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.
Why would felsic lava not produce a natural tunnel within itself as it cools?
Lava tubes formed from mafic lava form when the lava forms a crust over itself, creating a tube through which it can flow and later leave empty. Felsic lava forms a crust, but is too viscous to entirely flow out of it.
What type of lava does Arenal have?
Arenal Volcano in Costa Rica mainly produces basaltic andesite lava. This type of lava is characterized by its intermediate silica content, which results in a thick, slow-moving lava flow.
What is the smooth lava flow called?
The smooth and shiny lava is called pahoehoe.
How do lava tubes caves formed?
Lava tubs form as a result of pahoehoe lava flows. As one of these flows progresses, it builds of a layer of rock on top of it. eventually, thus becomes thick enough to support is own weight, and forms an insulating tube through which lava can flow.

How many types of lava flow?
2. Thick or runny lava. Thick flows slowly, runny flows faster.

Which is a rounded volcanic feature that forms when a mass of thick lava slowly erupts from the vent?
This is called a lava dome.

What is the name of the volcano that is built by thick layer of lava?
A shield volcano. Generally they have runny lava that forms lots of thick layers. The Hawaiian island volcanos are good examples.
Area of rock that flows like a thick liquid?
The area of rock that flows like a thick liquid is called lava. Lava is molten rock that erupts from a volcano and can flow slowly downhill, resembling the movement of a thick liquid.
Lava that forms smooth ropelike coils when it hardens is called?
Pahoehoe
Which features may occur when volcano lava cools at the surface?
Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.
