  1. О чём Олимпиада: International Earth Science Olympiad - это международная Олимпиада по наукам о Земле которая проходит раз в год в одной из стран участниц. Она сильно отличается от IGEO, так как не затрагивает Политику. Для успешного выступления на этой олимпиаде требуются всесторонние знания о природе земли. По большей части данная Олимпиада проверяет насколько хорошо вы знаете Геосферу, Биосферу, Гидросферу, Атмосферу и Астрономию, и то как эти сферы взаимодействуют между собой. Все задания с прошлых IESO здесь: http://www.ieso-info.org/test-from-the-ieso-past-editions/ Официальный Силлабус (список того что нужно знать для победы) здесь: http://www.ieso-info.org/syllabus/ Отбор в Казахстане Казахстанский отбор на межнар проводит организация «Жас Геолог». На их веб-сайте можете найти Контакты и связаться чтобы узнать где и когда пройдёт следующий отбор. Обычно это происходит в конце Осени и в начале Зимы в Астане и Алмате. Нет школьного или регионального тура. Вы в индивидуальном порядке регистрируетесь на республиканский этап. Если занимаете топ 4 то проходите на межнар. Казахстанский этап состоит из двух частей: теория и презентация (возможно в ближайшее время добавят практику). На теории все вопросы на английском, так как сборная Казахстана пишет IESO на английском. Все вопросы также оригинальные, и не собраны из прошлых заданий с IESO (начиная с 2018 года) Презентация тоже на английском на тему Экологических проблем Казахстана (возможно тема изменилась, уточняйте у организации Жас Геолог). Стоит ли участвовать? Да. золотая медалистка IESO из команды США поступила в Стэнфорд, Акназар Кажымурат который выступал от нашей команде и получил серебро, поступил в Гарвард (хотя у обоих скорее всего и так было много достижений). Конкуренция на этой олимпиаде ниже чем например на физике или химии, однако то что вы получаете, а это: диплом с международной олимпиады, бесплатная поездка и друзья со всех концов Света, намного перевешивает то что придётся готовится. Недавно я ездил в Вашингтон D.C. И оказалось, что остановился в том же городе, что и одна из участниц Команды США. Она устроила мне экскурсию по городу, познакомила с друзьями и вообщем мы отлично провели время. IESO может стать вашим билетом в мир тех кто добивается всего. Билетом на американские горки тяжелой но интересной жизни. Вопрос всего один: А хватит ли у вас смелости на ней прокатиться?
  2. Hydrosphere basic information

    1. Hydrosphere is directly linked with geosphere 2. The soil composition in the rate of the seeping of the water influence many factors in the biosphere 3. Atmosphere influences water dispersal and the frequency of precipitation 4. Uncontrolled use of water will cause changes to which biosphere won’t have time to adapt 5. The composition and physiographic structure of the oceans are the product of the reciprocity with the geosphere 6. Original hydrosphere had fresh water only. Evolution of the ocean waters is the result of water’s quality as a universal solvent and minerals quality of solubility. Rivers flow into the oceans dissolving minerals on their way, but when ocean water evaporates to form clouds that will cause rain and go back into rivers, the minerals are not evaporating with them. They remain in the water, which makes the oceans accumulate more and more salt. 7. Tsunami and hurricanes are the result of interactions among the earths systems
  3. Forms of fossilization

    There are 8 common types of fossilization 1. Frozen or dried body. (For example some mammoth are found frozen) soft tissues are preserved) 2.In amber or tar 3.Mold and Cast Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold. The mineralized sediment that fills the mold recreates the shape of the remains. This is called a cast. 4. Preserved bones, teeth, shells 5. Carbonized impressions Carbonization is when living tissue leave a carbon film in sediment and rock. Many plant fossils are preserved through carbonization. 6. Permineralized organisms a process of fossilization in which mineral deposits form internal casts of organisms. Carried by water, these minerals fill the spaces within organic tissue. Because of the nature of the casts, permineralization is particularly useful in studies of the internal structures of organisms, usually of plants. 7. Trace fossils (footprints, coprolites) 8. Chemical fossils (biomarkers) chemicals found in rocks that provide an organic signature for ancient life. *unfortunately no beautiful picture here*

  5. Biosphere in one sentence

    Biosphere is an intersection of all the Earth Spheres. It is the most easily affected Earth sphere
  6. Atmosphere basic information

    The Sun warms the Earth unevenly, which creates global and local flow systems (winds and ocean currents) The composition of the primary atmosphere was the result of volcanic gases. The latter evolution of the atmosphere is intertwined with the evolution of life For hundreds of millions years the atmosphere keeps similar composition due to mutual relations with hydrosphere (oceans), biosphere (photosynthesis & breathing), and geosphere (volcanic dust, erosion) Ocean and air pollution are tightly related. Even minor human related changes in them, can lead to terminal effects in the easily effected Biosphere.
  7. О себе

    Нормально, готовим для вас олимпиаду, скоро Мэск по казахскому, потом САТ сабжект 1 июня, потом ещё пара дэдлайнов. Этим летом похоже отдохнуть не получится.
  8. Chalk quick summary

    Chalk - variety of limestone which is composed mainly of calcite skeletons of plankton (coccoliths) It forms under reasonably deep marine environment Chalk has greater resistance to weathering than clays, therefore when clay layers are washed off, white chalk cliffs are formed, where chalk ridges meet the sea. Due to the similar reason when layers (bands) of chalk reach the surface at an angle escarpments are formed. Chalk absorbs a lot of water, therefore chalk landscapes look so dry Cretacious period is called so, because thick layers of chalk formed during that time. When Alps formed these layers got exposed to the surface in England, Germany and France. Flint (sedimentary rock formed from sponge spicules) and brachiopods, bivalves, crinoids, and sponges be can found in the chalk deposits, as can sharks' teeth. When you see thick chalk deposits you can definitely say that for some time in the past there were very stable conditions for over tens of millions of years. (Like during Cretacious period in Europe) Definitely check out: https://www.geolsoc.org.uk/ks3/gsl/education/resources/rockcycle/page3824.html Other useful links: https://www.nationalgeographic.org/encyclopedia/escarpment/ https://en.m.wikipedia.org/wiki/White_Cliffs_of_Dover
  9. The Galilean moons quick summary

    Galilean moons are the four largest moons of Jupiter—Io, Europa, Ganymede, and Callisto. They are named after lovers of Zeus (Jupiter). Io - the most volcanically active body in the solar system. Io's surface is covered by sulfur. Jupiter's immense gravity causes 100m "tides" on its surface, but instead of water we have ground literally breaking apart. Volcanoes are driven by hot silicate magma. Europa - mostly water ice with hypothetical ocean beneath it. Europa contains twice as much water than Earth does and may contain life too Ganymede - Ganymede is a guy, so Zeus is gay. The largest moon in the solar system and is the only moon known to have its own magnetic field. May have underground oceans too Callisto - extremely heavily cratered and very old. Has a very small degree of current surface activity Io, Europa, and Ganymede have a layered structure (meaning they have a core, mantle, crust, etc.). Layering on Callisto is less well defined (like on our moon, but a little bit better). Heat for keeping Europa's and Ganymede's underground oceans liquid comes from the core and from "tidal" forces too.
  10. Scoria quick summary

    Scoria - Basaltic or Andesitic volcanic rock. It is formed when gases from the lava rapidly escape living these "Frozen bubbles" in the rock. It happens when molten rock is rising in a volcanic pipe, the decreasing pressure allows the gas to expand out (like opening a can of soda releases carbon dioxide). It is very similar to pumice but has a different chemical composition. Old name - cinder Dark colored Mafic with a frothy texture Highly vesicular (>50%) Sinks in water (in contrast to pumice) Composed of glassy fragments and may contain phenocrysts (large crystals compared to the rest of the rock) Volcanic cones of scoria may be left after eruptions of Strombolian type. Very good article about scoria: https://geology.com/rocks/scoria.shtml Other Useful links: https://www.universetoday.com/32247/scoria/ https://en.wikipedia.org/wiki/Scoria
  11. Mercury quick summary

    Mercury - the smallest and innermost planet in the Solar System Orbital period: 88 days Mercurian day: 58 days 15 hours Orbital period/duration of the day = spin-orbit resonance. For Mercury, it is 3/2. When spin-orbit resonance equals to 1, one side of the planet will always be facing the sun, and another side will always be in the dark (like with Earth and Moon). This effect is called tidal locking. Because 3/2 is close to 1 and for some other technical reasons people thought that Mercury rotates synchronically with the Sun. This is not true. On the other hand, 3/2 is indeed close to 1, therefore, Mercury rotates even slower relative to the sun. That means that if you could stand on the surface of Mercury, it would take a staggering 176 Earth days for the Sun to rise, set and rise again to the same place in the sky just once! Temperature range: from -190 (night side) to +430 C (sunny side) Has a big iron core that creates weak Magnetic Field, and contains 83% of the planet's mass & 55% of the volume The orbit is the most eccentrical (circle-like) compared to other planets in the solar system. No atmosphere. It is blown away by the solar wind. No satellites Composition: 70% metallic, 30% silicate Due to its massive core, has the second density in the solar system (5.427 g/cm3). On the first place is the Earth (5.515 g/cm3) Surface shows heavy cratering and mare-like plains (mare is the name for basaltic plains on Moon. It is the sign of ancient volcanic eruptions) Mercury seems to be geologically inactive for already billions of years.

  12. Rock cycle

    (First, look at the image. only then read the article) The Rock Cycle is one of the most important themes in Geology. Rock cycle is similar to the water cycle, but instead of water and ice, we have magma, lava, and rocks. Rock cycle starts with molten rocks below crust called magma. When magma intrudes the crust it cools. If magma cools inside the crust it becomes an intrusive igneous rock (granite, diorite, gabbro). When it cools on the surface it becomes an extrusive igneous rock (basalt, andesite rhyolite) Now, these igneous rocks have two pathways: Burial. There may be lots of reasons why rocks became buried (I will cover them later). The lower you go inside the Earth, the higher temperatures and pressures will be. When you are deep enough, our igneous rocks change and become Metamorphic rocks (gneiss, schist, etc.). Then, when they are buried even deeper, metamorphic rocks start to melt and become magma again. Uplift. Could be caused by an earthquake or something like this. All uplifted rocks are called outcrop. All outcrop undergoes weathering and erosion. Then, weathered and eroded rocks are transported and deposited somewhere. Now, they are called Sediments. When Sediments are buried, under pressure and temperature they become Sedimentary rocks (sandstone, claystone, mudstone, limestone, etc.). Now, sedimentary rocks may be uplifted and become outcrop again or may be buried deeper and become Metamorphic rocks. Metamorphic rocks also have two options: be uplifted and become outcrop, or be buried to become even more dope metamorphic rock. In the end, when buried deep enogh, rocks become magma again.
