–What is a Volcano?<\/u><\/strong><\/p>\n

Volcanoes are holes in the Earth from which molten rock, gas and ash erupt.\u00a0 Magma is the name for molten rock mixed up with gas and sometimes gas bubbles, whilst it is still under the ground. \u00a0Lava is the name for when it breaks through the Earth\u2019s surface, and you probably know this already, but lava is seriously hot.\u00a0 When we talk about erupt it means to burst out in a rather dramatic way!<\/p>\n

The Earth\u2019s surface, called\u00a0the crust<\/a>, is made up of huge slabs called\u00a0plates. They fit together like a jigsaw puzzle. When these plates move and crash against each other the one that slides underneath is pushed down and magma squeezes up between them and rises to the surface of the earth. This then makes bubbles of gas which can cause pressure to build up and eventually explode<\/p>\n

–What causes Volcanoes?<\/u><\/strong><\/p>\n

Volcanoes<\/strong>\u00a0happen when magma rises to the surface of the earth, which\u00a0causes <\/strong>bubbles of gas to appear in it. This gas can\u00a0cause<\/strong>\u00a0pressure to build up in the mountain, and it eventually explodes. When the magma bursts out of the earth, it is called lava.<\/p>\n

–How are Volcanoes Formed<\/u>?<\/strong><\/p>\n

Way deep down in the Earth, in the Earth\u2019s upper mantle, you\u2019ll find magma, debris and gases. When magma works itself up through the Earth\u2019s surface it erupts through a vent to create lava flows and ash deposits. It is one of nature\u2019s unbelievable natural events.<\/p>\n

–Why do Volcanoes Erupt?<\/u><\/strong><\/p>\n

The Earth\u2019s crust is made up of huge slabs, and these are called plates. Think of them like a massive big jigsaw puzzle where the pieces all fit together. Sometimes these plates move. This causes friction. When there is friction then this causes earthquakes and volcanic eruptions of the plates. This theory is called plate tectonics.<\/p>\n
