Question

56. Feldspars commonly decompose during weathering to clay minerals, silica, and soluble constituents 57. Ferromagnesian minerals (like olivine and pyroxene) that crystallize at high temperatures in Bowen's reaction series are generally much less susceptible to chemical weathering S8. In detail, there is no geologic evidence that mid-ocean ridges spread at uniform rates or 59. As dense seafloor is subducted, it penetrates the surrounding mantle and ruptures it 60. Calcite and halite react with dilute acids to evolve carbon dioxide. False than quartz. even symmetrically. causing the largest earthquakes.as the mantle fractures.
