What else can I help you with?
Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
How do active volcanoes located on islands create more land area on these islands?
Active volcanoes on islands create more land area through the deposition of lava, ash, and other volcanic materials. When volcanoes erupt, the flowing lava solidifies and cools, forming new land masses on the island. Over time, repeated eruptions can contribute to the growth and expansion of the island.
Do volcanoes produce large amounts of ash when they erupt?
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
What are the three major types of valcanos?
The three major types of volcanoes are shield volcanoes, cinder cone volcanoes, and stratovolcanoes. Shield volcanoes have broad, gently sloping sides and are primarily composed of basaltic lava. Cinder cone volcanoes are small, steep-sided volcanoes that erupt primarily cinder-sized fragments. Stratovolcanoes are tall, conical volcanoes composed of alternating layers of lava flows, volcanic ash, and other materials.
What materials came out when volcanoes erupt?
Lava, ash, pumice and molten debris.
What is the source of materials for volcanoes that erupt in non-explosive and explosive?
Magma and lava also crust?
What type of materials are released when volcanoes erupt?
Gaseous matter such as H2O, SO2, CO2. Solid materials such as ash, lava, bombs.
Do you know when volcanoes erupt?
When lava spews out of it.
What lava is in fissure volcanoes?
Fissures usually erupt basaltic lava.
How do volcanoes shape the Pacific Northwest?
volcanoes will erupt and let out lava then the lava will harden and that will be new land.
How do volcanoes form a hole at the top?
When Volcanoes erupt the surface is melted by the lava
What erupts from volcanoes along with lava?
Volcanoes can erupt ash, gas, and pumice in addition to or instead of lava.
Do volcanoes erupt just lava?
No. Volcanoes also release ash and a variety of gasses.
Does a shield volcano have runny lava?
In volcanoes that have lower amounts of volcanic gases in the magma. A good example is the volcanoes in the Hawaiian islands. Volcanoes with more gases in the magma tend to erupt explosively (Mt. St. Helens, Vesuvius) and have a thicker, slower moving lava.
Why do strato volcanoes erupt?
by pressure of molten lava of the dence viscocity.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
