What else can I help you with?
How could you tell if a volcano makes felsite or basalt lava?
Thin lava
Very broad volcano with gentle slopes formed from basalt lava flows.?
it is a shield volcano
What type of rock results from the cooling of lava from a volcano?
Igneous rock, such as basalt or andesite, results from the cooling of lava from a volcano.
What should you know about volcano?
it is explosive! and shoots out lava and magma.
What is a quiet volcano?
Quiet volcanoes explode with much less suddenness, because lava does not cool and harden. The lava that creates a quiet volcano is still runny and flowing, and do not plug the craters and trap huge quantities of explosive gas. However, pockets of hot gas form that squirt fountains of lava into the air. Because lava flows away before hardening, broad sheets of lava and wide, gently sloping domes are formed around the volcano. When the lava has dried, it forms a rock known as basalt.
Where would you expect to find lava solidifying into basalt?
You would expect to find lava solidifying into basalt at the surface of a volcano or lava flow. Basalt is a common volcanic rock that forms when lava cools and solidifies quickly, usually in areas with high volcanic activity.
How could you tell if a volcano makes felsite or basalt lava?
Thin lava
Very broad volcano with gentle slopes formed from basalt lava?
shield volcano
Where is basalt born?
Basalt is formed when low-silica lava erupts from a volcano and later cools.
Do basalt plateaus form from explosive or quiet eruptions?
Quiet eruptions are a characteristic of basalt lava flows and plateaus.
Very broad volcano with gentle slopes formed from basalt lava flows.?
it is a shield volcano
What type of rock results from the cooling of lava from a volcano?
Igneous rock, such as basalt or andesite, results from the cooling of lava from a volcano.
Why do scientists need to know the different types of lava flow?
The type of lava flow lets you know the different type of volcano. Not all volcanoes are "explosive". Basalt volcano you can practically stand and watch as it explodes. Where as an andesite volcano you want to be far away. Also the different lava flow lets you know where the melting is occurring. If the flow is high in granitic composition it means the continental crust has melted. If the flow is high in basalt it is a oceanic crust melt.
Is a non-explosive volcanic eruption more likely to produce lava or pyroclastic material?
Lava because pyroclastic material explodes from a volcano, Lava just runs down the surface of the volcano nonexplosive or explosive.
A types of volcano with broad gentle slopes and built by the eruption of fluid basalt lava?
a shield volcano
What should you know about volcano?
it is explosive! and shoots out lava and magma.
What is a quiet volcano?
Quiet volcanoes explode with much less suddenness, because lava does not cool and harden. The lava that creates a quiet volcano is still runny and flowing, and do not plug the craters and trap huge quantities of explosive gas. However, pockets of hot gas form that squirt fountains of lava into the air.
