could be physical boundaries or open water sources or maybe pits. Even the air pressure that built up under it can help push it
The ease of magma flow is known as the Viscosity, which is a measure of fluid a substance is. The viscosity of magma will be due to many factors including; the rock type in the volcano, and the temperature of the magma.

Magma flows easily when it is low in?
Silica.
Is it true how easily magma flows depends on its visocisty?
Yes. The same is true of any liquid.
Which type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
How does the viscosity of the magma influence the type of eruption?
The viscosity of magma affects whether or not magma flows away or piles up during an eruption. Viscosity, along with volatiles (dissolved gases) and volume determine whether you have a peaceful eruption or a very violent one.
Magma flows in the mantle like a river and can form magma pools?
true
Magma flows easily when it is low in?
Silica.
Which is not a characteristic of magma from an explosive eruption?
flows easily
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily
Is flows easily a physical property of magma from a explosive eruption?
no
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
What are three things that determine how fast lava flows?
Viscousity, Pressure, and Chemical composition of the magma.
Is it true how easily magma flows depends on its visocisty?
Yes. The same is true of any liquid.
Which type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
What is a constructive boundarie?
At a constructive plate boundary two plates move apart. As they move apart the magma from the magma chamber flows up to fill the gap. This causes a volcano. However, as the magma can escape easily it flows down the volcano with only a little bit of force. So it has a gentle erupt.
Magma may flow or it can?
Magma always flows.
