Classification of volcanoes based on the shape

Volcanoes are caused by sudden movements occurring in the Earth’s interior. Classification of volcanoes based on the shape is discussed below

Classification of volcanoes based on shape:

Central volcano: This volcano is formed when debris and lava erupt out forming a symmetrical volcano.

Fissure volcano: This volcano throws out lava and fragments of rocks through fissures or cracks on the Earth’s surface. Instead of building a cone, the cracks distribute lava over a vast area. The Columbian Plateau was formed by a fissure eruption.

Shield volcano: When a volcano emits large quantities of hot lava, a large shield-like structure is spread over large parts of the Earth. Mauna Loa in Hawaii Islands is a shield volcano.

Conical volcano: Because of repeated eruptions, a volcano may acquire a cone-shaped structure. These volcanoes usually have steep slopes. A conical volcano is also known as a composite volcano. Mt Fuji in Japan is an example of a conical volcano.



A volcano is a vent or an opening in the Earth’s crust from which hot magma erupts from the interior of Earth. Volcanoes are generally caused because of the following reasons. Read more

Landforms of the Earth

The surface of the earth is not the same everywhere. The earth has an infinite variety of landforms. Some parts of the lithosphere may be rugged and some flat. Read more


Weathering is the gradual wearing and tearing of rocks on the surface of the Earth. The main agents of weathering are temperature, humidity, and precipitation. Read more

The Atmosphere

The blanket of air that surrounds the Earth is known as the atmosphere. It exists in several layers. The atmosphere is made of many gases and solid particles. Read more


Earthquakes are not associated with the weather but instead are natural disasters. An earthquake is a tremor below the surface of the Earth which causes shaking of the Earth’s crust. Read more
