No. Mount St Helens would produce block lava flows rather than pahhoehoe or a'a because of the high silica content. Currently there are no lava flows on that volcano but there is a lava dome made primarily of dacite.

What is the difference between pahoehoe and lava?

Pahoehoe is faster moving lava and AA is slower moving lava. Both types are found in basaltic type eruptions. They have different appearances. Pahoehoe is smooth and ropey where as AA is chunky and rough.(much like top of trees) Often a pahoehoe flow can change to an AA flow depending upon the type of slope it encounters. The steeper the slope the more likely AA lava will be present. Aa has more viscosity than Pahoehoe.


What type of lava results in rocks with a ropy texture?

Pahoehoe lava results in rocks with a ropy texture. This type of lava has a smooth, undulating surface due to its low viscosity.


Lava that flows slowly to form a glassy surface with rounded wrinkles is called?

The lava is pahoehoe Lava.


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.


Which type of basaltic lava has a fairly smooth surface that resembles the twisted braids of ropes?

Pahoehoe lava is a type of basaltic lava that has a fairly smooth surface that can resemble twisted braids of ropes. This lava is characterized by its smooth, ropy texture formed as it flows and cools.


Which types of eruptions produce pahoehoe lava?

Pahoehoe lava is typically produced during effusive, non-explosive eruptions that have low viscosity and high temperatures. These types of eruptions are commonly associated with shield volcanoes, where the lava flows smoothly and forms a ropey or wrinkled surface as it cools.

Are basaltic lavas a pahoehoe lava?

Basaltic lavas can be either pahoehoe or a'a lava types. Pahoehoe lavas have smooth, rope-like textures, while a'a lavas are rough and jagged. The type of lava formed depends on various factors such as temperature, composition, and viscosity.
