StratovolcanoAlso known as composite, stratovolcanoes are conical and shape.

They are built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash.

Known for periodic explosive and quiet eruptions.

Names for their large size and low profile, resembling a shield lying on the ground.

Lava flows more quickly due to low viscosity.

They are relatively explosive, but fall near the crater.

The explosive bits that come out splash over the side and due to them being partly liquid rock, they form mounds called spatters.

The Hawaiian Islands are composed of linear chains of shield volcanoes, including the largest active volcano on the planet, Mauna Loa.

Olympus Mons on Mars, is also a shield volcano.

Fun Facts:

There are around 100 identified cinder cones on the flanks of Mauna Kea.

Fun Facts:

Mount Vesuvius, perhaps the most well known volcano, is a stratovolcano.

Mount Fuji, another well known stratovolcano, last erupted in 1707-1708.
