Good luck! If the crystals are small or impossible to see without a magnifying lens, the rock is . Finally, biological weathering occurs when animals or other living things affect the rocks they encounter. Rainwater, for instance, can be acidic, and acid rain can break down certain rocks for this reason. ANSWER. Learn. Both calcium oxide (CaO) and alumina (Al2O3) are depleted in the rocks that have a silica content of less than about 45 weight percent, but, above 45 percent, calcium oxide can be as high as 10 percent; this amount decreases gradually as the silica increases. And, of course, humans can cause weathering through construction and other activities. 2.6.2 Lesson: Igneous Rock Flashcards | Quizlet Some of the most common intrusive rocks include diorite, gabbro, granite, pegmatite, and peridotite.

Igneous Rocks, Free PDF Download - Learn Bright Magma is thought to be generated within the plastic asthenosphere (the layer of partially molten rock underlying Earths crust) at a depth below about 60 kilometres (40 miles). The major oxides of the rocks generally correlate well with their silica content: those rocks with low silica content are enriched in magnesium oxide (MgO) and iron oxides (FeO, Fe2O3, and Fe3O4) and are depleted in soda (Na2O) and potash (K2O); those with a large amount of silica are depleted in magnesium oxide and iron oxides but are enriched in soda and potash.
