A science report on volcanoes

Volcanoes are like giant vents for the Earth. Imagine a pot of chili bubbling on the stove. The chili might just bubble up and erupt over the sides of the pan.

Take the lid off, though, and the heat can escape. Along with this rock are explosive gases. When these pieces rub up against each other, they create pressure. Magma and gases build up. As the magma, or lava, cools and hardens, it forms mountains over millions of years.

These mountains are known as volcanoes. They spew lava, rock, poisonous gases and ash with great power. As it pours out of the Earthit can burn anything in its path. Poisonous gases and ash can cause serious illness or death. The main parts of Volcano path. This means they have erupted recently or they might erupt.

Some volcanoes are extinct. Over 80 volcanoes have been found in the ocean. A volcano has three categories to fall under: Extinct was a volcano but will never erupt again or is not expectedDormant has not erupted in thousands of years but is likely to erupt againActive has the potential to erupt at any stage or has erupted since the last ice age.

Lava from volcanoes can reach temperatures of 2, degrees Fahrenheit. Volcanoes spew out ash and toxic gases, as well as lava and lava boulders.

Pompeii was an ancient city that was completely buried in ash and lava. Mauna Kea also in Hawaii is a taller volcano with a height of 4, m but currently is dormant. Mauna has not erupted since BC.

Are there any benefits to volcanoes? Volcanoes relieve pressure inside the earth, similar to when you lift the lid on a pot of simmering food. Soils around old lava fields are often fertile and grow good crops.

Are all volcanoes mountains? Sometimes volcanoes can be plateaus or even cracks in the ground. How serious are volcanoes to people? Most volcanoes occur where few people live, but when a volcano actively erupts, it can be very dangerous to anyone living nearby.

Overpeople have died in volcanoes in the last years. Many people live in the valley beneath Mt.

Whether your volcano is made out of papier-mâché, clay or cardboard, it could probably use some extra creativity. The erupting volcano has long been a science fair staple, but with a few bells and whistles, you can turn it into an even more impressive project. There are known active volcanoes in the United States, and 18 of them pose a "very high threat" of death and destruction to Americans living nearby, according to a new volcanic risk report.

Model volcanoes have been a standby of science fair projects for many students. The displacement of gas that is formed from the reaction has to go somewhere, typically out the opening to the environment.
