Are pahoehoe and AA produced during explosive eruptions?
No, pahoehoe and aa lava are typically produced during non-explosive eruptions. Pahoehoe lava has a smooth, ropey texture, while aa lava is rough and jagged. Explosive eruptions typically produce ash, pyroclastic flows, and lava domes.
What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruptions that occurred?
Lava flows of pahoehoe and aa indicate that the eruption was effusive ("quiet") rather than explosive, or only very mildly explosive.
What do lava flows the made of pahoehoe and AA Indicate about the type of volcanic eruption that occurred?
Lava flows of pahoehoe and aa indicate that the eruption was effusive ("quiet") rather than explosive, or only very mildly explosive.
What do lava flows made of pahoehoe and AA indicate about the the type of volcanic eruptions and occurred?
Lava flows of pahoehoe and aa indicate that the eruption was effusive ("quiet") rather than explosive, or only very mildly explosive.
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 do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption that occured?
They indicate that an eruption is effusive rather than explosive.
What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption the occured?
They indicate that an eruption is effusive rather than explosive.
When a common type of basaltic lava hardens it forms AA which has?
When basaltic lava hardens into AA lava, it forms a rough, jagged surface characterized by sharp, angular blocks and spiny projections. This texture results from the higher viscosity of the lava, which cools and solidifies before it can flow smoothly. AA lava typically has a lower gas content compared to Pāhoehoe lava, leading to its more fragmented appearance. Its formation often occurs during more explosive eruptions or in scenarios where the lava is relatively cooler.
What are the three types of lava?
Pahoehoe lava, Aa lava, and Blocky lava
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.
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 type of material do explosive volcanoes produce?
An explosive eruption is caused by magma with a high content of water and silica. Non-explosive eruptions are caused by either lava because it is a thicker consistency, or magma with a low content of water and silica.
