Sve o Jezerima: Vrste, Nastanak i Najveća na Svetu
1 / 5
Šta su jezera i osnovni pojmovi
Možda si se pitao zašto se voda iz nekih jezera može piti, a iz drugih ne? Jezera su vodene mase u prirodnim udubljenjima na kopnu - za razliku od reka koje se kreću, ova voda miruje.
Ključni pojmovi su zapravo prilično logični. Pritoka je reka koja donosi vodu u jezero, dok je otoka reka koja odvodi vodu iz jezera. Slatkovodna jezera imaju otoku pa se voda obnavlja, dok slana jezera nemaju otoku - voda samo isparava, a soli se nakupljaju.
Postoji i poseban tip koji se zove kriptodepresija - to su jezera čija je površina iznad mora, ali im je dno ispod nivoa mora! Skadarsko i Bajkalsko jezero su takvi primeri. Ovo je važno za testove jer profesori vole da pitaju upravo ovaj pojam.
Zapamti: Kriptodepresija = površina iznad, dno ispod nivoa mora!
Prirodna jezera - tektonska, lednička i vulkanska
Prirodna jezera nastaju bez ikakve pomoći čoveka, kroz različite prirodne procese. Tektonska jezera su prava džinovi - nastaju kada se Zemljina kora pomera i pravi duboke kotline. Bajkalsko jezero u Rusiji je najdublje na svetu upravo iz tog razloga!
Lednička jezera su nastala kada su se ogromni lednici kretali kao buldožeri i izdubili tlo svojom težinom. Kada su se otopili, ostavili su prelepa jezera. Crno jezero na Durmitoru je savršen primer - zato je toliko čista voda na toj visokoj planini.
Vulkanska jezera se kriju u kraterima ugašenih vulkana i obično su mala ali veoma duboka. Zamišljaj ih kao природne bazene u vrhu planine! Krater Lejk u Americi je tako nastao.
Fora za pamćenje: Tektonska su najdublja, lednička su najbistrija, vulkanska su najokruglija!
Prirodna jezera - rečna i kraška
Rečna jezera imaju zabavnu priču nastanka - reka se jednostavno "predomisli" i promeni tok! Staro korito ostane kao jezero u obliku potkovice. Obedska bara kod nas je nastala baš tako. Ova jezera se još zovu i mrtvaje jer su "mrtvi" delovi reke.
Kraška jezera nastaju u predelima gde je mnogo krečnjaka. Voda polako rastvara kamen i pravi udubljenja koja se napune vodom. Zbog toga imaju tu specifičnu plavozelenu boju koja je tako fotogenična! Plitvička jezera u Hrvatskoj su kombinacija - i kraška i lednička istovremeno.
Skadarsko jezero je naš najveći primer kraškog jezera i ujedno najveće jezero na Balkanskom poluostrvu. Plus, to je ona famozna kriptodepresija o kojoj smo učili!
Pametno je znati: Plitvička jezera kombinuju dva načina nastanka - kraški i ledničk!
Veštačka jezera i primeri za poređenje
Ljudi prave veštačka jezera kad im priroda ne da ono što im treba. Jednostavno naprave branu na reci i voila - imaju jezero! Đerdapsko jezero je naše najveće i nastalo je baš tako, kad su napravili branu na Dunavu.
Ova jezera služe za proizvodnju struje u hidroelektranama, navodnjavanje, snabdevanje gradova vodom i turizam. Perućac na Drini i Vlasinsko jezero su još naši primeri.
Da lakše zapamtiš tipove, koristi logiku: tektonska su ogromna i duboka (kao Bajkalsko), lednička su planinska i bistra (Crno jezero), rečna su plitka u obliku potkovice (Obedska bara), a veštačka imaju uvek branu negde blizu.
Najvažnije za testove: Kaspijsko je najveće na svetu, Bajkalsko najdublje, a Skadarsko najveće na Balkanu. Ovo trojstvo skoro uvek dolazi na testovima!
Test trik: Profesori obožavaju da pitaju razliku između rečnih (prirodna) i veštačkih jezera!
Brzi pregled za savršenu ocenu
Evo svega što moraš znati sistemski: jezera su stajaća voda u udubljenjima, za razliku od reka koje teku. Podela po nastanku je ključna za sve testove.
Prirodna jezera: tektonska (pokretanje kore → Bajkalsko), lednička (rad lednika → Crno jezero), vulkanska (krateri → okrugla), rečna (napušteno korito → Obedska bara), kraška (rastvoreni krečnjak → Skadarsko).
Veštačka jezera pravi čovek branama na rekama - Đerdapsko, Perućac, Vlasinsko su naši primeri. Služe za struju, vodu, navodnjavanje i turizam.
Ključne reči za petice: pritoka donosi vodu, otoka odvodi vodu, kriptodepresija ima dno ispod nivoa mora. Slatkovodna jezera imaju otoku, slana nemaju pa se soli nakupljaju.
Zlatno pravilo: Za svaki tip jezera moraš znati najmanje jedan primer iz Srbije ili okruženja!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
