17 explosive volcano facts!

Studying at Cambridge. Iceland sits on crack in the surface of the earth where two tectonic plates large blocks that make up the outer most layer of the earth are ripping apart from each other. These two blocks are moving apart at around 2 cm a year about the rate that your finger nails grow and are slowly widening the Atlantic Ocean, increasing the distance from Europe to North America. As the tectonic plates split apart magma molten rock wells up from below forming volcanoes which create new land in between. This rifting process is happening all the way down the middle of the Atlantic Ocean beneath the sea. But in Iceland we see the process on land because a hot upwelling from deep within the earth also sits beneath Iceland pushing it upwards out of the sea and making the area even more volcanically active.

Is it just us or is it getting hot in here, gang? Great for teachers, homeschoolers and parents alike! Volcanoes are classified as active, dormant or extinct depending on the amount of volcanic activity happening. When you imagine a volcano, you might picture it as a large, slope-sided mountain, but volcanoes can actually be a variety of shapes. Shield flat , composite tall and thin , cinder cones circular or oval cones , and lava domes where dome-shaped deposits of hardened lava have built up around the vent, as the lava is too thick to flow very far. Magma is the name given to hot liquid rock inside a volcano.

The largest recorded earthquake in the United States was a magnitude 9. The largest recorded earthquake in the world was a magnitude 9. The earliest reported earthquake in California was felt in by the exploring expedition of Gaspar de Portola while the group was camping about 48 kilometers 30 miles southeast of Los Angeles. Before electronics allowed recordings of large earthquakes, scientists built large spring-pendulum seismometers in an attempt to record the long-period motion produced by such quakes. The largest one weighed about 15 tons. There is a medium-sized one three stories high in Mexico City that is still in operation.

Some, but not all, earthquakes are related to volcanoes. For example, most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma. Most earthquakes directly beneath a volcano are caused by the movement of magma. The magma exerts pressure on the rocks until it cracks the rock. Then the magma squirts into the crack and starts building pressure again.

Yet another catastrophic force is the earthquake. Believe it or not, earthquakes have been responsible for killing over 13 million people in last 4, years. The actual figure may be way more than that. Anyway, we hear about earthquakes killing people every year but did you ever wonder, what causes them? Where do they originate from?
