Individual volcanoes vary in the volcanic materials they produce, and this affects the size, shape, and structure of the volcano. There are three types of volcanoes:
cinder cones (also called spatter cones), composite volcanoes (also called stratovolcanoes), and shield volcanoes
.

What are the 3 types of volcanoes describe the differences between each type?
There are three main types of volcano –
composite or strato, shield and dome
. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. … When composite volcanoes erupt they are explosive and pose a threat to nearby life and property.
What are the 7 types of volcano?
The result is the classic cone shape of composite volcanoes. A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow,
(7) vent, (8) lava, (9) ash cloud
.
What is the largest volcano type?
Mauna Kea and Mauna Loa are
shield volcanoes
. They are the world's largest active volcanoes, rising over 9 km above the sea floor around the island of Hawai'i.
What volcano could destroy the world?
The Yellowstone supervolcano
is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.
What is the most powerful volcano on Earth?
The explosion of
Mount Tambora
is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
What is the deadliest volcano of all time?

What shape is a shield volcano?
Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building
a broad, gently sloping cone of flat, domical shape
, with a profile much like that of a warrior's shield.

What is the difference between magma and lava?
Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. … This magma can push through holes or cracks in the crust, causing a
volcanic eruption
. When magma flows or erupts onto Earth's surface, it is called lava. Like solid rock, magma is a mixture of minerals.
What is the oldest volcano?
How old is the oldest volcano? The oldest volcano is probably
Etna
and that is about 350,000 years old. Most of the active volcanoes that we know about seem to be less than 100,000 years old.
How many craters does Taal volcano have?
The island consists of different overlapping cones and craters, of which
forty-seven
have been identified. Twenty six of these are tuff cones, five are cinder cones, and four are maars.
Is Yellowstone volcano the largest in the world?
Yellowstone is one of the largest known volcanoes in the world and the
largest volcanic system in North America
. Yellowstone is also the world's largest hydrothermal system. …
How many Super volcanoes are on earth?
There are about
12 supervolcanoes
on Earth — each one at least seven times larger than Mount Tambora, which had the biggest eruption in recorded history. If all of these supervolcanoes erupted at once, they'd likely pour thousands of tons of volcanic ash and toxic gases into the atmosphere.
Is Yellowstone due to erupt?
But at some point,
Yellowstone is going to erupt
. It has erupted before and it will erupt again. Scientists have been studying the Supervolcano at Yellowstone for a long time, and piecing the studies together gives us a glimpse of what things will be like next time Yellowstone erupts.
