How are volcanoes formed? Lesson 25 – pages 21-22

Lesson Aims To learn how shield volcanoes form. To learn how composite cone volcanoes form. Key Skill = Communication

Rift Valleys

Shield Volcanoes Gentle slopes and wide base Frequent eruptions of basic lava (Mount Elgon is now considered extinct) Lava flows more easily, travels longer distances before cooling Usually non-violent. Layers are of similar basalt lava flows. The basalt weathers to form a very fertile soil. Shield Volcanoes

Shield Volcanoes Draw a labelled sketch of a shield volcano. Describe its characteristics. Explain its characteristics.

Composite Cone Volcano Steep-sided cone shape High with narrow base Alternate layers of lava and ash Lava may cool inside the vent - the next eruption is very explosive to remove the plug Subsidiary cones and vents form. Composite Cone Volcano

Composite Cone Volcano Draw a labelled sketch of a Composite Cone volcano. Describe its characteristics. Explain its characteristics.
