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.

What type of volcanoes formed the Hawaiian islands?

The Hawaiian islands were formed by shield volcanoes, which are characterized by long, gentle sloping sides formed by low-viscosity lava flows. These volcanoes are created by the movement of the Pacific Plate over a hot spot in the Earth's mantle, resulting in a chain of volcanic islands.


Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?

Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.


Most shield volcanoes have grown from the ocean floor to form?

Most shield volcanoes have grown from the ocean floor to form broad, gently sloping structures with low viscosity lava flows. They are typically formed by multiple eruptions of basaltic lava, which flows easily and spreads out over a wide area, resulting in the characteristic shield shape.


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.


What are the three types of volacanoes?

The three types of volcanoes are shield, cinder cone, and stratovolcano. Shield volcanoes have gentle slopes and are formed by the eruption of low-viscosity lava flows. Cinder cone volcanoes are steep-sided and are formed by the accumulation of loose pyroclastic material around a vent. Stratovolcanoes have a conical shape and are composed of alternating layers of lava flows, volcanic ash, and debris.

Does the composite volcano have high viscosity?

Composite volcanoes typically have higher viscosity lava compared to shield volcanoes, resulting in more explosive eruptions. The high silica content in the magma of composite volcanoes contributes to this higher viscosity. However, the exact viscosity of the lava can vary depending on specific factors such as temperature and gas content.


Are shield volcanoes and volcanoes the same?

No, shield volcanoes are a specific type of volcano characterized by their broad, gentle slopes and low viscosity lava flows. "Volcano" is a general term that refers to any landform where volcanic activity occurs, encompassing a variety of volcano types such as shield, composite, and cinder cone volcanoes.


What kind of rock is found in a shield volcano?

Shield volcanoes are primarily composed of basaltic rock, which is a type of volcanic rock that is low in silica content and high in iron and magnesium. This type of rock creates gently sloping shield volcanoes due to its low viscosity and ability to flow easily during eruptions.


The magma of shield volcanoes is rich in?

The magma of shield volcanoes is rich in basalt. Basalt magma is low in viscosity and gas content, allowing it to flow easily and lead to the broad, gently sloping shape characteristic of shield volcanoes.


What are three types of volcanoes?

Three types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while stratovolcanoes are characterized by alternating layers of lava and ash. Cinder cone volcanoes are small, steep-sided volcanoes formed by pyroclastic material ejected during eruptions.


Are shield volcanoes steep mountains?

No, shield volcanoes are not steep mountains. They have gently sloping sides due to the relatively low viscosity of the lava that flows from them, which allows the lava to spread out and create a wide, shield-like shape.


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.


What type of volcanoes are the hawiian islands?

The Hawaiian Islands are primarily made up of shield volcanoes. These volcanoes have gentle slopes and are formed by repeated eruptions of low-viscosity lava that can flow long distances. The shield volcanoes in Hawaii, such as Mauna Loa and Mauna Kea, are some of the largest in the world.


Are there giant volcanoes on mercury?

Yes, but they are not high mountains but shield volcanoes.

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.


What kind of lava forms shield volcanoes?

Shield volcanoes are fed by basaltic magma.
