Basalt and Granite are both made from the same magma.
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.
Dude, i know what your playing at. I have the exact same book you have/had. seriously. Why are you doing this for every single question? Do you really think it's gonna help you in the long run? Just think about it.could just answer it+ your doing the exact same thing or else you wouldn't be able to commentthink about it
There are many different types of ignoues rock, but as a general description, mafic, felsic and intermediate rocks are formd from basaltic, granitic, and andesitic magmas respectively.
Basaltic magma is considered "dry" because it has relatively low water content compared to other types of magma. This is why basaltic eruptions tend to be less explosive compared to more water-rich magmas like andesitic or rhyolitic magmas.
granitic is light, basaltic is dark.
basaltic
Baslatic magma is hotter.
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
The most common type of lava is basaltic. However some lavas may be andesitic or ryolitic. Rhyolite is the extrustive equivalent of granite.
Basaltic magmas are typically formed by partial melting of the upper mantle, specifically the mantle wedge above subduction zones. This process occurs at high temperatures and low pressures, resulting in the generation of magma rich in iron and magnesium. The melting of granite in the lower crust is less common but can also give rise to basaltic magmas through processes such as assimilation and fractional crystallization.
Yes, rhyolitic magmas are several hundred °C colder than basaltic magmas. This is because the melting point of a rhyolitic magma is much lower than that of basaltic magma. Instead of heating up rhyolitic magma much above its melting point it will ascend and either crystallize in the Earth's interior as a pluton or erupt.
A lava butte is generally basaltic lava. Granitic lava flows (called rhyolitic when they form at the surface) are rare and do not cover much ground.
