Chemistry

Elan Coil [88]2 years ago

Answer:

Explanation:

Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied  being so far underground. Therefore, creating what we now know as Slate.
