1.because it is called a extrusive rock
2. it doesnt have big crystals
Basalt cools off quickly because it is formed under water.
Since basalt is extrusive it cools quickly and forms small crystals.
Basalt cools fast because it is at the surface, where air carries heat away rather quickly.
Lava will cool quickly compared to underground magma.
it comes from magma inside the volcanoes then it cools and it turns in to basalt
Basalt is formed when low-silica lava erupts from a volcano and later cools.
igneous rocks are melted rocks and melted metal that cools quickly or slowly from a volcano and usually from magma.
i dont know thats why i am asking you do you know
Most lava forms a rock called basalt when it cools.
Basalt
Basalt is an igneous rock formed at or near the surface. It can be drawn into the mantle through the movements of plates at subduction zones.
Basalt is considered igneous because it forms when mafic lava cools at Earth's surface.
