What else can I help you with?
Is Mt Erebus an active volcano?
It is a lava flow, and has an AA (ah-ah) lava flow
What features may occur when volcano lava cools at the surface?
When volcano lava cools at the surface, it may form different features such as lava rock formations like basalt columns, lava tubes, and aa or pahoehoe lava flows. These features depend on the cooling rate and composition of the lava.
Does the cotopaxi volcano have AA or Pahoiehoie lava?
Both.
What types of lava come from the San Cristobal volcano?
The San Cristobal volcano in Nicaragua primarily produces basaltic lava, which is low in silica content and flows easily. This type of lava typically results in effusive eruptions with lava flows that can travel long distances from the volcano. The lava from the San Cristobal volcano tends to be relatively fluid and forms shield volcanoes.
What is the Rock type of mount stromboli?
A Stratovolcano Composite Volcano with aa lava

Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.
What is the Rock type of mount stromboli?
A Stratovolcano Composite Volcano with aa lava
What lava does a shield volcano erupt poehoehoe or AA?
Usually both.
What kind of rock forms when lava cools?
Either a type of lava called AA (ah-ah) comes out of the volcano of a type of lava called pahoho comes out.An Extrusive Igneous Rock.
Is Kilauea Volcano pahoehoe or AA?
Kilauea Volcano primarily produces pahoehoe lava, which is characterized by its smooth, ropy surface. However, during more explosive eruptions or when the lava cools and thickens, it can also produce aa lava, which is rough and jagged. The type of lava depends on various factors, including temperature and gas content. Overall, pahoehoe is more commonly associated with Kilauea's eruptions.
What kind of lava does Haleakala have?
it has aa lava, so it is not fluid like, but still basaltic.
What type of lava is erupted from Mount Kilimanjaro?
Mt. Fuji is Japan's highest mountain. The lava that comes out of this volcano is silica-poor lava that is very thick and chunky.
Is a composite volcano made of Aa lava?
No. If a'a is present it will usually be only a minor portion of the volcano. A'a and pahoehoe are low-viscosity lavas with a low silica content They are usually found in shield volcanoes. A composite volcano is usually primarily composed of composed of tepha (loose ash, pumice, and lapilli), tuff (welded ash), and block lava (very viscous lava flows). This material is usually more viscous with more silica than what goes into a'a and pahoehoe.
