How are blocky lava and aa lava similar?
Both blocky lava and aa lava are types of viscous, cooler lava flows that form rough, jagged surfaces. They are characterized by their slow movement and blocky appearance due to the solidifying of the lava flow before it fully cools.
What are the three types of lava?
Pahoehoe lava, Aa lava, and Blocky lava
Does Mount St Helens spew pahoehoe pillow Aa or Blocky lava?
Mount St. Helens mainly produces blocky lava (andesitic) during its eruptions. However, the volcano has also had episodes where it spewed pahoehoe lava due to changes in eruptive style.
Why did copahue volcano erupt?
it's is a stratovolcano
What is AAA lava?
Lava that hardens into rough , jagged rocks with a crumbly feeling aka blocky lava
Is shaving gel similar to blocky lava?
Yes
Why is blocky lava an important clue to the explosiveness of volcano?
Blocky lava, known as andesitic or rhyolitic lava, typically indicates a high-viscosity magma that traps gases, leading to explosive eruptions. The angular, jagged formations of blocky lava suggest that the lava cools and solidifies relatively quickly, often in a more viscous state. This behavior contrasts with fluid basaltic lava, which tends to flow smoothly and produce less explosive eruptions. Therefore, the presence of blocky lava can signal a volcano's potential for more violent eruptive activity.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
What is the geology term AAA?
Aa is a term for a blocky type of lava.
Is mount Krakatoa a shield volcano?
No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.
Why is blocky lava an important clue to the explosiveness of a volcano?
Blocky lava, also known as aa lava, is characterized by its rough, jagged surface and indicates a higher viscosity in the magma. This increased viscosity can trap gases, leading to greater pressure buildup within the volcano. When the pressure is eventually released, it can result in explosive eruptions. Therefore, the presence of blocky lava suggests a greater potential for explosive volcanic activity compared to more fluid lava types.
When volcano erupt they expel what zircons or lava?
lava
