They have been created during the formation of the earth millions and even billions of years ago. Earthquakes and tectonic plate shifts may help form volcanoes, and may even erupt them.
Volcanoes are usually cone shaped mountains or hills.
Volcanoes are cone-shaped mountains that can eject lava, ash, and gases from a vent in the Earth's crust. They are formed by the accumulation of erupted material over time.
The main kinds of volcanoes according to shape are shield volcanoes, which have a low, broad profile; stratovolcanoes (or composite volcanoes), which are tall and conical with steep slopes; cinder cone volcanoes, which are small, steep-sided cones made of pyroclastic material; and calderas, which are large, basin-shaped volcanic depressions usually formed by the collapse of a magma chamber.
The volcanoes described are known as cinder cone volcanoes. They are characterized by their steep sides and conical shape, formed from the accumulation of volcanic ash, cinders, and volcanic bombs ejected during eruptions. These materials fall back around the vent, creating the cone structure. Cinder cone volcanoes are generally smaller than other types of volcanoes and can erupt relatively frequently.
Cinder cone volcanoes form from the accumulation of cinders and tephra during an explosive volcanic eruption. This material is ejected from the volcano and falls around the vent, building up a cone-shaped structure. Examples of cinder cone volcanoes include Paricutin in Mexico and Sunset Crater in Arizona.

They are shield volcanoes. This means that they are cone shaped but with very shallow slope angles forming the volcanoes flank.

Three landforms that can be created from ash are cinder cone volcanoes, composite volcanoes, and shield volcanoes. Lava plateaus can also be formed.

Cinder Cone
Erebus is shaped like most volcanoes -- like an upside-down cone.
