Why does a constructive plate boundary produce a shield shape and a destructive plate boundary produce a cone shape?
Its to do with the viscosity of the lava, the thicker (more viscous) the lava the slower and less far it will travel making a shield volcano. This happens on a constructive plate boundary. on a destructive plate boundary the lava is less viscous and runs further making a conical shaped volcano

What type of volcano is mountain Eyjafjallajokull?
It is a shield volcano, as it occurs on a divergent pllate boundary (constructive boundary)
What is the formation of shield volcanos?

What kind of boundary do Shield volcanoes form?
hot spots and convergent boundaries
Is Mauna Loa on transform boundary?
No, Mauna Loa is not located on a transform boundary. It is a shield volcano located on the Big Island of Hawaii and is primarily formed by hotspot volcanism, where magma rises from deep within the Earth's mantle.
What are constructive volcanoes?
Constructive volcanoes, also known as shield volcanoes, are characterized by their broad, gently sloping sides and low viscosity lava flows. These volcanoes are typically formed from multiple eruptions of basaltic lava, which spreads out in thin layers to create a gradual and shield-like shape. Constructive volcanoes are associated with effusive eruptions, where lava flows steadily and continuously.
Which of the mountain chains form a boundary with the Canadian shield?
The Appalachian Mountains form a boundary with the Canadian Shield. The Canadian Shield is a large geological formation covering much of eastern and northern Canada, while the Appalachian Mountains run along the eastern coast of North America, from Alabama in the U.S. to Newfoundland in Canada.
What types of eruption does a shield volcano have?
Shield volcanoes usually produce effusive eruptions.
Do shield volcanoes produce quiet or explosive eruptions?
Eruptions at shield volcanoes are almost always non-explosive.
