No. Basaltic lava has less silica than andesitic lava which makes it less viscous and so basaltic lava flows more easily than andesitic lava.
The amount of viscosity present in magma depends on the amount of silica it has. A composite volcano produces rhyolitic lava which is very thick. A shield volcano produces a basaltic lava with less silica and significantly less viscosity.
Basaltic lava typically has a low gas content compared to other types of lava such as andesitic or rhyolitic. This is because basaltic lava is less viscous, allowing gases to escape more easily, resulting in less gas being trapped within the lava as it erupts.
Basaltic lava is less viscous.
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.
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.

Basaltic lava is less viscous.
Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.

Oceanic volcanoes usually release basaltic lava. Basaltic lava is low in silica content, which makes it less viscous and allows it to flow easily and travel long distances before solidifying. This type of lava is common in underwater volcanic activity due to the melting of basaltic oceanic crust.
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
I'm not sure... but the two different types of lava are: Viscous - sticky and slow moving, resulting in tall volcanoes Non Viscous - runny and fast moving, resulting in short and very spread out volcanoes (shield volcanoes)
Eyjafjallajökull volcano produced a type of lava called basaltic lava. Basaltic lava is low in silica content, which makes it less viscous and allows it to flow more easily over the surface, leading to the formation of shield volcanoes like Eyjafjallajökull.
Mafic lava is low in silica and high in iron and magnesium, which makes it less viscous and more fluid compared to felsic lava. It tends to flow easily and often forms basaltic rocks when it cools. Mafic lava eruptions typically result in gentle, effusive lava flows rather than explosive eruptions.
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
