i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.

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 can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
because they take longer to cool from the magma it is formed from
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.
Both granite ans basalt are types of igneous rock.
Basalt typically has a higher specific gravity than granite due to its more dense and heavy composition. This means that basalt is usually heavier for its size compared to granite.
