1. Pyroclastic debris: This refers to fragmented solid material ejected during an eruption, ranging from fine ash and dust to larger bombs and blocks.
2. Ash and dust: These are fine particles of pulverized rock and glass ejected from the volcano. They can travel long distances and pose significant hazards.
3. Nitrogen compounds: Volcanic gases typically contain significant amounts of nitrogen (often as N2), along with smaller amounts of nitrogen compounds like ammonia (NH3). So, nitrogen compounds are among the gaseous products.
4. Sulphur compounds: Sulphur dioxide (SO2) and hydrogen sulphide (H2S) are common and often abundant volcanic gases. These compounds can have significant environmental impacts, including contributing to acid rain and atmospheric aerosols.
Therefore, all four are products of volcanic eruptions.
