1. The domed internal landform created by volcanic activity is called a batholith.

2. The process of volcanism includes the process from the formation of magma and gas in the Earth's interior to the formation of lava coming to the Earth's crust and the landforms resulting from it. The explosiveness of a volcano is determined based on the amount of silica in the magma.

3. Classification of volcanoes on the basis of activity -

- Active Volcano: Volcanoes from which lava, gas and fragmented materials are always coming out are called active volcanoes. Stromboli (Sicily), Etna (Italy), Cotopaxi (Ecuador), Barren Island (Andaman Nicobar, India) etc. are examples of active volcanoes.

- Dormant Volcano: This category includes those volcanoes which have not been active for years but can erupt at any time. This category includes Krakatau of Indonesia and Narcondam Island of Andaman.

- Dead Volcano: This category includes those volcanoes in which no eruption has taken place for thousands of years. Chimbarrazo of Ecuador and Kohsultan of Iran are its main examples.
