The article offers information on volcanoes. A volcano is described as an opening in the ground or on top of a mountain. One of the world's most active volcanoes is Kilauea, which is almost always erupting. According to scientists, there are more than 500 active volcanoes in the world. The hot liquid rock deep inside the Earth is called magma. The hot melted rock that goes out of a volcano is called lava.

    Information on volcanoes is provided. A volcano is a mountain or hill cone with an opening on top known as a crater. Hot melted rock (magma), gases, and other material from inside the earth mix together underground, rising up through cracks and weak spots. When enough pressure builds up, the...

    Volcanoes are places where magma emerges through the crust and onto the surface. The word volcano comes from Vulcano Island in the Mediterranean. There are many types of volcanoes and the most distinctive are the cone-shaped composite volcanoes which build up from alternating layers of ash and...

    We report here the most complete dataset for major and trace elements, as well as Sr isotopic compositions, of magmas erupted by Stromboli since the onset of present-day activity 1,800 years ago. Our data relate to both porphyritic scoria and lava originating in the uppermost parts of the...

    The article presents information on Mount Erebus, Antarctica, which is one of the world's oddest volcanoes. The volcano's steam melts nearby ice, creating a landscape in which ice caves on the slopes of the volcano. Mount Erebus has a rocky top layer, the crust, which is made up of huge parts of...

    This article discusses how volcanoes begin and traces various events that lead to volcanic eruptions. Magma, which is melted rock, melts some of the rock inside of the earth and creates a gas. This gas rises up near the surface and forms a magma chamber, a pocket of magma just below the surface...

    Volcanic eruptions are produced by magma, the hot liquid rock under the Earth's surface. Magma is less dense than the rock above and so it tries to bubble to the surface. Explosive eruptions are driven by expanding bubbles of carbon dioxide gas and steam inside the magma. Magma near...
