PRESENTATION OUTLINE
CINDER CONE
- Cinder Cone volcanoes are the most common type of volcano.
- They are steep sided cones of basaltic fragments.
- They are relatively small, usually less than 1,000 feet height, with very steep sides and a cylinderical shape.
- They are built from piles of ejected rock fragments.
- When they erupt lava, it usually flows not from the summit but from a breach in the side or base of the volcano.
CINDER CONE
- Rock fragments projected are glassy and contain gas bubbles
- These volcanos are made from pyroclastic material
- Lava does not typically emerge from the top
- Too week to support the pressure
- Creates lava flow around the base
CINDER CONE VOLCANO
- Compared to shield volcanoes, Cinder cones have more viscosity and gas.
- These volcanoes are much smaller than shield and stratovolcanoes and are steep.
- The type of eruption in this volcano is called Stromblian eruption.
- While lava tries to escape, lava sprays out in a series of booming eruptions
- Examples of this type of this include Stromboli and Paricutin.
Untitled Slide
- Steep sided cones of basaltic fragments
- Melted volcanic rock that cooled and formed pebble sized pieces when it is thrown out into the air.
- Comes from a single vent and accumulates around the vent when they fall back to earth
- Ex: Toal (Philippines)
