If granite within earth melts and then erupts at the surface what type of extrusive rock is likely to form?
If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
What do obsidian pumice rhyolite and granite have in common?
Obsidian, pumice, rhyolite, and granite are all types of igneous rocks that form from the cooling and solidification of molten material from within or on the earth's surface. They have different mineral compositions and textures based on their specific formation processes.
What type of rock does magma make?
Magma cools and solidifies to form igneous rocks such as granite, basalt, and obsidian depending on the cooling rate and mineral composition.
Which rock has large mineral grains granite obsidian basalt or pumice?
Granite has large mineral grains compared to obsidian, basalt, and pumice. Granite is an intrusive igneous rock that forms deep within the Earth's crust, allowing for the growth of large mineral crystals due to slow cooling. Obsidian, basalt, and pumice are extrusive igneous rocks that cool quickly at the Earth's surface, resulting in smaller mineral grains or a glassy texture.
What type of rocks form from melting and cooling?
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
What volcano does obsidian come from?
Obsidian is a felsic glass. At depth, it will crystallize to form granite. On the other hand it turns into perlite on reacting with water. At high grade it recrystallizes to form felsic glass.
Can Obsidian turn into Granite?
No, Obsidian and Granite are two different types of rocks with distinct properties. Obsidian is a volcanic glass formed from rapidly cooling lava, while Granite is an igneous rock made up of various minerals like quartz and feldspar. They have different mineral compositions and formation processes, so Obsidian cannot turn into Granite.
How are granite and obsidian are different?
Granite is a rock, whereas obsidian is a type of glass formed by cooling lava.
Name 4 kinds of igneous rocks?
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
What does granite obsidian and pumice share?
They are all Igneous rocks.
What are the examples of ingeous rocks?
Obsidian, Granite, and i believe slate
What type of rocks are pumice obsidian and granite?
Igneous rocks
What is the same about granite and obsidian?
Obsidian and granite are both igneous rocks. Obsidian is of extrusive origin (which means the magma cooled quickly) and has a glassy texture. Granite is of intrusive origin (which means the magma cooled slowly) and is phaneritic, or coarse grained.y
If granite within the earth melts then erupts at the surface what type of extrusive rock is likely form?
A felsic extrusive igneous rock, such as rhyolite or obsidian.
If granite within earth melts and then erupts at the surface what type of extrusive rock is likely to form?
If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
What geological process is at work when obsidian or granite turns into sandstone or shale?
Compaction
What do obsidian pumice rhyolite and granite have in common?
Obsidian, pumice, rhyolite, and granite are all types of igneous rocks that form from the cooling and solidification of molten material from within or on the earth's surface. They have different mineral compositions and textures based on their specific formation processes.
