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 are the characteristics of divergent-boundary volcanoes and convergent boundary volcanoes?
Earthquakes, Formation Of New Crust and Volcanism
How long does it take to climb a volcano?
It would vary, as volcanoes vary considerably in size and difficulty to climb.
Do composite cone volcanoes have mafic lava?
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
What high mountain ranges without volcanoes are built at which type of plate boundary?
High mountain ranges without volcanoes are built at convergent continental plate boundaries. These vary greatly from divergent boundaries which cause volcanoes to form.
Do composite volcanoes have high or low silica?
Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
What are the characteristics of inactive volcanoes?

What are the characteristics of magma associated with shield volcanoes?
Basaltic, runny magma.
How long does it take to climb a volcano?
It would vary, as volcanoes vary considerably in size and difficulty to climb.
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.
What are ten characteristics that vary in human populations?

What are the defining technical components and characteristics of an enterprise system?
Defining technical component and characteristics of an enterprise system vary. They do include, however, software applications that also vary. This is my best answer.

Composite volcanoes are often associated with moderate to high silica contestant, though in reality, the magma composition will vary over time.
What differences do you see in the myths that surround volcanoes?
The myths that surround volcanoes vary by culture, but they have more things in common than they do differences. Volcanoes are often said to be the home of various gods and goddesses, and eruptions occur when the resident gods get angry.
What are the characteristics of a rift valley?
Igneous. Crustal material is added in rift valleys by the addition of magma.
