No. Granite cools relatively slowly; its large crystals are one method of observing this. Granite is referred to as a "phaneritic" igneous rock, meaning that it is coarse-grained. Coarse-grained rocks cool slowly, which means that the minerals have time to form large crystals before the rock solidifies. A rock with the same composition as granite that does cool quickly is called rhyolite.
What else can I help you with?
Granite and ryholite have similar composition but granite is course-grained whereas rhyolite is fine grained what is the difference?
The main difference is in the cooling rate - granite cools slowly beneath the Earth's surface, allowing larger crystals to form, giving it a coarse-grained texture. Rhyolite, on the other hand, cools rapidly at the surface, leading to smaller crystals and a fine-grained texture.
What is one similarity between Granite and Rhyolite?
Both granite and rhyolite are felsic igneous rocks formed from very viscous silica rich magma. They have essentially the same composition. The difference between them is that granite cools slowly underground, forming large crystals while rhyolite cools rapidly above ground after a volcanic eruption forming small crystals or no crystals.
Can granite form as a lava flow?
No, granite does not form as a lava flow. Granite forms deep underground from the slow cooling of magma. Lava flows are composed of different types of igneous rocks, such as basalt or andesite, that form at the Earth's surface during volcanic eruptions.
What will form when magma cools?
When magma cools, it can solidify into different types of igneous rock depending on the cooling rate. Slow cooling can form coarse-grained rocks like granite, while rapid cooling can form fine-grained rocks like basalt. If the magma cools very quickly at the Earth's surface, it can solidify into volcanic glass like obsidian.
Granite and what are made when magma cools?
Granite and basalt are made when magma cools. Granite forms from slow-cooling magma underneath the Earth's surface, while basalt forms from rapidly-cooling magma on the surface.
Is volcanic glass a Granite?
No. Granite cools from magma deep underground. Volcanic glass cools quickly at or near the surface.
How does granite form into Obsidian?
Granite does not directly transform into obsidian. Obsidian is formed when lava cools very quickly, without giving crystals a chance to form. Granite, on the other hand, forms deep beneath the Earth's surface through the slow cooling and solidification of magma. So, while both are igneous rocks, they form under different conditions.
Which igneous rock cools the slowest pumice and Granite?
Granite cools slower than pumice. Granite forms deep underground, allowing it to cool slowly and develop large mineral grains, whereas pumice cools quickly on the Earth's surface due to its volcanic origins, resulting in a fine-grained texture.
Is granite a sedementary rock?
No, Granite is an igneous rock. It has a very mottled appearance because it cools very slowly allowing the different constituent minerals to form crystals.
Did granite cool slowly or quickly?
Granite cools slowly underground, allowing for the formation of larger crystals. This slow cooling process contributes to its coarse-grained texture and characteristic patterns.
The volcanic equivalent of granite is?
The volcanic equivalent of granite is rhyolite. Both granite and rhyolite are composed mainly of light-colored minerals such as quartz and feldspar, but rhyolite forms from volcanic magma that cools quickly at the Earth's surface, resulting in a fine-grained texture.

What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
