Where magma erupts on the surface of the earth, temperatures are lower and cooling of the magma takes place much more rapidly. This is the extrusive or volcanic environment and results in extrusive or volcanic igneous rocks.

Why are granitic magmas thicker than basaltic magmas?
Granitic magmas are thicker than basaltic magmas because they have higher silica content, which increases viscosity. The higher silica content leads to stronger bonding between the silica tetrahedra, making it more difficult for the magma to flow. Basaltic magmas, on the other hand, have lower silica content and are less viscous, allowing them to flow more easily.
Can magmas be classified as intrusive or extrusive?
Yes, magmas can be classified as intrusive or extrusive. Intrusive magmas form underground as the magma cools slowly, resulting in large crystals. Extrusive magmas, on the other hand, cool quickly on the Earth's surface, leading to fine-grained or glassy textures like obsidian or basalt.
What kind of magmas produce violent volcanic eruptions?
Magmas with high viscosity and gas content tend to produce violent volcanic eruptions. High viscosity magmas are thicker and have more difficulty releasing gas, leading to pressure build-up and explosive eruptions. This often occurs with felsic or rhyolitic magmas.
How hot does magma have to be to explode?
The explosive potential of magma depends more on viscosity gas content than on temperature. Most magmas are at temperature of at least 700 degrees Celcius. Interestingly, the most explosive magmas are the high-silica magmas, which have lower melting temperatures.
Why do silica-poor magmasproduce broad volcanoes with general slopes?
Because low silica magmas tend to be hotter and more fluid/runny than high silica magmas.
After what are magmas named?
Magmas are named according to their percentage of silicate mineral content .
Why are granitic magmas thicker than basaltic magmas?

How are felsic magmas formed?
Heat from the mantle melts part of the lower crust

How does water vapor effect magmas properties?
cosolidation
Are magmas classified as intrusive and extrusive?
Yes, magmas can be classified as intrusive or extrusive. Intrusive magmas cool and solidify beneath the Earth's surface, forming intrusive igneous rocks like granite. Extrusive magmas erupt onto the Earth's surface and solidify quickly, forming extrusive igneous rocks like basalt.
