Clay can be light grey, dark grey, brown, orange, olive, cream, ochre, red and many other colours. If the clay is exposed – without that vegetational cover, it is either in dry or moist form. Dry form has special properties: the upper surface cracks with very clear and distinctive cracks.
Is clay found in nature?
Clays and clay minerals occur under a fairly limited range of geologic conditions. The environments of formation include soil horizons, continental and marine sediments, geothermal fields, volcanic deposits, and weathering rock formations. Most clay minerals form where rocks are in contact with water, air, or steam.
