), sida wax soosaarayaasha, isticmaalayaasha, iyo burburiyeyaasha, iyo qaybaha aan nolosha aheyn (abiotic), sida biyaha, iftiinka qorraxda, heerkulka, iyo carrada.
Kala Duwanaanshaha Noolaha: Noocyada kala duwan ee nolosha ee dhulka ama nidaam deegaanka, oo ay ku jiraan kala duwanaanshaha noocyada, hiddo-wadaha, iyo nidaamyada deegaanka. Qiimaha kala duwanaanshiyaha noolaha waxaa ka mid ah faaidooyinkan deegaanka, dhaqaale, iyo dhaqan. Isbeddelka deegaanka, isticmaalka xad dhaafka ah, iyo wasakhdu waxay khatar ku yihiin kala duwanaanshaha noolaha.

Wasakheynta iyo Maareynta Qashinka

Wasakheynta hawada: Waxaa ka mid ah qiiqa gawaarida, warshadaha, iyo gubista shidaalka fosil; Saamaynteeda waa xanuunada neefsashada, roobka aashitada, iyo kuleylka. Xalalka waxa ka mid ah isticmaalka ilo tamar cusub, samaynta heerarka qiiqa iyo qalabka xakamaynta wasakheynta.
Wasakheynta biyaha: Waxaa ka mid ah qashinka warshadaha, biyaha musqulaha, iyo daadadkooda beeraha. Nasiib darro, waxay keeni kartaa wasakhda biyaha cabitaanka, dhibaatooyinka bulshada, iyo cudurrada. Xalalka waxaa ka mid ah daaweynta biyaha qashinka iyo dib-u-warshadaynta biyaha.
Wasakheynta dhulka: Waxaa ka mid ah bacriminta, biraha culus, iyo qashinka. Waxa ay keeni kartaa burburka tayada carrada, tayada dhirta, iyo silsiladda cuntada. Xalka waxaa ka mid ah beeraha dabiiciga ah, isticmaalka kiimikooyinka aan waxyeello lahayn, iyo dib-u-soo celinta carrada wasakhaysan.

Isbeddelka Cimilada iyo Kuleylka Caalamiga ah

Isbeddelka cimilada: Isbeddelka muddada dheer ee heerkulka, noocyada roob, iyo isbeddellada kale ee cimilada oo inta badan ay sababayaan hawlaha aadanaha, sida gubista shidaalka fosilka. Soo-saaridda saameynta negative sida kororka heerka bad, iyo dhacdooyinka cimilada daran. Xalalka waxaa ka mid ah yareynta sii daynta gaaska aqalka dhirta lagu koriyo, iyo hagaajinta kaabayaasha.
Kuleylka caalamiga ah: Kororka heerkulka dusha sare ee dhulka, oo sababaya isbeddellada cimilada. Xalalka waxaa ku jirta ka hortagga iyo la qabsashada oo ay ku jiraan yaraynta gaasaska aqalka dhirta lagu koriyo.
