Types of volcanoes

Answer 1

Shield Volcanoes:

• Large base area
• Gentle slope
• Contains basic lava
• Frequent eruptions
• Quiet and gentle eruptions
• Very tall in height due to large base area

Composite Volcanoes:

• Relatively small base area
• Concave slope
• Contains acidic lava
• Violent eruptions
• Repeated eruptions
• Erupts from the side cones
• Usually not very tall in height due to gentle slopes

Acid-lava Volcanoes

• Small base area
• Steep slope
• Contains acidic lava
• Violent eruptions
• Creates crater lakes (caldera) after eruptions
• Tall in height due to steep slopes

Cinder Cones

• Small base area
• Steep slopes
• Symmetrical slopes
• Moderate eruptions
• Not tall in height as slopes are easily eroded

Answer 2

There are 3 types of volcanoes, shield volcanoes, cinder cone volcanoes, and composite volcanoes.

Shield Volcano- Shield Volcanoes are made mostly of fluid lava flows. Flow after flow pours from a central summit vent. It builds up and turns into what looks like a warriors shield. Some of the largest volcanoes in the world are shield volcanoes. Some have diameters of 3-4 Miles and are 1,500 to 2,000 feet high. The Hawaiian islands are composed of chains of shield volcanoes.

Cinder Cone Volcano- Cinder cones are the simplest kind of volcanoes. Cinder cone volcanoes have a bowl shaped crater and barely ever rise over one thousand feet. When cinder cone volcanoes erupt lava blows furiously into the air and breaks up into small pieces called cinders. There are many cinder cone volcanoes in western North America.

Composite Volcano- Some of the world's biggest mountains are Composite volcanoes. Some people call composite volcanoes stratovolcanoes. Most composite volcanoes have a crater at the top, with a central vent or a group of vents where lava comes out.

Answer 3

There are three main types of volcanoes: shield volcanoes, stratovolcanoes (or composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are usually built from low viscosity lava flows. Stratovolcanoes are steeper and consist of alternating layers of lava flows and ash deposits. Cinder cone volcanoes have steep sides and are built from pyroclastic material.

Answer 4

The 3 major types of volcanoes are Cinder cone, Composite, and Sheild.
