                          1. volcanic rocks are rich in minerals and when weathered, form fertile soils. These are ideal for growing crops.
                          2. Mineral Extraction
                            1. many valuable minerals form when volcanic activity occurs.
                            2. Tourism
                              1. volcanic landscapes can have beautiful scenery that attracts many visitors.
