Do volcanic eruptions affect climate?
Do volcanic eruptions affect climate?
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.
Do volcanoes cause warming or cooling?
When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.
What causes the heat in a volcano?
With volcanoes, magma ascending in volcanic conduit also heats up and this helps them foam and erupt explosively.” They found that friction causes a substantial amount of heat between two rocks which melts the rock and makes it foam.
How do you get rid of volcanic ash?

How fast can volcanic ash travel?
50 miles an hour
Where is the safest place to be during a volcanic eruption?
Avoid low-lying areas, areas downwind of the volcano, and river valleys downstream of the volcano. Debris and ash will be carried by wind and gravity. Stay in areas where you will not be further exposed to volcanic eruption hazards.
How do I get rid of ash in my house?
Ash Removal from the Inside of Buildings and Households
- Cleaning by blowing with compressed air or dry sweeping should be minimized.
- A dustless method of cleaning such as washing with water and an effective detergent/wetting agent is recommended.
How do you clean up ash from a wildfire?
In most cases, gently sweeping indoor and outdoor hard surfaces followed by wet mopping is the best way to clean up ash residue. A damp cloth or wet mop may be all that is needed on lightly dusted areas. Avoid washing ash into storm drains whenever possible.
