Why do shield volcanoes have steep sides but are still very tall?
shield volcanoes have gentle sides and aren't very tall
What type of rock makes shield volcanoes?
Shield volcanoes are typically formed from basaltic lava flows, which are low in silica content and very fluid. This type of lava allows for the gradual buildup of wide, gently sloping volcanic cones characteristic of shield volcanoes.
What is the typical shape of a shield volcano?
A shield volcano typically has a broad, gently sloping dome shape with a large base and low profile. This shape is formed by numerous eruptions of low-viscosity basaltic lava that flow easily over long distances, building up the volcano gradually over time. The Hawaiian Islands are good examples of shield volcanoes.
Does highly liquid lava form wide shield like mountains?
Yes, highly liquid lava can form wide shield-like mountains called shield volcanoes. These volcanoes have gentle slopes due to the runny nature of the lava which allows it to flow long distances before solidifying. Shield volcanoes are typically found at divergent plate boundaries and hot spots.
What is the name of a low wide based volcano?
A low, wide-based volcano is called a shield volcano. These types of volcanoes have gentle slopes and are formed by the gradual flow of low-viscosity lava. Examples include Mauna Loa in Hawaii and Iceland's shield volcanoes.
Why do shield volcanoes have steep sides but are still very tall?
shield volcanoes have gentle sides and aren't very tall
Are shield volcanoes tall?
No. Compared to composite and cinder cone volcanoes, shield volcanoes are very short. Mauna Loa in Hawaii is a shield volcano.
How do shield volcanoes have wide bases?
Shield volcanoes are wide because they are made to function as an island, much to the surprise of many scientists. These volcanoes are enormously big, usually spreading out over 300 miles.
How Compare shield volcanoes and composite volcanoes?
Shield Volcanoes - Wide base found at constructive plate margins Composite Volcanoes - Steeper Sides found at Destructive (subduction) margins

How are shield volcanoes different from what is usually thought of as a volcano?
Shield volcanoes are different from the commonly imagined volcano because they have a broad, gently sloping shape resembling a shield rather than a tall, conical shape. They are formed by the eruption of low-viscosity lava that flows easily over long distances, creating the shield-like shape. This type of volcano typically has less explosive eruptions and is associated with more effusive, continuous lava flows.
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.
