Stratovolcanoes have relatively steep sides and are
more cone-shaped than shield volcanoes
. … The lava therefore builds up around the vent forming a volcano with steep sides. Stratovolcanoes are more likely to produce explosive eruptions due to gas building up in the viscous magma.
What are 3 shield volcanoes?
Examples of shield volcanoes are
Kilauea and Mauna Loa
(and their Hawaiian friends), Fernandina (and its Galápagos friends), Karthala, Erta Ale, Tolbachik, Masaya, and many others. Here are 4 of the volcanoes that comprise the big island of Hawai'i. They are Mauna Kea (MK), Mauna Loa (ML), Hualalai (H), and Kohala (K).
What type of eruption is a stratovolcano?
The eruptive history of most stratovolcanoes is delineated by
highly explosive Plinian eruptions
. These dangerous eruptions are often associated with deadly pyroclastic flows composed of hot volcanic fragments and toxic gases that advance down slopes at hurricane-force speeds.
What are known as shield volcanoes?
A shield volcano is a
wide volcano with shallowly-sloping sides
. Shield volcanoes are formed by lava flows of low viscosity – lava that flows easily. … The largest is Mauna Loa on the Big Island of Hawaii; all the volcanoes in the Hawaiian Islands are shield volcanoes.

What is largest volcano on Earth?
Rising gradually to more than 4 km (2.5 mi) above sea level,
Hawaii's Mauna Loa
is the largest active volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km (5 mi).
What is the difference between a stratovolcano and a shield volcano?
That's because the viscous volcanic material doesn't flow that far from where it is erupted, so it builds up in layers forming a cone-shaped volcano known as a stratovolcano. Shield volcanoes, on the other hand, have gentle slopes that are
less than 10°
and erupt more fluid lavas called basalt.

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 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.
Is Taal Volcano a supervolcano?
