What type of volcano is Aracar?
Aracar is a steep-sided stratovolcano with a youthful-looking summit crater 1-1.5 km in diameter that contains a small lake. It is located just east of the Argentina-Chile border. The volcano was constructed during three eruptive cycles dating back to the Pliocene.
What is volcano terminology?
Strictly speaking, the term volcano means the vent from which magma and other substances erupt to the surface, but it can also refer to the landform created by the accumulation of solidified lava and volcanic debris near the vent.
Where is volcano lava located?
Molten rock below the surface of the Earth that rises in volcanic vents is known as magma, but after it erupts from a volcano it is called lava.
What is the top crater of a volcano called?
Craters at the top of volcanoes are called summit craters. Summit craters are where volcanic material is at or near the Earth’s surface. Volcanoes may have one summit crater, such as Mount Fuji in Japan.
Where does most intraplate volcanic activity occur?
Most geological activity takes place at plate boundaries. But some activity does not. Much of this intraplate activity is found at hot spots. Hotspots are plumes of hot material that rise through the mantle.
What is the 5 description of volcano?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.
Where is this massive volcanic crater?
The Ngorongoro Crater in Northern Tanzania, once a gigantic volcano, is the largest intact caldera in the world.
What’s the difference between volcanic crater and caldera?
A caldera is a depression created after a volcano releases the majority of the contents of its magma chamber in an explosive eruption. Craters are formed by the outward explosion of rocks and other materials from a volcano. Calderas are formed by the inward collapse of a volcano.
