Basalt – Noam Yadgar


“Basalt (once was lava) known for being a hard, light and dark rock.
Its common “spongy”, “vesicular” texture is caused by trapped gasses during the hardening of the rock from lava.
Lava can get hot, up to 1200 Celsius and flow at a speed up to 50/60kph! while flowing down the volcano mountain, the lava is slowing down and forming into Basalt rock and will finally stop and remain a frozen picture.”
