Expert Answer:

Lava is the hot molten rock which erupts after a volcanic eruptio. When lava comes to the surface of the earth, it cools and solidifies. This lava is rich in minerals. Further, the the lava and the volcanic ash often contains minerals that are beneficial to plants, and if it is very fine ash it is able to break down quickly and get mixed into the soil. Black soil is also formed as a result of volcanic activity. This soil is useful for growing cotton. Thus, lava activity is profitable for humans.
