Composite volcanoes
are also called stratovolcanoes. This is because they are formed by alternating layers (strata) of magma and ash (Figure below). The magma that creates composite volcanoes tends to be thick. The steep sides form because the lava cannot flow too far from the vent.
Which type of volcano builds up with layers of lava rock and ash like a layer cake )?
Stratovolcano – Also known as a composite volcano
, is a conical volcano built up by many layers (strata) of hardened lava, tephra, pumice, and volcanic ash.
Which layers of lava alternate with layers of ash are called?
Composite volcanoes
are tall, cone-shaped mountains in which layers of lava alternate with layers of ash. Dome mountains forms when a mass of hardened magma is uplifted, causing the layers of rock to bend upward.
Which of the following is made of layers of ash and lava?
Major Types of Volcanic Cones
Also known as stratocones,
composite cones
are made up of layers of lava, volcanic ash, and fragmented rocks. These layers are built up over time as the volcano erupts through a vent or group of vents at the summit's crater.
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 are the 3 types of volcano?
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 4 primary types of volcanoes?
Geologists usually group volcanoes into four main types:
cinder cones, composite volcanoes, shield volcanoes, and lava domes
.
What are the 11 types of volcanoes?
- Cinder Cone Volcanoes: These are the simplest type of volcano. …
- Composite Volcanoes: Composite volcanoes, or stratovolcanoes make up some of the world's most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example. …
- Shield Volcanoes: …
- Lava Domes:
Which type of volcano is the most explosive?
Because they form in a system of underground conduits,
stratovolcanoes
may blow out the sides of the cone as well as the summit crater. Stratovolcanoes are considered the most violent.
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 type of lava erupts from a shield volcano?
Shield volcanoes are almost exclusively
basalt
, a type of lava that is very fluid when erupted.
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.
Which is not a major type of volcano?
Which of these is not a major type of volcano?
Mount Rainier
.
