Explanation: Barring the basalt flows, the shield volcanoes are the largest of all the volcanoes on the earth. The Hawaiian volcanoes are the most famous examples.

• These volcanoes are mostly made up of basalt, a type of lava that is very fluid when erupted. For this reason, these volcanoes are not steep.
• They become explosive if somehow water gets into the vent; otherwise, they are characterised by low-explosivity.
• The upcoming lava moves in the form of a fountain and throws out the cone at the top of the vent and develops into cinder cone.
