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 eruption of Krakatoa in 1883 caused one of the largest and most violent volcanic events in recorded history. The eruption and resulting tsunamis and atmospheric effects led to the deaths of over 36,000 people. The explosion also caused significant global climate effects, including changes in temperature and weather patterns.
Viscosity refers to a fluid's resistance to flow; fluids with high viscosity are thicker and flow more slowly. Volcanic eruptions, on the other hand, involve the expulsion of magma, gases, and ash from a volcano. Viscosity can affect the explosiveness or effusiveness of a volcanic eruption, as more viscous magmas typically lead to more explosive eruptions.
Magma with high silica content
No. A magma chamber is the area under a volcano where molten rock is stored. A caldera is a depression in the ground formed during an exceptionally violent volcanic eruption. A caldera forms when a volcano drains a large volume of magma from the magma chamber, causing the volcano to collapse into the space left behind.
The most likely combination to result in a violent volcanic eruption is the presence of highly viscous magma (such as rhyolitic or andesitic magma) and a large amount of dissolved gas (particularly water vapor and carbon dioxide). These conditions can lead to a buildup of pressure within the magma chamber, causing a violent and explosive eruption. Other factors such as the presence of a vent or conduit for the magma to reach the surface and the structural weakness or faults in the volcano can also contribute to the severity of the eruption.

The eruption of Mount Mazama that formed Crater Lake was a caldera forming eruption. This is the most violent type of volcanic eruption.
Only the most violent volcanic eruptions feature a pyroclastic flow.

· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
The most violent type of volcanic eruption among those listed is the Plinian eruption. Plinian eruptions are characterized by high eruption columns, massive ash plumes, and volcanic explosivity index values of 4 or 5. These eruptions are named after Pliny the Younger, who described the eruption of Mount Vesuvius in 79 AD.
