There's also the small matter of a massive drill digging a hole in Seattle that released volcanic gases that turns people into zombies.

Not exact matches

Rocky planets like Earth, Mars and Venus gained their atmospheres as volcanic gasses like carbon dioxide and water vapor were released from the planets» interiors.

Gases released from smaller, nonexplosive volcanic eruptions tend to return quickly to the planet's surface.

Volcanic activity can spawn earthquakes or result in the release of steam or other gases before an eruption even occurs.

The only place on Earth that they are known to form is at fumaroles, volcanic vents that release hot gases.

Scientists now think that massive volcanic activity, in a Large Igneous Province called the Siberian Traps, raised air and sea temperatures and released toxic amounts of greenhouse gases into the atmosphere over a very short period of time.

Through these vents, volcanic activity in Earth's interior releases hot gases and dissolved minerals into the ocean and heats the water to temperatures of nearly 700 degrees Fahrenheit.

Scientists hypothesize that releases of toxic volcanic gases rendered the area's air and water lethal to most life in a short time.

Most of the lava's gases were released during the eruptions, but some of the gas remained trapped in crystals near the volcanic vents.

The findings rest on the widely held theory that Earth's atmosphere was formed by gases released from volcanic activity on its surface.

In Earth's past the trigger for these greenhouse gas emissions was often unusually massive volcanic eruptions known as «Large Igneous Provinces,» with knock - on effects that included huge releases of CO2 and methane from organic - rich sediments.

Currently, Arenal Volcano only releases gases in crater C and has fumarole activity in crater D. Seismic monitoring of the volcano indicates that volcanic activity remains low and external manifestations have been reduced to a minimum.

The other point about volcanic emissions: the majority of the activity is in the oceanic spreading zones, which release carbon into the water, but because it is absorbed by the water, the gas isn't released for some time, sometimes up to 1000 years.

Volcanic eruptions can release large amounts of climatically active gases.

Also, regarding subsea volacanic eruptions — a volcanic eruption involves release of magma at several thousand degrees C plus superheated gases — when that hits cold sea water you are going to have a very violent and explosive change of form from lquid water to steam combined with the release of dissolved gases (mostly CO2)-- I am not sure what laws of Chemistry and Physics you are looking at, but I would suggest that that those bubbles and heated gases and water will rise to to the surface very quickly and have a major local effect on any nearby ice.

One proposal is that volcanic activity releases greenhouse gases that eventually warm the planet back up.
