Since basalt is extrusive it cools quickly and forms small crystals.
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
Basalt typically has smaller crystals than granite. This is because basalt cools and solidifies quickly on the Earth’s surface, limiting crystal growth, while granite forms beneath the surface and has more time for larger crystals to develop.
Basalt formations can be massive, encompassing many square miles. The mineral crystals which make up basalt require magnification to see.
Pillow basalt is formed from solidifying lava which erupts under the surface of a body of water. Because of this, it cools much faster, allowing less time for crystal growth.

Granite with larger crystals, basalt with smaller crystals.
1.because it is called a extrusive rock 2. it doesnt have big crystals
The will be large in an extrusive granite and fine in an intrusive basalt.
Basalt crystals are typically small to microscopic in size due to the rapid cooling of lava, which results in limited time for crystal growth. This rapid cooling process usually prevents the development of large crystals in basalts.
Crystals in basalt that formed underwater are smaller because they cool faster in the water, resulting in less time for the crystals to grow. On the other hand, crystals in basalt that formed on the ground have more time to grow as they cool more slowly, leading to larger crystal sizes.
relativity small
it cooled quick
Basalt typically has a fine-grained crystal size, usually referred to as aphanitic, meaning the crystals are too small to be seen with the naked eye. This results in a smooth or glassy texture in basalt rocks.
Basalt formations can be massive, encompassing many square miles. The mineral crystals which make up basalt require magnification to see.
