WebThe processes for building new land are called constructive forces. Three of the main constructive forces are crustal deformation, volcanic eruptions, and deposition of sediment. Crustal deformation occurs when the shape of land (or crust) is changed or deformed. One of the main causes is movement of the Earth's plates. WebThe 275,000 year old geologic history of Mount St. Helens has displayed both relatively quiet outpourings of lava and violent explosive eruptions of volcanic ash and rock fragments, known as tephra. Volcanologists have separated the eruption history of this volcano into four main stages, each followed by a dormant, nonexplosive period.
