6. Effect Of Volcano The first is how the weather near an erupting volcano is being affected. The second is how large eruptions will affect the weather/climate around the world. I think more people are worried about the second issue than the first. As far as we know, the main effect on weather right near a volcano is that there is often a lot of rain, lightning, and thunder during an eruption. This is because all the ash particles that are thrown up into the atmosphere are good at attracting/collecting water droplets. Another problem in Hawaii is that involves the formation of volcanic fog. The ongoing eruption is very quiet, with lava flowing through lava tubes and then into the ocean.

9. How Volcanoes Erupt While the shape and size or a volcano may vary the way that it erupts does not. Every volcano has what is known as a magma chamber. This is where hot, molten rock from the earth’s mantle collects. The process of a volcano erupting begins when the pressure in a magma chamber begins to build. This may be caused by the movement of the tectonic plates forcing the magma into smaller areas or the buildup of gases as more magma fills the chamber as plates move apart. The building pressure causes the magma to rise up a series of conduits inside the volcano. When it reaches the fissure or crack at the top of the volcano it erupts. The size of the eruptions depends on a number of factors such as: How much magma is in the chamber prior to eruption How much gas is present in the chamber and the magma itself How much silica is in the magma If there was any water present
