Ø What is the relationship between craters, calderas, vents, and magma?bowl shaped depression=crater, larger than 1 km=calderas, vent is near or the crater, magma is the hat lava cooling from a volcanoe.
Ø How does a crater lake form? (words and pictures)numerous volcanic eruptions
Ø What two factors does a volcano’s appearance depend upon? What characteristics vary among volcanoes?type of material and type of eruptions,size shape composition
Complete the following table in your notes:
Type of Volcano Materials & Description Sketch Example
Shield broad gently sloping slides circular base
Cinder-Cone material ejected into the air falls back and piles up round vent
Composite (Stratovolcano) volcanic fragments alternate with lava
Ø How do the volcanoes compare in terms of size and slope?the slopes and the size and also the climate region and temperature
Ø What factors cause differences in size and slope? the slopes temperature and region
Ø What is tephra?rock fragments thrown into the air during a volcanic eruption
Ø What is a pyroclastic flow?rapidly moving volcanic material
Ø Where are most volcanoes found?along convergent boundaries and some divergent boundaries
Use the maps provided to show: (1) the Circum Pacific Belt and the Mediterranean Belt where convergent volcanism occur and (2) the Hawaiian Emperor Volcanic Chain.
Ø How do hotspots form?volcanoes are located far from the plate boundaries,these volcanoes form hot spots
Ø What do hotspots tell us about tectonic plates?plates move over hot spots so when volcanoes form over a hotspot
