Three different types of volcanoes exist; Volcano An opening in Earth’s crust through which igneous matter (lava, ash, cinder, and gases) are erupted.

The Parts of a Volcano. What is a Volcano?  A mountain that forms when magma reaches the surface of the Earth.  Magma rises because it is less dense.

3 TYPES OF VOLCANOES. SHEILD HOW DO THEY FORM? Thin layers of lava pour out a vent and harden on top of previous layers.

They are the most common type of volcanoes. Many cinder cones have a bowl-shaped crater at the summit. They are commonly found on the flanks of shield.

There are 2 types of volcanismThere are 2 types of volcanism Intrusive----magma cools below the surface and makes plutons (igneous intrusions) Extrusive---liquid.

The structure and emplacement of cinder cone fields. An overview by Richard Fletcher

Study objectives Identifying differences in emplacement and structures between flank cinder cones and flat lying volcanic field cones. Flank cones studied around: Mauna Kea. Hawaii; Mt. Etna, Italy; Kilimanjaro, Tanzania. Platform cones studied around: San Francisco Mtn., Arizona; Paricutin region, Mexico; Nunivak Island, Alaska.

Overview of Climatic conditions and ages of cones

Primary Study Areas

Implications Lunar cones have smaller rim heights and larger basal diameters due to less gravity and atmospheric drag. Morphometeric analysis suggests the shape and size is a function of age and erosive processes. Younger cones indicate active volcanism methods (conduits and dikes).
