Compressional stress
Tensile stress.
P or Primary waves are longitudinal waves that move rock particles back and forth in the same direction that the wave travels.
Tensile stress.
Gravity
p waves because they move rock back and forth which squeezes and strecthes the rock as they travel through the rock. s waves shear rock side to side as they travel through the rock
P or primary seismic wave.
A plutonic intrusion.Igneous rock.
an earthquake
sill
The force that squeezes a rock until it folds or breaks is called compression. When enough stress builds up in a rock, the rock can break, and create a fault.
Mountains
Compressional stress
A sill is formed.
when sedimentary melts the heat squeezes the rock then it becomes a metamorphic rock.
Stress forces squeeze or pull the rock in the Earth's crust.
A sill (assuming you are talking about horizontal layers of rock)
