because more pressure builds up inside of stravovolcanoes ,causing powerful eruptions

Eruptions of stratovolcanoes are typically more destructive than cinder cone volcanoes because stratovolcanoes have more explosive eruptions. This is because stratovolcanoes are built up over time by layers of viscous lava and pyroclastic materials, which can trap gas pockets. When the pressure builds up, it can lead to explosive eruptions that release a vast amount of ash, gas, and pyroclastic flows, causing widespread destruction and hazards. In contrast, cinder cone volcanoes typically have more effusive eruptions with less explosive activity.

Why are the eruptions of stratovolcanoes usually more destructive than the eruptions of cinder cone volcanoes?
Cindercone volcanoes erupt relative small amounts of magma, compared with stratovolcanoes, which not only hold more magma, but often more viscous magma with a higher gas content. This means eruptions tend to be larger and more explosive. As a result, cinder cones primarily erupt fountains of lava while stratovolcanoes tend to erupt massive ash clouds and pyroclastic flows.
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
Which type of the volcano gives pyroclastic debris?
Pyroclastic debris is usually produced by stratovolcanoes. However, shield volcanoes occasionally produce pryoclastic material in phreatomagmatic eruptions, which involve water interacting with magma.
Which is the most destructive a strombolian or a plinian?
Plinian eruptions are the most destructive. Strombolian eruptions are usually fairly small.

Is a Stratovolcano an explosive volcano?
Yes. Stratovolcanoes usually alternate between explosive and non-explosive eruptions.
What types of eruption does a shield volcano have?
Shield volcanoes usually produce effusive eruptions.
Why are volcanoes in Hawaii the least severe?
The volcanoes in Hawaii erupt basaltic lava, which is relatively runny and has a low gas content. As a result the volcanoes usually produce effusive eruptions; fountain or oozing lava but rarely producing explosions. After emerging the lava travels along as fairly slow-moving lava flows. These flows can be destructive, but are easy to escape.
Are all volcanoes the same or are there different kinds of volcanoes?
There are indeed different types of volcano, and even among these, no two volcanoes are exactly alike. For most intents and purposes there are three main types of volcano. Shield volcanoes are large, with broad, gentle slopes made of cooled lava flows. These volcanoes usually fountain or ooze lava, rarely erupting in an explosive manner. The volcanoes of Hawaii and shield volcanoes. Cinder cones are repetitively small and steep-sided, made primarily of cooled chunks of lava called scoria that were ejected into the air. Such volcanoes usually erupt in a somewhat explosive manner. Notable cincer cones include Sunset Crater and Paricutin. Stratovolcanoes, also called composite, are generally quite tall with steep slopes composed of layers of lava flows, cinders, and ash. Stratovolcanoes are highly variable in how they erupt. Sometimes they gently ooze lava, but they are best know for their large, explosive eruptions of ash and pumice. Notable stratovolcanoes include Mount St. Helens and Mount Vesuvius.
Do dormant volcanoes wear away?
It is called erosion and it acts on everything including active volcanoes. However active volcanoes can usually rebuild with more eruptions faster than they erode.
What types of lava will most likely lead to a volcanic eruption of an effusive nature?
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
How do volcanoes affect the Earth's system?
When volcanoes erupt, usually land is destroyed AND constructed. These eruptions occur due to the pushing in, pulling apart or sliding of the tectonic plates under the earth's crust. This movement builds up pressure and causes eruptions.
