The rock formed from slow cooling magma below the surface has large crystals because the crystals have had a large amount of time, because of the insulating effects of the surrounding material, to gather elements necessary for crystal production as they move around in the liquid material. Once solidified, crystal growth stops.
Igneous rocks can have both small and large crystals, depending on how quickly they cool. If an igneous rock cools slowly beneath the Earth's surface, it can form large crystals, while rapid cooling at the Earth's surface or in an eruption can result in small or no visible crystals.
The rock is called porphyry, which forms when magma slowly cools beneath the Earth's surface. The large crystals are known as phenocrysts, and the smaller surrounding crystals are called groundmass or matrix.
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
No, melted rock that cools quickly result in igneous rock with large minerals because large crystals take time to form and the rocks that usually have them are the ones that were formed inside the earth.
It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.
When magma cools slowly below Earth's surface, it forms rocks with large crystals. This slow cooling allows more time for crystals to grow to a larger size compared to rocks that cool quickly at the surface. Examples of these rocks include granite and diorite.

Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
intrusive igneous
Igneous rock, such as granite or diorite, is formed from magma that cools below the Earth's surface. It has a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form.
The crystals may display a "Crescumulate texture".

When liquid rock cools slowly beneath the Earth's surface, intrusive igneous rocks are formed. These rocks have large crystals due to the slow cooling process, allowing sufficient time for mineral grains to grow. Examples include granite, diorite, and gabbro.
