What is the characterization of lava flows and cinders?
They are characterized by a conical shape, with steep sides. They rarely reach heights over 1000 ft. They typically have a single, large, central vent at the summit. They are composed almost exclusively of fragmented pyroclastic material, called tephra.
What are the characteristics of each type of volcano?
Types of volcano – composite and shield
- Acidic lava, which is very viscous (sticky).
- Steep sides as the lava doesn’t flow very far before it solidifies.
- Alternate layers of ash and lava. For this reason, they’re also known as stratovolcanoes . Strato means layers.
- Violent eruptions.
- Longer periods between eruptions.
How can you describe the characteristics of cinder cone composite and shield volcano?
Composite volcanoes are tall, steep cones that produce explosive eruptions. Shield volcanoes form very large, gently sloped mounds from effusive eruptions. Cinder cones are the smallest volcanoes and result from accumulation of many small fragments of ejected material.

What is the largest type of volcano?

What is the most dangerous type of eruption?
Composite volcanoes are some of the most dangerous volcanoes on the planet. They tend to occur along oceanic-to-oceanic or oceanic-to-continental boundaries because of subduction zones. They tend to be made of felsic to intermediate rock and the viscosity of the lava means that eruptions tend to be explosive.
What are the 3 types of volcano?
There are three types of volcanoes: cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes. Figure 11.22 illustrates the size and shape differences amongst these volcanoes. Shield volcanoes, which get their name from their broad rounded shape, are the largest.
What is the most powerful volcano on Earth?

What volcano could destroy the world?
