Porphyritic
Particles vibrate faster when they are heated.
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
No, not all lava crystallizes to form igneous rocks with phaneritic textures. Phaneritic textures are characterized by large, visible crystals, which form when magma cools slowly beneath the Earth's surface. Lava that cools quickly on the Earth's surface forms igneous rocks with aphanitic textures, characterized by fine-grained or glassy structures.
Intrusive igneous rocks form underground from magma that cools slowly, resulting in coarse-grained textures. They have large mineral crystals visible to the naked eye, such as feldspar, quartz, and mica. Examples include granite, diorite, and gabbro.
The result of a slowly warming climate is likely to include rising global temperatures, more frequent extreme weather events, melting ice caps and glaciers, sea level rise, and shifts in ecosystems and biodiversity. These changes can have widespread impacts on human societies, economies, and natural systems.
When magma cools inside Earth, it forms igneous rocks like granite or basalt. The cooling process can result in different textures, such as fine-grained or coarse-grained, depending on whether the magma cooled quickly or slowly.
Particles vibrate faster when they are heated.
A crystal is a homogeneous solid substance that has a natural geometrically regular form. The crystals that form in slowly cooled magma produce large grains.

Crystallisation
Granite is an example of an igneous rock that cooled slowly underground and contains mostly quartz and potassium feldspar.
Cooling rates. A coarse-grained rock likely cooled slowly, allowing larger crystals to form, while a fine-grained rock probably cooled quickly, resulting in smaller crystals.
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.
Igneous rocks that cooled slowly are intrusive. Igneous rocks that cooled quickly are extrusive. Intrusive rocks form larger crystals, because the crystals have a longer time to grow. Extrusive rocks have small to no crystals, because they had little or no time to grow/form.
If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big
It will convert from magma to some form of intrusive igneous rock.
