What explains how cinder come volcanoes obtain their shape

• the eruptions being mostly of ash

• The eruptions being moderate or mildly explosive

• The silica content of the lava that comes out

• The addition of water makes the lava flow much quicker

What explains how shield volcanoes obtain their shape

• The moderate violent eruptions that come out of the volcano

• The lava is so thick that it crystallizes and cools super quick

• The gentle ooze and flow of the lava out of the volcano

• The weathering and erosion of the rocks form the volcano

You travel to Oregon and look at a volcano that has very steep slopes and is very massive in size what would you classify those volcanoes as

• Shield volcanoes

• None of the above

• Composite cone volcanoes

• Cinder cone volcanoes

You travel to Hawaii and look at several volcanoes that have very steep slopes what would you classify those volcanoes as

• None of the above

• Shield volcanoes

• Composite cone volcanoes

• Cinder cones volcanoes

• Cinder come

• Composite cone volcanoes

• Shield volcanoes

• None of the above

How are temperature changes a good short term prediction for a volcanic eruption

• Due to rise of hot material from within the earth comes up and raises the temperature

• The ash is showing that something is being burned and we need to leave

• Temperatures will always spike downward before an eruption takes place

• Temperatures flux all the time it is just by chance something’s eruptions take place

How is an increase in gas and or ash emission a good short term prediction for volcanic eruption

• The gas is a sign of methane being released from the mantle

• The ash is showing the something is being burned and we need to take it series

• The increased gas and ash are indicators of great pressure being released

• The gas and ash has nothing to do with volcanoes
