Basaltic magma erupts along mid-ocean ridges primarily due to tectonic plate divergence, which creates space for magma to rise from the mantle. As the plates pull apart, the pressure decreases, allowing the mantle rock to partially melt and form basaltic magma. The relatively low viscosity of basaltic magma facilitates its ascent, leading to frequent eruptions and the formation of new oceanic crust at these ridges. Additionally, the continuous supply of heat from the mantle ensures ongoing volcanic activity in these regions.
What else can I help you with?
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.
The volcanoes of Hawaii form fron thin basaltic magma that tends to erupt quietly What is one reason for the quiet eruptions?
Basaltic magma allows dissolved gases to bubble upward and escape
What type of volcano has lava that primarily consists of basalt?
Both shield volcanoes and cinder cones primarily erupt basaltic lava.
What happened when shield volcano erupted?
Its starts off gently rising, smooth-sloped volcanic dome formed from very fluid (low viscosity) basaltic lava typical of mid-ocean ridges and hot spots. when a shiled volcano erupts they are probably the most violent/distrustive. Sheld volcanoes continue to erupt. -divergent plate boundaries -very large -continous -Violent/dangerous
How many under water volcanoes erupt a year?
AnswerRight now, Kiluea has erupted non-stop for at least 30 years.
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.
Can a stratovolcano erupt blocky lava?
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
What lava is in fissure volcanoes?
Fissures usually erupt basaltic lava.
The volcanoes of Hawaii form fron thin basaltic magma that tends to erupt quietly What is one reason for the quiet eruptions?
Basaltic magma allows dissolved gases to bubble upward and escape
Will rhyolitic magmas erupt at lower temperatures than basaltic magmas?
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.
What type of volcano has lava that primarily consists of basalt?
Both shield volcanoes and cinder cones primarily erupt basaltic 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.
How are shield volcanoes and cinder cone volcanoes somewhat same?
Both erupt basaltic lava, which has a low silica content and a high temperature.
Does AAA lava erupt quietly?
Generally yes. A'a and pahoehoe are both varieties of basaltic lava, which usually erupts fairly quietly.
Were can volcanoes erupt?
Along plate boundries.
Does molten material erupt inside the central valley of mid-ocean ridges?
Yes, molten material does erupt inside the central valley of mid-ocean ridges. This molten material comes from the Earth's mantle and rises to the surface through the cracks in the oceanic crust, creating new crust as it solidifies.
Where do volcanes erupt?
Along some plate boundaries.
