Tektonisme is a process that occurs due to the movement, removal, folds and faults in the structure of the soil in an area.
Symptoms tektonisme starting from the upward pressure of the magma, plate motion, and the energy collected will be able to suppress the layers of the earth so that there is a change or shift the location of the earth's crust. As a result, the earth's crust can be curved (called folds) or broken (known fault).

3)      Collapse earthquake
The earthquake caused by the collapse of limestone caves and landslides.

  1. Expalin the signs of erupting volcano!
    • Answer :
1)      Such as increasing temperature around the crater.
2)      Many water sources around the mountain were dried
3)      Volcanic earthquake frequently occurs
4)      The roar voice often heard from inside of the mountain.
5)      Many animals go down the mountain slope.

  1. What is the impact of exogenous power!
    • Answer :
1)      Earth relief is various such as lowland, hills, mountain range, plateau, and also high and snowy mountains.
