Admin Why do volcanoes cause cooling?
Volcanic stratospheric aerosols cool the surface by reflecting solar radiation and warm the stratosphere by absorbing terrestrial radiation. The variations in atmospheric warming and cooling result in changes in tropospheric and stratospheric circulation.
How do underwater volcanoes positively affect ocean life?
The decreasing summer-time ice melting and precipitation due to the volcano cooling enhance the salinity near the Greenland Sea, and further reduces static stability, which means more surface water sinks into the deep ocean.
Which of the following composers is maximum content of volcanic gases?
Water vapour is consistently the most abundant volcanic gas, normally comprising more than 60% of total emissions. Carbon dioxide typically accounts for 10 to 40% of emissions. Volcanoes located at convergent plate boundaries emit more water vapor and chlorine than volcanoes at hot spots or divergent plate boundaries.
What is its connection to magmatism?
Magmatism is the emplacement of magma within and at the surface of the outer layers of a terrestrial planet, which solidifies as igneous rocks. Volcanism is the surface expression of magmatism. Magmatism is one of the main processes responsible for mountain formation.
What is the name of the bird that lives in a volcano?

How does a volcano affect the weather on Earth?
Yes, volcanoes can affect weather and the Earth’s climate . Following the 1991 eruption of Mount Pinatubo in the Philippines, cooler than normal temperatures were recorded worldwide and brilliant sunsets and sunrises were attributed to this eruption that sent fine ash and gases high into the stratosphere, forming a large volcanic cloud that…
Is it possible for an extinct volcano to erupt?
Volcanoes are classified as active, dormant, or extinct. Active volcanoes have a recent history of eruptions; they are likely to erupt again. 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.
What are the benefits of a volcanic eruption?
Precious gems are also another benefit that volcanoes eruptions make available. Stones like pumice volcanic ash and perlite (volcanic glass) are all mined and used for various commercial uses.
How many people live near a volcano in the world?
More than 80 percent of the earth’s surface is formed due to the volcanic eruptions and deposits. One in 30 people lives in danger areas near to the Volcanoes.
