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 are the different types of volcanoe?
Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes. They are: Cinder Cones: They are circular or oval cones made up of small fragments of lava from a single vent. They have been blown into the air, cooled, and fallen around the vent. Composite: They are steel-sides and composed of many layers of volcanic rocks. Mt. Rainier and Mount St. Helens are examples of this type of volcano. Shield: Shaped like a bowl or shield in the middle, they have long gentle slopes made of basaltic lava flows. The volcanoes that formed the basalt of the Columbia Plateau were shield volcanoes. Lava Volcanoes: Deep sided mound formed by lava that is too thick to flow. The lava piles up near the vent.
Why are Hawaiian volcanoes shield volcanoes?
Hawaiian volcanoes are shield volcanoes because they are characterized by their broad, gently sloping shape resembling a warrior's shield. This is due to the low viscosity of the basaltic lava they erupt, allowing it to flow easily and travel long distances before solidifying. As a result, shield volcanoes tend to build up gradually over time with successive eruptions, creating their distinctive shape.
What are the three major types of volcanoes?
The three major types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava flows, stratovolcanoes are steep-sided and composed of layers of lava and ash, and cinder cone volcanoes are small, steep-sided cones made of pyroclastic material.
What are types of valcano?
The main types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), cinder cone volcanoes, and lava domes. Shield volcanoes have gentle slopes and are formed by fluid lava flows. Stratovolcanoes are tall, steep-sided cones composed of layers of lava and ash. Cinder cone volcanoes are small, steep-sided cones made of pyroclastic material. Lava domes are mounds of thick, slow-flowing lava piling up near a volcano's vent.
What are shield volcanos made of?
Shield volcanoes are composed mostly of layers of basaltic lava flows.
Do shield volcanoes have a steep sloping cone made up of rocks and lava?
No. Shield volcanoes have gentle slopes composed almost entirely of cooled lava flows.
Shield volcanoes are almost entirely composed of this kind of very fluid lava.?
Basaltic lava (low in silica).

What is similar about cinder cone volcanoes and shield volcanoes?
Both shield volcanoes and cinder cones erupt low-viscosity basaltic lava and have eruptions that are only mildly explosive if at all.Cinder cones are small, steep-sloped volcanoes composed primarily of a chunky variety of basalt called scoria.Shield volcanoes are large, gently sloping volcanoes composed primarily of layers of lava flows.
What do shield volcanoes form?
Lava

Shield volcanoes are almost entirely composed of this kind of very fluid lava?
Of the common types of lava, basaltic lava is the most fluid. However, one volcano, Ol Doinyo Lengai in Africa erupts unique carbonatite lava, which is extremely fluid. This lava appears to be closer in viscosity to water than basaltic lava.
What type of rock makes shield volcanoes?
Shield volcanoes are typically formed from basaltic lava flows, which are low in silica content and very fluid. This type of lava allows for the gradual buildup of wide, gently sloping volcanic cones characteristic of shield volcanoes.
