Venemaa teaduste akadeemia soovitas võimudel ja tööstusel hakata Popigai kraatrist teemante kaevandama.
Siberis asuv Popigai kraater tekkis suure meteoriidi langemisel Maale 36 miljonit aastat tagasi, edastab RIA Novosti.
Kraatri diameeter on 100 kilomeetrit.
Meteoriidi kukkumisega kaasnesid kuumus ja rõhk. Selle tagajärjel muutusid pinnases olnud grafiidilademed kokkupõrkekohast 13,6 kilomeetri raadiuses teemantideks.
Popigai teemandid on tavaliselt 0,5 – 2-millimeetrise läbimõõduga, mõned suuremad kuni kümnemillimeetrise läbimõõduga.
Süsinik esineb looduses kahe erineva lihtaine - teemandi ja grafiidina.
Venemaa teaduste akadeemia Siberi osakonna andmetel leidub kraatris mitmeid miljardeid karaate niinimetatud kokkupõrketeemante.
Novosibirski geoloogia- ja mineroloogiainstituudi juhi Nikolai Pohilenko sõnul on Popigai kraatris olevad mineraalid väga tugevad ning selle tõttu sobivad tööstuses kasutamiseks.
Teadlaste arvates leidub Siberi kraatris neid mineraale 3000 aastaks..

Below is an extract from a web page. Evaluate whether the page has a high educational
value and could be useful in an educational setting for teaching from primary school to
grade school levels using the additive 5-point scoring system described below. Points are
accumulated based on the satisfaction of each criterion:
- Add 1 point if the extract provides some basic information relevant to educational top-
ics, even if it includes some irrelevant or non-academic content like advertisements and
promotional material.
- Add another point if the extract addresses certain elements pertinent to education but
does not align closely with educational standards. It might mix educational content with
non-educational material, offering a superficial overview of potentially useful topics, or
presenting information in a disorganized manner and incoherent writing style.
- Award a third point if the extract is appropriate for educational use and introduces key
concepts relevant to school curricula. It is coherent though it may not be comprehensive
or could include some extraneous information. It may resemble an introductory section of
a textbook or a basic tutorial that is suitable for learning but has notable limitations like
treating concepts that are too complex for grade school students.
- Grant a fourth point if the extract highly relevant and beneficial for educational purposes
for a level not higher than grade school, exhibiting a clear and consistent writing style. It
could be similar to a chapter from a textbook or a tutorial, offering substantial educational
content, including exercises and solutions, with minimal irrelevant information, and the
concepts aren’t too advanced for grade school students. The content is coherent, focused,
and valuable for structured learning.
- Bestow a fifth point if the extract is outstanding in its educational value, perfectly suited for
teaching either at primary school or grade school. It follows detailed reasoning, the writing
style is easy to follow and offers profound and thorough insights into the subject matter,
devoid of any non-educational or complex content.

The extract provides basic information about the Popigai crater and its diamonds, which is relevant to educational topics like geology and science. However, it lacks coherence, clarity, and depth, making it more suitable as an introductory overview rather than a comprehensive educational resource. The language and concepts are not too complex for grade school students, but the text's focus is more on reporting a discovery than on educational instruction.

Educational score: 3
