Thick, sticky, high-silica magma are so viscous that they don't erupt, causing internal pressure within a volcano to rise. Earth's crust fails under high pressure, explosion eruption.
Runny, low silica, high temperature basaltic lava are so low in viscosity that they erupt quite easily and produce quiet eruptions of freely flowing lava.
What else can I help you with?
Do all volcanoes have the same characteristics?
No, not all volcanoes have the same characteristics. Volcanoes can vary in size, shape, eruption style, composition of erupted materials, and frequency of eruptions. Some volcanoes are steep-sided and explosive, while others are gently sloping and effusive.
What type of vocanoes are there?
There are four main types of volcanoes: shield volcanoes, cinder cone volcanoes, stratovolcanoes (composite volcanoes), and calderas. Each type has distinct characteristics based on their eruption style, shape, and composition.
How many different shapes of volcanoes are there?
There are three main shapes of volcanoes: shield volcanoes, cinder cone volcanoes, and stratovolcanoes. Each type has distinct characteristics based on its eruption style, lava composition, and shape.
What do you call mountains hills and volcanoes?
Mountains, hills, and volcanoes are all types of landforms that rise prominently above the surrounding terrain. Collectively, they can be referred to as "topographical features" or "elevated landforms." Each type has distinct characteristics: mountains are generally steeper and higher, hills are lower and more gently sloping, while volcanoes are formed by volcanic activity and can vary widely in shape and size.
What are the names of the different types of volcano formations?
The main types of volcano formations are shield volcanoes, stratovolcanoes (composite volcanoes), cinder cone volcanoes, and calderas. Each type has distinct characteristics based on their eruption style and the type of materials they release.

What type of vocanoes are there?
There are four main types of volcanoes: shield volcanoes, cinder cone volcanoes, stratovolcanoes (composite volcanoes), and calderas. Each type has distinct characteristics based on their eruption style, shape, and composition.
What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.

What are the 3 types of valcanoes?
There are four basic types of volcanos. They are cinder cones, shield volcanoes, composite volcanoes, and lava domes. Composite volcanoes share some characteristics of all the others.
How do volcanoes differ?
Volcanoes differ in terms of their eruption style, which can vary from explosive eruptions with ash clouds and pyroclastic flows to effusive eruptions with lava flows. They also differ in shape and size, ranging from stratovolcanoes with steep slopes to shield volcanoes with gentle slopes. Additionally, the type of magma they erupt, such as basaltic, andesitic, or rhyolitic, can vary among volcanoes.
What volcano is the weakest in the world?
It is difficult to determine the weakest volcano in the world as each volcano has its own unique characteristics. Volcanic activity can vary greatly, with some volcanoes being dormant for centuries while others are active more frequently. Some smaller or less known volcanoes may be considered weaker compared to more well-known and active ones.
How many volcanoes have erupted in the last year?
On average, around 50-70 volcanoes erupt each year. However, the number can vary from year to year.
How long does it take to climb a volcano?
The time it takes to climb a volcano can vary depending on factors like the size of the volcano, its elevation, and the individual's fitness level. Climbing smaller volcanoes may take a few hours, while larger and more challenging volcanoes could take a full day or even multiple days to summit.
What are ten characteristics that vary in human populations?
