erosion


earthquake


volcanic activity

Answer 1

Most of the time is earthquakes.

Answer 2

Generally, an earthquake is the geological occurrence that creates a fault line.

Step-by-step explanation:

• A fault line occurs when the tensional stress in the rocks transcends the elastic capacity of the rocks and a fracture is caused.

• For a fault line to occur, there has to be a tensional pressure.

• When a tremor or an earthquake invigorates the tensional pressure from the rock to be released, a rock cracks up in two parts and a fault line appears on the Earth's surface.
