Volcano Eruptions

Volcanic Eruption

By Mark Diaries

​A volcano’s structure can influence how it erupts. Some volcanoes have only one central vent, while others have numerous fissures that allow lava to escape. Materials in magma influence its viscosity, or how it flows. If magma is a thin fluid – not viscous – gases can escape easily. But if magma is thick – viscous – gases cannot escape as easily. This builds up pressure within a volcano.

INTRODUCTION

​

A chemical reaction between vinegar and baking soda creates a gas called carbon dioxide. Carbon dioxide is the same type of gas used to make the carbonation in sodas. What happens if you shake up a soda? The gas gets very excited and tries to spread out. There is not enough room in the bottle for the gas to spread out so it leaves through the opening very quickly, causing an eruption!

​Some text here about the topic of discussion.

A volcanic eruption is when lava and gas are released from a volcano—sometimes explosively. The most dangerous type of eruption is called a 'glowing avalanche' which is when freshly erupted magma flows down the sides of a volcano. They can travel quickly and reach temperatures of up to 1,200 degrees Fahrenheit.
