An igneous rock with a low silica content that flows easily?
No igneous rock flows easily. However, basaltic lava can flow easily, has a relatively low silica content, and turns into basalt, the rock, when solidified.
What is the difference in silica content and viscosity between light color and dark colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
What is Andesitic lava?
A stratovolcano is a name given to a volcano that has grown by progressive stacking of eruptive products (e.g. lava flows and pyroclastic flows). The term composite volcano is often preferred as it does not suggest that this stacking occurs in neat layers (i.e. 'strata' is a geological term for a layer of rock). Andesite is a type of igneous rock which is characterized by an intermediate amount of silica. It has more silica than basalts (e.g. Hawaii) and less silica than dacites (e.g. Mt. St. Helens).which it means active
Why are lava flows finer grained than intrusive igneous rocks?
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
Melted rock that flows to the surface cools quickly forms?
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.

What is An igneous rock with a low silica content that flows easily?
Basalt.
How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
What is the average silica content of a'a lava?
A'a lava has a generally low silica content. Having low silica content means that it also has a low viscosity level. Having a low viscosity level means that it flows easily.
Magma flows easily when it is low in?
Silica.
How does lava turn into basalt?
Basalt is a type of volcanic erock. It forms when lava that is low in silica and rich in iron and magnesium cools and hardens at or above Earth's surface, most often in the form of lava flows.
Which is characteristic of the magma that formed the Hawaiian islands?
magma that is low in silica and flows easily
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
Which chemical affects lava what makes it flow or explode?
There are a few different components. The ability of lava to flow is largely affected by silica content. More silica means the lava flows less easily. The explosive potential comes from gass trapped in the molten rock, which is released violently upon exposure to lower pressure. The primary gas is water vapor. Magma that is high in silica usually has a high gas content.
What affects the speed of lava flows?
The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
What type of lava flows easily?
Basaltic lava has a low viscosity which means it is thin and runny so it flows easily and spreads out.(:
How does low silica behave?
flows easily, so gas bubbles move up through it and escape fairly gently.
