Fine-grained igneous rocks are formed when magma cools quickly at or near the Earth's surface, resulting in rapid crystal formation. This rapid cooling prevents large mineral crystals from forming, giving the rock its fine-grained texture. Examples of fine-grained igneous rocks include basalt and rhyolite.
What else can I help you with?
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
What is the origin of the fine grained igneous rock?
Uplift and solidification
A coarse-grained rock and a fine-grained rock probably had different what?
Methods of formation. If crystalline (igneous or metamorphic) they would most likely have had differing rates of cooling. If sedimentary, they would most likely have had differing depositional environments (higher energy for larger grain sizes).
What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
What are two examples of fine-grained igneous rock?
Two examples of fine-grained igneous rocks are basalt and rhyolite. Basalt is a dark-colored rock with a composition rich in iron and magnesium, while rhyolite is light-colored and has a high silica content. Both rocks form from the cooling and solidification of molten magma.
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
How does fine grained igneous rock form?
when the lava cools quickley it is fine-grained
What does a fine-grained igneous rock form from?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
What are two different igneous rock textures?
*fine-grained *coarse-grained
What igneous rock are fine-grained due to fast cooling?
Basalt
What type of rock is pumice?
It is an igneous (volcanic rock).
What is the cooling environment of a fine grained igneous rock?
A fine-grained igneous rock forms from magma cooling quickly at or near the surface of the Earth. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture with small mineral grains. Examples of fine-grained igneous rocks include basalt and rhyolite.
Which the following is a fine grained light colored extrusive igneous rock?
fine grained extrusive rocks can contain Potassium and Plagioclase Feldspar, Quartz, Biotite, Amphibole, Pyroxene and Olivine. these are all the choices for every igneous rocks
What is the origin of the fine grained igneous rock?
Uplift and solidification
What is the texture of the rock andesite?
The texture of Andesite rock is fine-grained and it Extrusive plus it is an igneous rock .
