When did the first Shield Volcano Erupt?
bi lava
Why do some volcanoes erupt while others erupt quietly?
This is because of the time of volcano it is and the type of lava it excretes. A steep volcano will erupt with basaltic lava which is runny and can clog at the top. A shield volcano, however is different as the thick lava emitted just glops onward.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
What type of volcano has lava that primarily consists of basalt?
Both shield volcanoes and cinder cones primarily erupt basaltic lava.
What type of explosion does a shield volcano have?
Generally shield volcanoes do not explode. They erupt in a non-explosive fashion, fountaining or oozing lava.
When volcano erupt they expel what zircons or lava?
lava
What does a shield volcano create?
A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. They are named for their large size and low profile, resembling a warrior's shield. This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from more explosive volcanoes. This results in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. It basically creates it self but in a bigger form.
What does the fissure in a volcano do?
A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. They are named for their large size and low profile, resembling a warrior's shield. This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from more explosive volcanoes. This results in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes contain low viscosity magmamaking it have flowing mafic lava.
What happens to lava when a volcano erupt?
lava shoots out of the top
What makes a volcano to erupt?
the hot lava
When does a volcano erupt quietly?
If it has liquid Lava
What is the similarities to the Cinder Cone Volcano the Composite Volcano and the Shield Volcano?
- They all are made up of layers of volcanic debris - They all erupt lava - They all have played important roles in volcanology - They are all hazardous
