The rock that has the same composition as granite but smaller crystals is called rhyolite. Rhyolite forms from the rapid cooling of molten rock at or near the Earth's surface, which leads to the formation of its fine-grained texture. While both granite and rhyolite are composed primarily of quartz, feldspar, and mica, the slower cooling of granite allows for the development of larger crystals.
What else can I help you with?
Does Granite cools very quickly?
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 type of rock has course-grained crystals of all different shapes and sizes?
The type of rock that has coarse-grained crystals of various shapes and sizes is called igneous rock, specifically granite. Granite forms from the slow cooling of magma beneath the Earth's surface, allowing large crystals to develop. Its composition typically includes quartz, feldspar, and mica, resulting in a diverse range of crystal shapes and sizes.
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.
Is marble rock granite?
No, marble and granite are two distinct types of rocks. Marble is a metamorphic rock primarily composed of calcite or dolomite crystals, while granite is an igneous rock made up of various minerals such as quartz, feldspar, and mica.
What type of rock is hard wearing and and has large crystals?
Granite is a type of rock that is hard-wearing and commonly has large crystals. This igneous rock forms from the slow cooling of molten rock beneath the Earth's surface, allowing for the growth of large crystals like feldspar, quartz, and mica. Granite is known for its durability and is often used in construction for countertops, flooring, monuments, and other applications where a tough, long-lasting material is needed.
What is an extrusive igneous rock with a composition similar to granite but with smaller crystals?
An extrusive igneous rock with a composition similar to granite but with smaller crystals is called rhyolite. Rhyolite forms from the rapid cooling of magma at the Earth's surface, resulting in fine-grained crystals. It is light in color and rich in silica, similar to granite.
An extrusive rock with a composition similar to granite but with smaller crystals?
The rock is likely a rhyolite, which is an extrusive igneous rock with a composition similar to granite but formed from rapidly cooling lava, resulting in smaller crystals. Rhyolite typically exhibits a fine-grained texture due to its quick cooling process at the Earth's surface.
What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.
If a granite rocks was made of smaller crystals if would be called?
If a granite rock is made of smaller crystals, it would be called fine-grained or fine-grained granite.
What is an example of an intrusive igneous rock with large crystals?
Porphyrite of any composition, granite, gabbro, diorite. Most intrusive igneous rocks have crystals large enough to see with the naked eye. Another term used to define an igneous rock with large crystals is coarse-grained.
Which rock has big crystals?
granite!
What is Granite crystal?
Granite is an igneous rock with visible mineral crystals.
Does Granite cools very quickly?
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 is an extrusive igneous rock with large crystals?
granite
What is the grain shape for granite?
Granite typically has a coarse-grained texture, with interlocking crystals that are visible to the naked eye. The grains in granite are typically irregular in shape and can vary in size, depending on the specific mineral composition of the rock.
What is a hard rock made of crystals-not permeable?
granite is a hard rockk madeof crystals
Is granite homogeneous?
No. If you look at granite you can see that there are distinct crystals of diferent minerals. Thus, granite is heterogeneous.
