refers to the alterations caused by high pressure during earth movements.

Explanation:
The shape of the earth's surface is not only because of forces of erosion wearing away the surface, but because of the processes from within the earth, which might raise or lower the surface. Violent movements such as those associated with earthquakes cause damage to buildings, tidal waves, and changes in landforms. Examination of sedimentary rocks shows that the layers that were formed horizontally under water have sometimes been folded. This has been caused by enormous pressure in the earth's crust resulting in slow bending of the rocks. The dip of a bed of rock is the greatest angle of inclination at which the bed is tilted from the horizontal. The strike of a bed of rock is the direction of a horizontal line on the bedding plane. Metamorphic rocks are formed as a result of great heat and pressure on existing rocks within the earth's crust.
