glassy texture
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.
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.
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.
Igneous rocks are formed when molten hot rock flows to the surface of the Earth and rapidly cools down. The crystals that form are rich in silicon and oxygen.
Igneous rock that cools quickly may have a fine-grained texture, with small mineral crystals that are not easily visible to the naked eye. Examples include basalt and rhyolite.
glassy texture, hope this helps :)

Small
If lava cools quickly, the minerals don't have as much time to form crystals, so the crystals do not become very large. Igneous rocks that cooled quickly and have small crystals are described as "aphanitic" igneous rocks.
Small ones.
Lava cools quickly and forms rocks with small crystals. They are called extrusive igneous rocks.

The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.
Extrusive igneous rock forms when lava cools quickly on the Earth's surface. This rapid cooling prevents large crystals from forming, resulting in a finer-grained texture. In contrast, intrusive igneous rock forms when magma cools slowly beneath the surface, allowing for the development of larger crystals.
Yes, when magma cools slowly, the atoms have more time to arrange themselves into orderly patterns, leading to the formation of larger crystals. This results in coarse-grained igneous rocks with visible crystals, such as granite.
