What lava is in fissure volcanoes?
Fissures usually erupt basaltic lava.
Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
Can a stratovolcano erupt blocky lava?
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
Lava plateaus forms when?
Lava plateaus form when fluid basaltic lava flows out of fissures.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Where does lava erupt through?
Lava erupts through openings in the Earth's crust, typically from volcanoes or fissures in the ground. This molten rock is forced to the surface by pressure from beneath the crust, often resulting in volcanic eruptions.
When volcano erupt they expel what zircons or lava?
lava
What causes the quiet erupt and loud erupt?
Loud Erupt: The magma is really thick It is cooler lava More silicia Quiet Erupt: Thin Hotter lava low silica
Why do volcnos spit lava?
Volcanoes erupt and spit lava due to the buildup of pressure from molten rock, or magma, trapped beneath the Earth's surface. When this pressure exceeds the strength of the surrounding rock, it causes the magma to rise and escape through fissures or vents. As the magma reaches the surface, it can erupt explosively or flow out as lava, depending on its composition and gas content. The release of gases and the movement of magma are key factors in volcanic eruptions.
What happens to lava when a volcano erupt?
lava shoots out of the top
When large amounts of lava flows out of fissures onto land the lava can cover a large area and form a plain called what?
a plateau
What do they do when the erupt?
its explodes and lava comes out
