Detailed explanation-1: -Answer: When a volcano erupts particles of rock and ash are released into the atmosphere after this water droplets form around? When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain.

Detailed explanation-2: -Let’s look at a couple of examples of how a change in one system (or sphere) affects other Earth systems. Volcanoes (geosphere) erupt, sending ash and gases into the air (atmosphere) and sending lava and ash down onto surrounding forests (biosphere) and human habitations (biosphere).

Detailed explanation-3: -Volcanic ash is a mixture of rock, mineral, and glass particles expelled from a volcano during a volcanic eruption. The particles are very small-less than 2 millimeters in diameter.

Detailed explanation-4: -The volcano interacts with the 4 systems of Earth, the biosphere, the hydrosphere, the atmosphere, and the geosphere. When a volcano erupts, a mixture of gases are sent to the atmosphere. Some reflect the sun away from the earth, causing a cooling effect.

Detailed explanation-5: -Volcano » geosphere » hydrosphere » biosphere Volcanoes (events in the geosphere) may release a substantial amount of hot lava (geosphere), which causes mountain glaciers (hydrosphere) to melt. Mudflows (geosphere) and flooding may occur downstream from volcanoes and may inundate streamside communities (biosphere).
