What else can I help you with?
What gases are Emitted during volcanism?
gases emitted during volcano eruptions are basically oxides of shulphur,etc
What do gases escape from?
Gases can escape from various sources such as industrial processes, natural events like volcanic eruptions, leaks from pipelines or storage tanks, and combustion of fossil fuels. It is important to monitor and mitigate these emissions to prevent environmental and health risks.
Do continental volcanoes contain water vapor and other gases?
Yes, continental volcanoes can release water vapor and various gases, such as carbon dioxide, sulfur dioxide, and hydrogen sulfide, during eruptions. These gases can contribute to the explosive nature of volcanic eruptions and their potential to impact surrounding environments.
What is the exit of the eruptions called?
The exit of volcanic eruptions is called a vent. This is the opening through which volcanic material such as lava, ash, and gases are released from the Earth's interior to the surface.
Scientists hypothesize that Earth's early atmosphere was formed primarily by gases released by?
Volcano Eruptions
Violent volcanic eruptions are common where magma has?
Violent volcanic eruptions are common where magma has a high gas content and viscosity. The pressure from trapped gases builds until it explosively releases, causing explosive eruptions like Plinian or Pelean eruptions. These eruptions often result in ash plumes, pyroclastic flows, and lahars.
Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
Earth's early atmosphere was formed by gases released by oceans plants cornet impacts or volcanic eruptions?
Earth's early atmosphere was primarily formed from gases released by volcanic eruptions. These gases included water vapor, carbon dioxide, nitrogen, and trace amounts of other gases such as methane and ammonia. Over time, the atmosphere evolved as oxygen levels increased due to the emergence of photosynthetic organisms like cyanobacteria.
Why are pilnian eruptions move violent then hawaiin eruptions?
Plinian eruptions are more violent than Hawaiian eruptions because they involve highly viscous magma that traps gas bubbles, leading to increased pressure buildup and explosive eruptions. In contrast, Hawaiian eruptions involve less viscous magma with low gas content, allowing the gases to escape easily and resulting in more effusive, less explosive eruptions.
What is the most abundant dissolved gas in magma?
The most common dissolved gas in magma is water vapor, or H2O. Other important gases that may be present in magma and released during volcanic eruptions are carbon dioxide, sulfur dioxide, and hydrogen sulfide.
One thing all volcanic eruptions have on common is that they emit large amounts of gas?
All volcanic eruptions release gases, including water vapor, carbon dioxide, sulfur dioxide, and hydrogen sulfide. These gases can contribute to air pollution, climate change, and acid rain.
Can eruptions eject debris and gases at supersonic speeds?
Yes, eruptions can eject debris and gases at supersonic speeds. During explosive volcanic eruptions, the rapid release of pressure can accelerate volcanic material to speeds that exceed the speed of sound. This can result in the formation of pyroclastic flows, which are dense, fast-moving clouds of ash, rocks, and other volcanic fragments.
