Answer 2

Igneous comes from the Latin word ‘ignis’ which actually means fire. Igneous rocks are a word used for rocks that have formed by the cooling and hardening of molten lava or magma. The atoms and molecules of melted minerals are what make up magma.
These atoms and molecules rearrange themselves into cool mineral grains as the magma cools, forming rocks as the mineral grains grow together. These rocks are therefore made from minerals that help plants grow.
