Since basalt is extrusive it cools quickly and forms small crystals.
i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
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.

No. Basalt generally has small crystals.

Granite with larger crystals, basalt with smaller crystals.
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form 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 is 1mm
relativity small
it cooled quick
