Volcanos+Part+2

Volcanos can form on land but they can also form in water. Volcanos can help build up the Earth's surface (constructive) like the developing Hawaiian Islands, but volcanos can also be very destructive to the Earth's surface.

Volcanos can endanger anything that happens to be in the vicinity of an erupting volcano such as humans, property, and agriculture. Volcanos are destructive because when they erupt not only can they spew hot ash and lava but they can also cause other destructive activities to occur. Lava flows can destroy homes, grass, trees, and anything else in its destructive path. The lava which is hot melted rock flows from one place to another burning everything it touches. There are many constructive properties of volcanos. For example, volcanos help the rock-cycle by bringing rocks to the surface to form new landforms like islands. All of the Hawaiian Islands were created by volcanos. There is even a new island forming right now. Another example of a volcanos' constructive force is that if there are enough eruptions or a constant lava flow a mountain can form. Some of these mountains form on land but many build from the bottom of oceans.

**__ Other Constructive Effects of Volcanos __**   • volcanic ash can be used as an abrasive or cleaning agent • volcanic ash can act as a mulch • volcanos can create geothermal energy • ashes can make more fertile soil
