Volcanoes are awesome manifestations of the fiery power contained deep within the Earth. These formations are essentially vents on the Earth's surface where molten rock, debris, and gases from the planet's interior are emitted. When thick magma and large amounts of gas build up under the surface, eruptions can be explosive, expelling lava, rocks and ash into the air. Less gas and more viscous magma usually mean a less dramatic eruption, often causing streams of lava to ooze from the vent. The mountain-like mounds that we associate with volcanoes are what remain after the material spewed during eruptions has collected and hardened around the vent. This can happen over a period of weeks or many millions of years. A large eruption can be extremely dangerous for people living near a volcano. Volcanoes tend to exist along the edges between tectonic plates, massive rock slabs that make up Earth's surface.

How Volcanoes Work" Whenever there is a major volcanic eruption in the world, you'll­ see a slew of newspaper articles and nightly news stories covering the catastrophe, all stressing a familiar set of words -- violent, raging, awesome. When faced with a spewing volcano, people today share many of the same feelings volcano-observers have had throughout human history: We are in awe of the destructive power of nature, and we are unsettled by the thought that a peaceful mountain can suddenly become an unstoppable destructive force! While scientists have cleared up much of the mystery surrounding volcanoes, our knowledge has not made volcanoes any less amazing. In this article, we'll take a look­ at the powerful, violent forces that create eruptions, and see how these eruptions build volcanic structures like islands.

GeoTopics @ GeoNet What is a volcano? A volcano is a conical hill or mountain formed by material from the mantle being forced through an opening or vent in the Earth's crust. back to top What are the main features of a volcano? Brought to You by Fireplace Spot When volcanoes are active, gas, ash, and hot magma can escape from them. These volcanic eruptions can be a violent yet spectacular vision. Volcanoes have been around since the Earth started forming. The word volcano originates from Vulcan, the name of the Roman God of fire.

Weather Wiz Kids weather information for kids Volcanoes (Volcanoes are not associated with weather, but instead are natural disasters.) What is a volcano?A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.

Weekly Reader Current Events A giant volcano on the island of Hawaii is becoming active, scientists say. A volcano is an opening in the earth through which gases, ashes, and melted rock may come. Sometimes these materials erupt, or come out, with such force that they rise high into the air. Other times, they flow out. A mountain formed by these materials is also called a volcano.

Volcano A volcano is a place on the Earth's surface (or any other planet's or moon's surface) where molten rock, gases and pyroclastic debris erupt through the earth's crust. Volcanoes vary quite a bit in their structure - some are cracks in the earth's crust where lava erupts, and some are domes, shields, or mountain-like structures with a crater at the summit. Magma is molten rock within the Earth's crust. When magma erupts through the earth's surface it is called lava. Lava can be thick and slow-moving or thin and fast-moving.

Online Activities: Weather Watch Volcanoes The Basics What is it? Fun Volcano Facts for Kids - Interesting Facts about Volcanoes Volcanoes are openings in the Earth’s surface. When they are active they can let ash, gas and hot magma escape in sometimes violent and spectacular eruptions. The word volcano originally comes from the name of the Roman god of fire, Vulcan.

Volcanic Hot Spots - Geology For Kids Volcanic Hot Spots In many locations the hot molten magma from deep within the Earth rises up through the crust to reach the surface. This sometimes happens in the middle of plates. When a hot spot forms in the middle of a plate, it remains constant, as the plate continues to move over it. The result is that a trail of volcanoes is left behind, with older volcanoes moving away from the hot spot, and newer ones forming over top of the hot spot. One of the most famous hot spots on Earth are the Hawaiian Islands.
