clay is formed from cementation from the fine grains .
Usually from the weathering (typically chemical, via slightly acidic rainwater) of silicate rich rock, particularly those rich in feldspars.
by the hardening of mudstone.
when god makes it
Chemical Weathering.
Kaolinite/Kaolin.
Quartz and mica. Clay minerals come from decomposing feldspars.
weather rock, gravel ,sand, silt, clay .these are obtained from the parent material the rock from which the soil is derived
Clay minerals.
Clay is the rock.It is formed usually by erosion of felspars and other minerals.
Yes. Compaction and cementation of clay minerals can result in the formation of shale and claystone.
Chemical Weathering.
Clay is made up of clay minerals, and clay minerals are chemically weathered from minerals such mica and felspar.

Shale is a clastic sedimentary rock formed of clay and silt sized eroded particles that are a result of both physical and chemical weathering. The clay minerals, however are the result of chemical weathering of feldspars.

Clay minerals are sheet silicates.
In childrens terms? how bout this... Clay is a special kind of mud that is formed when the dirt is very fine. well. clay is in the soil it is a special mud as it is full of special minerals that is very good for the plants and soil .
