Stratovolcano

Also 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.

Stratovolcano Cntd.

Lava that flows from stratovolcanoes typically cools and hardens
before spreading far due to high viscosity.

Fun Facts:
Mount Vesuvius, perhaps the most well known volcano, is a
stratovolcano.
Mount Fuji, another well known stratovolcano, last erupted in 17071708.

Shield

Usually built entirely of fluid lava flows.

Names for their large size and low profile, resembling a shield lying
on the ground.

Lava flows more quickly due to low viscosity.

Shield Cntd.

Fun Facts:

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.

Spatter

Formed of molten lava ejected from a vent, with a viscosity
somewhat like taffy.

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.

Spatter Cntd.

Fun Facts:

A famous spatter volcano has the wonderful name, Puʻu ʻŌʻō.

This volcano has been fairly active in recent years.

Cinder

Cinder Volcanoes, are also known as volcanic cones.

They are built up by ejecta from a volcanic vent piling up around
the vent in the shape of a cone with a central crater.

Cinder cones are commonly found on the flanks of shield
volcanoes.

Cinder Cntd.

These volcanoes are usually very small, but very steep.

Fun Facts:

There are around 100 identified cinder cones on the flanks of Mauna
Kea.
