How do plants start growing on lava rock?

Answer 1

moisture and nutrients

Answer 2

Plants can start growing on lava rock through a process called primary succession, where pioneer species like mosses, lichens, and ferns establish themselves on the rock. These plants break down the rock through physical and chemical weathering, eventually creating soil for other plant species to grow. Over time, more complex plant communities develop on the lava rock as the soil continues to accumulate.
