What else can I help you with?
Does the lava that forms shield volcanoes probably have a lot of silica or water in it?
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
What kind of lava forms shield volcanoes?
Shield volcanoes are fed by basaltic magma.
Do shield volcanoes have high silica content in the lava?
No, shield volcanoes typically have low silica content in their lava, which results in fluid-like, runny eruptions. This low silica content allows for the lava to flow easily and create the wide, gentle slopes characteristic of shield volcanoes.
What is the lava of cinder cone volcanoes?
A cinder cone has basaltic lava, which has a fairly low viscosity.
Are hawaiian volcanoes low or high in viscosity?
Hawaiian volcanoes are typically low in viscosity, meaning they have a relatively fluid lava composition compared to other types of volcanoes. This low viscosity allows the lava to flow more easily, resulting in gentle eruptions characterized by flowing lava streams rather than explosive eruptions.
Do shield volcanoes have high viscosity?
No, shield volcanoes have low viscosity lava due to their composition of basaltic magma, which has low silica content. This low viscosity allows the lava to flow easily and spread out over a wide area, resulting in the gentle, sloping shape characteristic of shield volcanoes.
Shield volcanoes are almost entirely composed of this kind of very fluid lava.?
Basaltic lava (low in silica).
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
Can lava make volcanoes?
NO, volcanoes make lava.
What type of volcanoes make up the Hawaiian islands and why is it easy to determine?
Shield volcanoes make up the Hawaiian islands. These volcanoes have low, broad profiles and are typically formed by the eruption of low-viscosity basaltic lava. It is easy to determine the type of volcanoes because of their distinctive shape and the lava flows they produce.
Are hawaiian islands spatter cones?
No, they're shield volcanoes. The lava in spatter cones is highly viscous whereas the lava that forms shield volcanoes (that you can see flowing in Hawaii) has a very low viscosity. Shield volcanoes are low profile, broad lumps; these are the Hawaiian islands.
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.
