(select all that apply.) other minerals, such as feldspars, will break down to clays quartz is chemically resistant to weathering quartz is very soft and breaks down easily

Answer 1

Because quartz and feldspar are the minerals that resist weathering the most at the Earth's surface, they make up the majority of sandstone.

Because quartz is an extremely strong and chemically resistant crystal, quartz grains make up the majority of sandstones. Sandstones made entirely of pure quartz are referred to as quartzite. Numerous sandstones include tiny bits of other minerals, such as mica, calcite, or clay.

A sedimentary rock known as sandstone is mostly made of quartz sand, however, it can also include substantial quantities of feldspar, silt, and clay on occasion. Quartzose sandstone is sandstone that includes more than 90% quartz.

Sandstones are composed of lithified quartz grains with sizes ranging from 0.06 mm to 2 mm.
