Well, after millions of years, the mud will start to cement together, due to natural cements and will form rock. This can result in footprints, fossils, animal remain, etc to be preserved in the rock.
If u want a better explanation, there is a thing called Wikipedia...
When a river slows down as it runs into a lake, the sediment sinks to the bottom. Over hundreds of years, the sediment is cemented together to form mudstone, a sedimentary rock.
A Mudstone is formed simply by the particles being cemented together. The process is called lithification.
It turns to slate.
sedimentary Rock
Cemented clay and silt particles.
slate
Slate.
metamorphic rock
Guys who want to see me in real life then come to Campion school language college in bugbroke
phyllite
If slate is sufficiently heated and compressed it becomes phyllite.

Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.

Mudstone is hard when its place in the sun
Mudstone is sedimentary
Mudstone is a clasitc sedimentary rock.
Mudstone is a clastic sedimentary rock.
Mudstone is a mudrock. It is made of clay minerals and other very small pieces of rock. Mudstone is sedimentary.
mudstone has smaller particles :D
Phyllite is metamorphosed slate, which is also a metamorphic rock. Shale or mudstone is the protolith (parent rock) of slate.
