How does the process of mountains being formed cause earthquakes?

earthquakes occur as the plates pull away from each other.

Explanation:

Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.

Second, only earthquakes occur when two plates collide (obduct), building a mountain range.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
