Yes. Large explosive eruptions can release large amounts of sulfur dioxide. This gas forms tiny droplets of sulfuric acid in the upper atmosphere, which reflect a portion of the sun's light back into space and reduce global temperatures.
Some of the earth's atmosphere was made from volcanic eruptions in the past and also when a comet struck earth like when the dinosaurs were alive it cooled down the planet.
Volcanic eruptions are common in some of the Earth's volcanic hot-spots.
Lava gets cooled by water and becomes land... Other than that I can't think of anything else that's good about a volcanic eruptions
volcanic eruptions
The sulfur cloud that comes out after a volcanic eruption covers the earth's atmosphere, stops much sunlight from reaching Earth, and makes the Earth colder by 2 to 3 degrees Celsius.

Volcanic ash is considered extrusive igneous rock because it forms from volcanic eruptions where magma is rapidly cooled and solidified on the Earth's surface. The fine particles of ash are ejected from the volcano and settle on the ground, eventually compacting to form a rock-like material.
Cooled liquid rock is known as magma when it is below the Earth's surface and as lava when it erupts onto the surface. As it cools, it solidifies to form igneous rocks like basalt or granite. This process can happen quickly, as in the case of volcanic eruptions, or slowly, within the Earth's crust.

Here are some volcano-related questions for science projects: How does the type of volcano affect the eruption style? What factors influence the frequency of volcanic eruptions? How do volcanic eruptions impact the environment and surrounding communities? Can volcanic eruptions be predicted accurately? What are the different types of volcanic rocks and how are they formed? How do volcanic eruptions contribute to the formation of new landforms? What role do volcanic gases play in the Earth's atmosphere and climate? How do scientists monitor and study volcanic activity to improve prediction and mitigation efforts? What are the similarities and differences between volcanic eruptions on Earth and other planets? How have volcanic eruptions shaped the history and development of human civilizations?
Water on early Earth is believed to have primarily come from cometary bombardment. Comets, composed of ice and rock, collided with the Earth and released water vapor that eventually cooled and condensed into liquid water. Additionally, water may have been outgassed from the Earth's interior through volcanic activity.
