Tektonisme is a change or movement of the earth layers horizontally and vertically. In general, the form of the energy output in the form of faults and folds tektonisme. Fault is a form of vertical movement (up and down), for example, the movement of the Earth's surface up or down. Fault events occur in the strata are very large and take place in quick time, causing layers of the earth cracked or broken. The earth's surface that had fractures called graben or down slenk, while the surface of the earth is broken up called horst.
Crease occurs because the Earth's surface pressure horizontally, so that the Earth's surface having folding. Crease is the movement of the layers of the earth are not too great and lasts for a long time, causing the layers of the earth wrinkled or folded, wrinkles or skin folds on earth that will become mountains. Section called antiklinal high and the low (valley) called sinklinal. Sinklinal vast area called geosinklinal. There are several types of folds are upright folds, creases tilt, fall, hang, and folds isoklin.
There are two kinds of motion tektonisme, as follows:
a. motion epirogenetik
Epirogenetik motion is motion or shift the earth's crust is relatively slow and lasted for a long time as well as covering a vast area. There are two kinds of motion epirogenetik, namely:
1. epirogenetik positive, so that the land is falling motion as if the sea levels rise. This event was evident on the beach.
2. epirogenetik negative, so that the land is rising movement as if the sea level dropped.
b. motion orogenetik
Orogenetik motion is motion or relatively rapid shift in the earth's crust and cover large areas. This movement causes the pressure horizontal and vertical.
