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.
Name the two types of lava?
The two main types of lava are pahoehoe, which has a smooth, rope-like texture, and aa, which has a rough, jagged texture. They differ in their viscosity and flow characteristics, with pahoehoe being more fluid and aa being more viscous.
What type of lava does Mount Rainier have Aa or Pahoehoe?
Mount Rainier primarily has andesitic lava, which can exhibit characteristics of both Aa and Pahoehoe types. However, the predominant lava flows associated with Mount Rainier are typically more akin to Aa, as they are often cooler and more viscous, resulting in a rough, jagged surface. Pahoehoe, which is smoother and more fluid, can occur but is less common in this region.
What type of lava is thick stiff and does not flow easily?
Thick, stiff lava that does not flow easily is known as aa lava. Aa lava has a rough, blocky texture due to its high viscosity, making it difficult for the lava to flow smoothly. Aa lava typically moves in a jerky, slow manner and can form sharp, jagged edges as it solidifies.
Does Mount Kilimanjaro errupt pahoehoe or AA lava?
Mount Kilimanjaro is a dormant stratovolcano primarily composed of volcanic rock and does not erupt lava in the same manner as active volcanoes. It is primarily characterized by its volcanic materials rather than specific lava types like pahoehoe or aa. However, its past eruptions, which occurred thousands of years ago, produced both types of lava; pahoehoe is known for its smooth, ropy surface, while aa is rough and jagged. Overall, Kilimanjaro's volcanic history includes a variety of lava flows, but it is not currently an active erupting volcano.

What is the difference between pahoehoe and AA lava?
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
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.
What are the three types of lava?
Pahoehoe lava, Aa lava, and Blocky lava

Is aa lava explosive lava?
No. A lava flow usually indicates an eruption that is not explosive.
Does mt st Helens have pahoehoe or AA lava?
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
What does AA mean in terms of Earth Science?
AA: jagged chunks of lava formed by rapid cooling on the surface of a lava flow
