What do fluid basaltic lavas commonly form?
Pahoehoe Flows.
Fluid basaltic lavas commonly form?
Fluid basaltic lavas commonly form from low-viscosity magma with high temperatures and low silica content. When erupted, these lavas tend to flow long distances and form thin, low-angle lava flows that can extend for many kilometers before solidifying. Basaltic lavas are common at hot spot volcanoes, mid-ocean ridges, and shield volcanoes.
What are types of rocks and minerals found in the island of Hawaii?
Hawaii is formed primarily of basaltic rocks, including basalt and other volcanic rocks. Minerals commonly found in these rocks include olivine, feldspar, and pyroxene. The unique geology of Hawaii also gives rise to minerals such as peridot, a gemstone found in basaltic lava rocks.
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.
Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are generally hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which makes them flow more easily. Andesite lavas, on the other hand, have higher silica content, making them cooler and more viscous.

How do rhyolitic magma or lava and basaltic lava differ?
rhyolitic mama is associated with explosive volcanism and is ejected (blown out of) a volcano rapidly. Basaltic lavas are released during effusive volcanism that is not explosive, such as hawaii where the lave "flows" into the ocean slowly. Basaltic lavas have a lower silica content as well.
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.
Where do rocks have a basaltic composition?
Oceanic crust is made of basaltic rock. The rocks formed from hotspot volcano lavas are also often basaltic too.
What type of lava comes from what volcano?
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
Which is volcanic lava rock basaltic or granitic?
The most common type of lava is basaltic. However some lavas may be andesitic or ryolitic. Rhyolite is the extrustive equivalent of granite.
