Temperatures tend to fall as atmospheric particulate matter increases. This has been known from massive volcanic explosions, and a small handful of scientists some years back proposed a global thermonuclear war could potentially plunge earth into a "nuclear winter," or new ice age. We now know particulate settles out relatively quickly, so that the nuclear winter would only last 2-5 years.
Both the particulate and the hydrogen sulfide gas would have an immediate cooling effect. Volcanoes also emit CO2, which lingers in the atmosphere thousands of times longer than the particulate. So although the initial effect would be cooling, the long term effect would be a slight warming. A LOT of volcanoes could build up CO2 levels significantly over thousands of years.
At the present time humans release about 100 times the CO2 of all earth's volcanoes combined, according to the USGS.
Ash released from a volcanic eruption can enter the upper atmosphere where it can reflect sunlight. Volcanoes formed the early atmosphere of the planet, so they definitely can have global impact, an increase in agriculture does not signify a significant change in global temperature.
The Earth's early atmosphere was likely dominated by gases such as carbon dioxide and water vapor. Over time, volcanic activity and the emergence of photosynthetic organisms led to a decrease in carbon dioxide and an increase in oxygen levels. This process, known as the Great Oxidation Event, occurred around 2.4 billion years ago and shaped the atmosphere into its current composition.
Volcanic eruptions release large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which can contribute to global warming by trapping heat and increasing the Earth's temperature.
carbon dioxide would increase in the environment if there is an increase in the burning of fossil fuels, deforestation, industrial activities, or volcanic eruptions, as these processes release CO2 into the atmosphere.
Volcanic activity was the primary source of CO2 in the Earth's early atmosphere. During this time, volcanic eruptions released large amounts of gases, including carbon dioxide, into the atmosphere.

Volcanic dust and ash in the atmosphere can cause reduced visibility, air travel disruptions, and potential health hazards. They can also contribute to cooling of the Earth's surface by reflecting sunlight, leading to temporary climate effects.

Yes. Explosive volcanic eruptions release sulfur dioxide into the atmopshere. This gas forms tiny droplets of sulfuric acid in the upper atmosphere, which reflect some of the sun's warming rays back into space.
Volcanic eruptions release large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which can contribute to global warming by trapping heat and increasing the Earth's temperature.
Large volcanic eruptions release massive amounts of sulfur dioxide gas and ash particles into the atmosphere. Sulfur dioxide reacts with water vapor to form sulfuric acid aerosols, which reflect sunlight back into space and reduce the amount of solar radiation reaching the Earth's surface. This causes a cooling effect on the planet's temperature.

Mountains can both increase and decrease in size over time. Factors such as tectonic plate movement, erosion, and volcanic activity can lead to the growth or reduction of mountain size. Overall, the net effect of these processes determines whether a mountain increases or decreases in size.
yes if the debris reaches the upper atmosphere which would cloud out the sun.
