What do you mean by volcanic mountain?
Volcanic mountains are a special class of mountains. A volcano is a vent or opening through which magma, ash, gases, and water vapour are ejected out. Volcanic mountains consist of – Magma chamber, Vent, Lava, Crater, and pyroclastic flow. Volcanic soil or the soil around a volcanic mountain is very fertile.
What is volcanic mountain short answer?
When the magma finds its way to the surface, it erupts as lava, rock, ash and volcanic gases; this is a volcanic mountain. A volcanic mountain starts out as a simple crack in the Earth called a volcanic vent. Magma erupts out of the ground as lava flows, clouds of ash, and explosions of rock.
What are volcanic mountains for Class 6?
(4) Volcanic mountains: These mountains are formed as a result of the cooling down of lava and other materials that come out of a volcano during volcanic eruptions. Mount Kilimanjaro (Tanzania) is an example of a volcanic mountain.
What is the other name for volcanic mountain?
volcano. (redirected from Volcanic mountain) Also found in: Thesaurus, Medical, Encyclopedia. Related to Volcanic mountain: plateau mountain. volcano.
Is an example of a volcanic mountain?
Volcanic Mountains are formed due to the performance of volcanic activity. Mount Kilimanjaro in Africa is one of the examples of the volcanic mountains. Volcanic mountains contain – Magma chamber, Vent, Lava, Crater, and pyroclastic flow. Mount Kilimanjaro in Africa is one of the examples of the volcanic mountains.
What are volcanic mountains examples?
The most important types of volcanic mountain are composite cones or stratovolcanoes ( Vesuvius, Kilimanjaro and Mount Fuji are examples) and shield volcanoes (such as Mauna Loa on Hawaii, a hotspot volcano). A shield volcano has a gently sloping cone due to the low viscosity of the emitted material, primarily basalt.
What causes volcanic mountains?
Volcanic mountains are formed when a tectonic plate is pushed beneath another (or above a mid-ocean ridge or hotspot) where magma is forced to the surface. When the magma reaches the surface, it often builds a volcanic mountain, such as s shield volcano or a stratovolcano.
Why are volcanic mountains important?
Water can actually come out of magma itself, as well.” Volcanoes have also helped create a large portion of Earth’s atmosphere, she added. Fertile soil is another advantage of volcanic activity. Volcanoes also provide a good environment for the formation of new habitats for animals, plants and insects, she said.
How are mountain useful to us Class 6?
(d) Mountains are useful to man in various ways: Mountains are a storehouse of water. Water from the mountains is also used for irrigation and generation of hydro-electricity. Several sports like paragliding, hang gliding, river rafting and skiing are popular in the mountains.
What are the advantages of mountain Class 6?
Mountains are a storehouse of water that can be harnessed for the use of people. Many rivers have their source in the glaciers in the mountains. Water from the mountains is also used for irrigation and generation of hydroelectricity. The river valleys and terraces are ideal for the cultivation of crops.
What is the importance of mountains Class 6?
Mountains are a storehouse of water, and the glaciers in mountains are the source of many rivers. Water reservoirs are built in mountains and the water is used to irrigate fields and to generate power. River valleys and terraces are ideal to cultivate crops, and a variety of flora and fauna are also found in mountains.
Can extinct volcanoes erupt?
Volcanoes are classified as active, dormant, or extinct. Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.
Is Obsidian a real thing?
obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite. Obsidian has a glassy lustre and is slightly harder than window glass.
What is the difference between magma and lava?
Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.
