Question

positive effects of volcanic eruption in the form of mind map
please help guys​

Answer 1

Answer:

Earth is active, geologically speaking and as such, it undergoes a process of constant renewal by way of volcanic eruptions.  Volcanoes erupt when magma reaches the surface due to high pressure and starts to pool in a magma chamber. The resultant high pressure, the density of the magma pushes up the crust so that a cone-shaped structure takes shape; eventually, the pressure in the magma chamber builds up to high levels, eventually resulting in a volcanic eruption of ash, lava, and other gases and particulates. While at the outset, it may seem that a volcanic eruption is a disruptive event, and causes widespread damage, the fact is that the same volcanic eruption can prove beneficial to the local environment. This is why we need to take a closer look at some of the positive and negative effects of volcanic eruptions.
