Answer:Volcanoes are natural phenomena which are on the Earth’s surface through which molten rock and gases escape from below the surface
Explanation:These volcanoes are very interesting to observe and to study because of their amazing occurrences and majestic lava eruptions. Volcanoes have been studied ever since the beginning of mankind and the word “volcano” is thought to be derived from Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn originates from Vulcan, the name of a god of fire in Roman mythology. Consisting of several types, volcanoes can extrude several forms of magma and can also release multiple gases. These extruded materials can affect the Earth’s structure and atmosphere.

Last but not least, composite volcanoes also make up some of the earth’s surface. Composite volcanoes have a conical shape, with a steep summit area and gradually sloping flanks, and are nearly symmetrical in structure (Tarbuck, 141). These volcanoes release silica-rich and gaseous magma that is highly viscous and travels very short distances. These three types of volcanoes that occupy the earth have seemingly different physical characteristics and behavioral changes.
A volcanic eruption is one of the most dangerous and eventful natural disasters that can take place. During these eruptions, several factors are taken into account. Each type of volcano discussed above has a different form of lava: one’s might be highly fluid and the other might be very viscous. Lava can take many shapes as it is extruded from a volcano. One such form is that of pahoehoe. Usually common on the Hawaiian volcanoes, pahoehoe is a form of lava which is smooth and ropy and causes by the congealment of lava as it is released from the volcano
Explanation:
The name volcano comes from Vulcan, the Roman god of fire! A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here.
So did you know that volcanoes is more than 80% of the earth's surface is volcanic in origin. The sea floor and some mountains were formed by countless volcanic eruptions. Gaseous emissions from volcano formed the earth's atmosphere. There are more than 500 active volcanoes in the world.
volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
Now did you know that A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
I hope this is good and it work. if i give you a bad grade im so sorry but i hope you pass and get a good grade
