harden?
When rock layers are folded, a geological fold happens. These folds form under various conditions such as stress, hydrostatic pressure, pore pressure, and temperature gradient.
they are pushed down
Then fluid can travel through the rock, and the rock is said to be "permeable".
It breaks apart
Along a fault, rock layers can become displaced, offset, or tilted. This is due to the movement of the Earth's crust along the fault line, resulting in different rock layers being shifted relative to each other.
faults occur when this happens
I found that folding happens
fault-block mountain.
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
In an artesian formation, the rock layers are inclined or tilted, creating a confined aquifer with pressure that can cause water to rise naturally to the surface. In an ordinary aquifer, the rock layers are typically horizontal, allowing water to flow more freely without the same pressure dynamics as in artesian formations.
The magma forms sills and magma chambers.
They melt. Coal turns to diamond.
