Is pahoehoe lava only found in Hawaii?

No. Many shield volcanoes produces pahoehoe.

Do shield volcanoes have pahoehoe lava?

Not always. Shield volcanoes produce basaltic lava, which can form into either pahoehoe or a'a. Sometimes both are found in the same lava flow.

How does pahoehoe form?

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 are two types of volcanoes?

composite volcanoes and 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 three kinds of volcanoes?

. Shield Volcanoes, Cinder Cone volcanoes, and Composite Volcanoes .

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 stravolcanos cinder shield or composite volcano?

Stratovolcanoes are composite volcanoes.

How are shield volcanoes and composite volcanoes alike?

Both shield and cinder cone volcanoes primarily erupt basaltic lava.

Compare shield volcanoes to composite volcanoes?

composite and sheild volcanoes are both formed by lava flows and their hights are in the thousands.

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.
