Answer 2

Answer:

A shield volcano is a very large, gently 'sloping mound' composed mainly of 'basaltic lava flows'.  

Explanation:

• The volcanoes are broadly classified into four major types, viz. Cinder Volcanoes, Composite Volcanoes, Lava Domes, and Shield Volcanoes.

• Out of these four, the Shield Volcanoes are the largest in size and span.

• The low viscosity of the lava that comes out of Shield Volcanoes is due to the presence of a high amount of molten basalt in the lava.
