WebFeb 2, 2024 · Although quartz is more resistant to weathering than many other minerals, it still weathers with many impacts on plants and soils. Dissolved silica from quartz and other silicate minerals is used by some plants for structural tissues. As an example, rice accumulates silica to strengthen its stem (Lanning, 1963). Dissolved silica also can affect ... WebSep 28, 2024 · 7.1.3: Ease of Weathering. Some minerals break down more easily than others. Geologists can compare weathering rates by looking at minerals in rock outcrops, and by studying the minerals present in sediments of different ages. Goldich (1938) made such observations, publishing what we call Goldich’s Weathering Series.
