Consequences of the volcanoes

Volcanic eruptions have very dangerous effecs such as cause earthquakes, fast floods, mud slides, and rock falls., also the lava can travel very far and burn, bury, or damage anything in its path, including houses, trees, and people. The large amount of dust and ash can cause roofs to fall, makes it hard to breathe, and is normally very smelly. finally the ground around the volcano is not secure and can cause big earthquakes.

In the other hand volcanos can have positive effects for example them give vitamins to the soil around them also volcanic ash contains minerals that help plants grow, and if the ash is very soft, it will quickly get mixed into the soil in the same way  their sides are often steep and hard to reach, making them a safe place for plants and animals to live moreover, volcanoes are a very important source of life, further their gases are what created our water and atmosphere.
