Why do strato volcanoes erupt?
by pressure of molten lava of the dence viscocity.
What are lava flows on a volcano?
A lava flow is where lava flows down the side of a volcano.
What makes a quiet eruption different from an explosive eruption?
quiet eruption flows easeir cause it has a low viscosity and lava flows easier but explosive eruption has a high viscosity and lava flows slower
The different types of eruptions that result from different types of lava?
Different types of lava result in different types of volcanic eruptions. Basaltic lava, which is low in viscosity, typically leads to effusive eruptions characterized by gentle flows. Andesitic or dacitic lava, with higher viscosity, can cause explosive eruptions with pyroclastic flows and ash clouds. Rhyolitic lava, the most viscous type, tends to form dome eruptions with slow-moving lava flows and explosive activity.
Opening where the lava flows?
the opening where the lava flows is call a vent
What is Magma that flows onto Earth's surfaces called?
Magma that flows onto Earth's surface is called lava.
What are the different types of lava?
A'a Pahoehoe Pillow Lava The difference between the lava is the elements and amount of water inside the volcano. Also, the thickness of the lava.There are 4 different types of lava flows maybe more
Are all lava flows the same?
No. Lava flows vary in composition. Most lava flows consist of basaltic lava, which can flow as smooth phoehoe or form jagged and broken a'a. Other lava flows are more viscous and will have blocky surfaces and tend to be short and thick.
Do cinder cone volcanoes have AA lava or pahoehoe lava?
Pahoehoe and a'a refer to different texutres of lava flows. Although cindercones can produce lava flows, their main mode of eruption is called "fire fountaining" which tends to produce chunks of lava called scoria, rather than pahoehoe or a'a.
What is the name of mountain from which the lava flows out?
A volcano is a mountain from which lava flows out during an eruption.
What can stop lava flows?
Lava flows can be stopped or deflected by ridges, valleys and depressions in the ground.
What happens when lava flows reach the sea?
When lava flows reach the sea, the lava rapidy cools to form an igneous rock.
