A shield volcano is a volcano that has gently sloping sides and form what looks like a shield. These volcanoes are typically non violent and have a central vent with lots of fissures and dikes of hot molten lava running down the side of these volcanoes. Shield volcanoes are gently sloping because the lava flowing from them is very fluid and runny, because of this the lava does not cool as quickly and stays heated longer.
The largest mountain in the world is Mauna Loa rising just 13,000 feet from the pacific ocean but its true height is 33,000 feet rising from the ocean floor.Find yourself a good science kit that explains how shield volcanoes are formed and who knows your son or daughter might just turn out to be a vulcanologist.

Composite Volcanoes are normally steep sided symmetrical cones that have built up over many years, ash and lava from previous eruptions hence the name composite. They normally have a crater or vent at the top. These volcanoes are also sometimes called strato volcanoes.
Some of the greatest volcanoes in the world are composite volcanoes like Mount St Helens and Mount Rainier in Washington. These composite volcanoes form along a convergent boundary or subduction zone that I blogged about before. The lava is thick and tends to get stuck in the vents and fissures of the volcano until gasses building up pressure explode causing violent eruptions. To learn more about composite volcanoes get yourself a volcano science kit and you just might find yourself wanting to be a volcanologist. Thanks Moorescience.
One of the signs that geologists use to predict a volcanic eruption is when a dormant volcano begins to experience more earthquakes on a frequent basis. Before the quiet Mount Saint Hellens blew there was a significant increase is earthquakes from the previous years. This could be an indication that magma is rising to the surface causing shallow quakes just below the surface of the earth.
For me earthquakes and volcanoes are just another sign that this is a living breathing planet that is in a constant state of change. A volcano science kit is a great way to learn about these changes in the earth. Though it may seem like an eruption causes great devastation the fascinating tale of regrowth after an eruption is truly inspiring. Thanks Moorescience
It was a calm day on Sunday may 18Th 1980 when suddenly a landscape of pristine old forrest was destroyed in just a moments time. Mt St Hellens volcano erupted with such force that a bulge of magma building in the volcano on the north side of the mountain triggered a 5.1 magnitude quake and caused the north side of the volcano to erupt.
Do some research of the Mount St Hellens volcano and if you ever plan on bringing the eruption to life, going there is a once in a lifetime event. After you have done your research why not back that research up by choosing one of the many volcano science projects that will excite the kid in all of us, why because I sure got excited when we did our project together.
