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.
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.
Which volcanoes are Massive gently sloping volcanoes built of successive basaltic lava flows?
Massive gently sloping volcanoes built of successive basaltic lava flows are called shield volcanoes. Examples of shield volcanoes include Mauna Loa in Hawaii and Mount Etna in Italy. These volcanoes are characterized by their broad, low-profile shape and the relatively peaceful eruptions of fluid lava.
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
Which types of lava eruptions cover the largest area on Eath's surface?
shield volcanoes

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.

Which types of lava eruptions cover the largest area on Eath's surface?
shield volcanoes
Submerged basaltic volcanoes that are higher than 1 km are called?
Basalt volcanoes are referred to as shield volcanoes. Volcanoes of this type include Mauna Loa and Kilauea, both in Hawaii.
Why are volcanoes in Hawaii the least severe?
The volcanoes in Hawaii erupt basaltic lava, which is relatively runny and has a low gas content. As a result the volcanoes usually produce effusive eruptions; fountain or oozing lava but rarely producing explosions. After emerging the lava travels along as fairly slow-moving lava flows. These flows can be destructive, but are easy to escape.
Describe one benefit of volcanoes and one danger volcanoes pose?
they create new land. For example Hawaii. The eruptions can cause tsunamis
Which volcanoes have only nonexplosive eruptions?
Some volcanoes known for having only nonexplosive eruptions include Kilauea in Hawaii and Piton de la Fournaise in Reunion Island. These eruptions typically involve the lava flowing steadily rather than explosive ash clouds.
