What else can I help you with?
What is the source of the magma in Hawaii's volcanoes?
Basaltic
Is Lava flowing from volcanoes in Hawaii basaltic magma.?
Yes!
Can you find lots of basaltic volcanoes in Hawaii and Iceland?
Yes, you can actually.
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.
What type of volcano is Rangitoto in Auckland New Zealand?
Basaltic, like Hawaii
Lava flowing from a volcano in Hawaii is basaltic magma?
Lava is erupting in Hawaii as we breathe that is turning into basalt rock.
Where do most rocks have a basaltic composition?
Most rocks with a basaltic composition are typically found in oceanic crust, such as the ocean floors and mid-ocean ridges. Basaltic rocks are also common in volcanic regions like Hawaii and Iceland.
The volcanoes of Hawaii form fron thin basaltic magma that tends to erupt quietly What is one reason for the quiet eruptions?
Basaltic magma allows dissolved gases to bubble upward and escape
What type of rocks are found in Hawaii Volcanoes National Park?
Hawaii Volcanoes National Park is known for having basaltic rocks, including basaltic lava flows, cinders, and ash. These rocks are primarily formed from the eruptions of the shield volcanoes in the park, such as Mauna Loa and Kilauea.
Fluid basaltic lavas like those in hawaii commonly form what?
Fluid basaltic lavas such as rhyolite and dacite typically form thick short lavas namely lava spines, lava domes or coulees.
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.
What type of volcano is Hawaii?
Hawaii has shield volcanoes, which are broad, gently sloping volcanoes characterized by eruptions of relatively fluid lava that creates a wide base. These volcanoes are formed by repeated eruptions of low viscosity basaltic magma.
