(Bild Hohl)</p></div> <p style="text-align: justify;">Unter <strong>Gestein</strong> verstehen wir eine auf natürliche Art entstandene „Mischung“ von Mineralien, Bruchstücken von Mineralien, Resten von Organismen oder gar Bruchstücken von anderen Gesteinen. Der Anteil der jeweiligen Gemische ist je nach Gestein relativ gleichmäßig, dadurch sehen Gesteine meist recht eintönig aus. Die Kruste unserer Erde besteht aus Gesteinen.</p> <p>Wenn wir Gesteine unterscheiden wollen, dann müssen wir uns überlegen</p> <ul> <li>wie sind diese gebildet worden und</li> <li>wie grob sind die Körner ? (das nennt man Textur).</li> </ul> <p style="text-align: justify;">Meist reden wir von magmatischen, sedimentären oder metamorphen Gesteinen. Das witzige an der Geschichte mit den Gesteinen ist, dass sie sich im Laufe von Millionen von Jahren verändern. Ganz am Anfang steht Lava, auch <strong>Magma</strong> genannt. Daraus bilden sich <strong>magmatische</strong> <strong>Gesteine</strong>. Wenn dann Wind, Wasser oder Frost die Gesteinsbrocken zerkleinern, irgendwo hin transportieren und die sich dort wieder verfestigen, dann reden wir von <strong>Sedimentgesteinen</strong>. Und wenn im Laufe der Zeit dieses Sediment dann durch Hitze und Druck sich verändert, dann reden wir von <strong>metamorphen Gesteinen</strong>. Schau Dir mal dir Zeichnung an, dort siehst Du, wie sich die Gesteine verwandeln können.</p> <p>Die genauen Unterschiede erklären wir Dir dann in den nächsten Seiten.</p> <div id="attachment_861" style="width: 650px" class="wp-caption alignnone"><img decoding="async" aria-describedby="caption-attachment-861" class="wp-image-861" src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://vfmg.de/wp-content/uploads/2020/02/Kreislauf-der-Gesteine-1.png" alt="" width="640" height="480" data-srcset="https://vfmg.de/wp-content/uploads/2020/02/Kreislauf-der-Gesteine-1.png 960w, https://vfmg.de/wp-content/uploads/2020/02/Kreislauf-der-Gesteine-1-768x576.png 768w, https://vfmg.de/wp-content/uploads/2020/02/Kreislauf-der-Gesteine-1-300x225.png 300w" data-sizes="(max-width: 640px) 100vw, 640px" /><p id="caption-attachment-861" class="wp-caption-text">Kreislauf der Gesteine (Skizze Hohl)</p></div> <nav class="pagination group"> </nav> <div class="clear"></div> </div> </article> </div> </main> <div class="sidebar s1 collapsed" data-position="left" data-layout="col-3cm" data-sb-id="s1"> <button class="sidebar-toggle" title="Seitenleiste erweitern"><i class="fas sidebar-toggle-arrows"></i></button> <div class="sidebar-content"> <div id="media_image-15" class="widget widget_media_image"><a href="https://steinkern.de"><img width="400" height="117" src="https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3.jpg" class="image wp-image-2723 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3.jpg 400w, https://vfmg.de/wp-content/uploads/2022/04/Steinkern-Button-3-300x88.jpg 300w" sizes="auto, (max-width: 400px) 100vw, 400px" /></a></div><div id="media_image-19" class="widget widget_media_image"><a href="https://terra-mineralia.de"><img width="479" height="125" src="https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426.jpg" class="image wp-image-2711 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426.jpg 479w, https://vfmg.de/wp-content/uploads/2022/04/tm_Webbanner_Image_Kombi_KHtm_230x60px_Aufschluss_220426-300x78.jpg 300w" sizes="auto, (max-width: 479px) 100vw, 479px" /></a></div><div id="media_image-18" class="widget widget_media_image"><h3 class="widget-title">Unsere Partner</h3><a href="https://kristall-labor.de"><img width="2300" height="600" src="https://vfmg.de/wp-content/uploads/2023/01/nsmail.png" class="image wp-image-3060 attachment-full size-full" alt="" style="max-width: 100%; height: auto;" decoding="async" loading="lazy" srcset="https://vfmg.de/wp-content/uploads/2023/01/nsmail.png 2300w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-300x78.png 300w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-1024x267.png 1024w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-768x200.png 768w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-1536x401.png 1536w, https://vfmg.de/wp-content/uploads/2023/01/nsmail-2048x534.png 2048w" sizes="auto, (max-width: 2300px) 100vw, 2300px" /></a></div><div class="tribe-compatibility-container" > <div class="tribe-common tribe-events tribe-events-view tribe-events-view--widget-events-list tribe-events-widget" data-js="tribe-events-view" data-view-rest-url="https://vfmg.de/wp-json/tribe/views/v2/html" data-view-manage-url="1" data-view-breakpoint-pointer="d47b03fa-fcee-4583-905e-39a88d572efa" > <div class="tribe-events-widget-events-list"> <script type="application/ld+json"> [{"@context":"http://schema.org","@type":"Event","name":"46.
