When a volcano erupts, it releases many gasses into the air, but most of it is water vapor. Other gasses include CO2 and hydrogen. Also an interesting side note, if you Google "volcanic lightning" you will see that the lightning produced by volcanoes is a different color than regular lightning. This is because lightning is produced within the different gasses (other than oxygen, which is blue lightning).
Yes, a change in the volume of volcanic rock formed at mid-ocean ridges can influence sea level. When more volcanic rock is created, it can displace seawater, potentially causing a rise in sea level. Conversely, if volcanic activity decreases and less material is formed, it could lead to a drop in sea level due to reduced displacement. However, these effects are relatively small compared to other factors influencing sea level, such as thermal expansion of water and melting ice.
The planet's internal heat is the fundamental property that has the greatest effect on its level of volcanic and tectonic activity. This heat comes from the planet's formation, radioactive decay of elements, and gravitational energy. The internal heat drives the movement of tectonic plates and leads to volcanic activity.
A seamount is an underwater mountain formed by volcanic activity, while a volcanic island is a landmass that rises above the ocean's surface due to volcanic eruptions. Seamounts can eventually grow to become volcanic islands if the volcanic activity continues and brings the seamount above the water level.
The internal temperature and composition of a planet's core have the greatest effect on its level of volcanic and tectonic activity. A planet with a hot, molten core is more likely to experience frequent volcanic eruptions and tectonic plate movement. Additionally, a planet's size and distance from its star can also influence its geological activity.

Long Valley Caldera's current volcanic activity level is normal with aviation color code of green. (Updated 2-9-12 CalVO) This simply means that there is no out of the ordinary activity currently present in the Long Valley Volcanic Complex. For further information on the Long Valley Volcanic System as well as its monthly activity updates see the CalVO (California Volcano Observatory) website in the related links section.
The composition of the Earth's mantle and lithosphere, as well as the amount of heat within the Earth's interior, are fundamental properties that have the greatest effect on volcanic and tectonic activity. The presence of magma chambers, subduction zones, and plate boundaries also play a significant role in determining the level of volcanic and tectonic activity in a region.
The level of gases in the air can be affected by human activities such as burning fossil fuels and industrial processes, as well as natural factors like volcanic eruptions and wildfires. Land use changes, deforestation, and agricultural practices can also contribute to changes in the levels of gases in the atmosphere. Climate change can further impact the composition of gases in the air, leading to potential feedback loops and further changes in atmospheric conditions.
Atolls are formed from volcanic islands that gradually sink below sea level due to subsidence. The process begins with the volcanic island's formation above the ocean surface through volcanic activity. Over time, as the volcanic activity wanes, the island gradually subsides below sea level, leaving a ring-shaped coral reef, or atoll, surrounding a central lagoon.
Mountains on the ocean floor that rise above sea level and form volcanic islands are called seamounts. These seamounts are formed by volcanic activity and can eventually emerge from the water to become volcanic islands.
An island can change through natural processes such as erosion, volcanic activity, and sea level rise. Human activities such as deforestation, development, and pollution can also significantly alter an island's landscape and ecosystem. These changes can impact the biodiversity, coastal areas, and overall sustainability of the island.
Mount Pelée in Martinique is considered to be dormant. There is no current activity or signs of volcanic unrest. However, it remains a potentially dangerous volcano given its history of explosive eruptions in the early 20th century.
