Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?

Aa and pahoehoe lavas are both basaltic in composition. The lava from composite volcanoes is likely to be granitic.

What is Pahoehoe used for?
Pahoehoe lava forms by small pieces of lava from an irregular flow. It is typical in certain types of volcanoes such as shield volcanoes.
What type of volcanoes formed the Hawaiian islands?
The Hawiian islands are formed by shield volcanoes.
What is the difference between shield volcano and composite volcanoes?
A shield volcano is made from lava flows that flow far, making a very wide, not very steep mountain. A cinder cone volcano is the most common type of volcano. It is formed from volcanic fragments and is very steep sided, although not always extremely tall. They usually have just one main vent, and can also sometimes form from a vent of a larger volcano, growing and becoming a whole new volcano. Composite volcanoes resemble very large cinder cone volcanoes at first, but have bigger particles making them up usually and also have multiple vents more often. They also are potentially more explosive.
Do shield volcanoes have high viscosity?
No. Shield volcanoes are fed by low-viscosity basaltic magma.
Was the Eyjafjallajokull Volcano shield or composite?
a composite
Is pahoehoe lava only found in Hawaii?
No. Many shield volcanoes produces pahoehoe.
What are three types of volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
What 2 types of volcanoes are there?
There are three. From smallest to largest, they are: Cinder Cones, Composite Volcanoes (also called Strata Volcanoes), and then Shield Volcanoes.
Why would pahoehoe and a'a lava erupt from shield volcanoes?
Pahoehoe and a'a are textural variaties of basaltic lava, which has a low viscosity, meaning it flows fairly easily. This is the reason for the gentle slopes of shield volcanoes.
What are the 3types of volcanoes?
Cinder cone, stratovolcano, shield volcano
How Compare shield volcanoes and composite volcanoes?
Shield Volcanoes - Wide base found at constructive plate margins Composite Volcanoes - Steeper Sides found at Destructive (subduction) margins
What is the difference between a composite and shield a Volcano?
Shield Volcanoes erupt less violently and flows further then composite volcanoes. A composite volcano erupts more violently.
Are shield volcanoes tall?
No. Compared to composite and cinder cone volcanoes, shield volcanoes are very short. Mauna Loa in Hawaii is a shield volcano.
What are the three types of volocanoes?
Shield Volcanoes, Cinder Cone volcanoes, and Composite Volcanoes.
What are all kinds of volcanoes?
The main types of volcanoes are cinder cone, shield, and composite volcanoes. there are also big,little, and meideium ones
What are three types volcanoes?
Three types of volcanoes are Cinder Cone Volcanoes, Shield Volcanoes and Composite Volcanoes.
What type of volcano is typically the tallest?
Cone volcanoes are typically the tallest and largest. The two other types of volcanoes are shield volcanoes and composite volcanoes.
