Three Main Types of Volcanoes The three main types of volcanoes differ in shape‚ size‚ and make-up; the differences partly result from the different types of eruptions.

Earth’s volcanoes occur because the planet’s crust is broken into 17 major‚ rigid tectonic plates that float on a hotter‚ softer layer in the Earth’s mantle.[1] Therefore‚ on Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. For example‚ a mid-oceanic ridge‚ such as the Mid-Atlantic Ridge‚ has volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates coming together. Volcanoes can also

[pic]! [pic] ‘I’ll go out for a breath of fresh air’ is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world‚ because the quality of air in our cities is anything but fresh. The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus‚ car‚ or a scooter; smoke billowing from a factory chimney‚ flyash generated by thermal power plants‚ and speeding cars causing dust

There are two types of volcanoes‚ strato-volcanoes and shield volcanoes. Both are characterized differently‚ for example‚ strato volcanoes have sleep slopes‚ shaped like a tall narrow cone‚ but shield volcanoes have gentle slopes‚ shaped like a low‚ wide cone. The eruptions can be devastating‚ an example would be mount vesuvius‚which erupted in AD 79‚ killing over 10‚000 to 25‚000. Strato volcanoes are the larger and more impressive volcanoes with a snow capped peak which can easily exceed

The rhythms or musical airs of the vallenato are the paseo‚ merengue‚ puya‚ son and tambora. Vallenato is not a ballroom dance‚ it is closely linked with the Colombian idiosyncrasy.

Mount Etna Sicily ’s greatest natural attraction is also its highest mountain. To the ancient Greeks‚ Mount Etna was the realm of Vulcan‚ god of fire‚ and the home of the one-eyed monster known as the Cyclops. At approximately 3350 meters‚ it is Europe ’s highest active volcano. The height of its summit changes with each eruption‚ and over the centuries a few lava flows have reached the coast. Over 1200 square meters of Etna ’s surface is covered with solidified lava. Etna offers skiing in

Premium Volcano Earth Lava
Earth’s crust that float on the mantle. These plates are constantly moving and may crash into each other or slide or move apart from each other. Continental Plate: Large sections of the surface of the Earth that move separately. Shield Volcano: Volcanoes formed by viscous lava and have broad and flat sides. This happens due to the lava cooling slowly which lets it spread widely before cooling. Magma: Molten or partly molten rock underneath the Earth’s surface. Seismic Activity: Release of energy

BOT 450 TR 10:30-11:20 Volcanoes are magnificent formations from an opening in a planet’s crust. They form when magma‚ volcanic ash‚ and gases escape from a magma chamber below the surface of the planet. Tectonic plates cover the surface of the planet and are constantly moving. Volcanoes are generally found where these plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning. There are volcanoes that form away from plate
