Solution(By Examveda Team)

Lava solidifies to form Basalt. Basalt is an extrusive igneous rock which is formed by rapid cooling of basaltic lava which is exposed near the surface of Earth. Basalt is a fine-grained, hard rock which forms when bits of lava shoot out of volcanoes. It forms when lava reaches the Earth's surface near an active volcano.
