Want this question answered?
Silica.
flows easily
magma that is low in silica and flows easily
no
magma that is low on silica & thin and runny & it flows easily
This characteristic is called viscosity.
Yes. The same is true of any liquid.
magma that is low on silica & thin and runny & it flows easily
could be physical boundaries or open water sources or maybe pits. Even the air pressure that built up under it can help push itThe 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.
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 always flows.
