| Häufigkeit chemischer Elemente in der Erdkruste |
| |
Die Erdkruste ist im Mittel ca. 17 km mächtig (unter den Kontinenten ca. 40 km, unter den Ozeanen ca. 10 km). Chemische Analysen von Gesteinen,
Lava, Wasser und von Luftproben aus der oberen Erdkruste
(einschließlich der Wasser- und Lufthülle) liefern Durchschnittswerte für die Häufigkeit des Vorkommens der chemischen Elemente in diesem Bereich..
