one of them is clay
clay is homogeneous mixture
Over millions of years, clay-like material that falls to a lake bottom is subject to intense pressure and heat. This results in an incredibly slow and gradual process of change. The clay-like material will transform into a sedimentary rock, such as shale or mudstone. These rocks are composed of particles of clay and other minerals that have been cemented together as a result of the pressure and heat. The sedimentary rock will also contain fossils and other evidence of the organisms that were present at the time the clay-like material was deposited. This is because the process of sedimentary rock formation preserves and encases the fossils and other organic material that was present in the clay-like material when it was deposited. Thus, after millions of years of pressure and heat, the clay-like material that fell to a lake bottom is transformed into a sedimentary rock containing fossils and other evidence of past life.
the best material is sandstone

It was mostly clay/mud bricks.
Clay. This is why people have used it for a building material for thousands of years. Bricks, adobe, and "mud huts" are all made of clay-type soils.

A brick is not a rock. It is a building material made out of baked clay.
Clay is a good material for building models and such because it is very tough. However, it is still a very moldable substance. It shapes easily. But if clay get too cold it will either crack, or it will get to tough to mold. Always keep the room at around 69-72 degrees. Have fun. -Devin Sgueglia
Clay is not a good material when making a road. When clay dries, it is easily broken. Clay is also not a strong enough material for lots of heavy vehicles to be on it.
the Sumerians used clay that was dried as a shape of a brick and it made them a comfy house
