What happens during an eruption? 

When magma reaches earth's surface it is called lava. It may pour out in gentle streams called lava flows or erupt violently into the air. Rocks ripped loose from the inside of the volcano or torn apart by the gas may be shot into the air with the lava. These rocks blown out of avolcano are called pyroclastic rocks.

6. Does the sun have an effect on volcanism?

In the climate model, both the reduced output from the sun and the increased amount of volcanic aerosols{fine particles which reflect sunlight away from the earth and which are ejected into the stratosphere by volcanic eruptions} contribute a sizeable amount to the northern hemisphere cooling seen in temperature reconstruction, their relative importance depends upon uncertain estimates of exactly how much each changed relative to a century later.
