Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Cinder-Cone Volcanoes and Composite Volcanoes
Do shield volcanoes have a lot of silica or water?
Water.
What kind of volcano form from lava that is higher in water and silica content than lava that forms shield volcanoes?
cinder cone
How many volcanoes erupted so far?
well , that is a good question ! About 1,300 has happened in the last 10,000 year. Most of these are shield volcanoes. Shield volcanoes are found under water or and form easily. three quarters ( 3/4 ) of volcanoes are shield volcanoes. SO if you subtract all of the shield volcanoes from the amount of volcanoes that have happened in the last 10,000 years it will come up to 6,000 eruptions in the last 10,000 years. This is not including under water or shield volcanoes. WELL, that's all . BYE ! (:

Is a shield volcano nonexplosive or explosive?
shield volcanoes are only explosive if water somehow gets into the vent
How a shield volcano is formed?
shield volcanoes are formed by lava flows or low viscosity lava that flows easily...
Is a shield volcano non explosive or explosive?
Shield volcanoes are generally not explosive. However, soemtimes a type of explosive event called a phreatic eruption can occur if the magma comes in contact with water.
Do volcanoes disappear?
Volcanoes don't not exactly "close up" but either get clogs up when the rising magma cools or collapse. When the volcanoes collapse it forms a caldera. These calderas can fill with water making a lake.
What type of eruption and lava do shield volcanoes produce?
Shield volcanoes erupt in a flowing, non-explosive manner, the lava flowing for extremely long distances creating the gentle shield shaped form. Eruptions at shield volcanoes are only explosive if water somehow gets into the vent, otherwise they are characterized by low-explosive fountaining that forms cinder cones and spatter cones at the vent. In a shield volcano, 90% of the volcano is lava rather than pyroclastic material. Due to high magma supply rates, the lava is hot and changes very little after it is generated. A common product of hotspot volcanism, shield volcanoes can also be found along subduction-related volcanic arcs or all by themselvesShield volcanoes usually erup by fountaining or extruding lava.
Is Ireland a volcanic island?
It was probably at one time because all islands are formed by under water volcanoes.
