Detailed explanation-1: -Volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. These particles serve as nuclei for the formation of water droplets (hydrosphere). Rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

Detailed explanation-2: -The geosphere affects the atmosphere as soil provides nutrients to plants that then release water vapor into the atmosphere. Volcanoes are another element in the geosphere that releases rocks, debris, and ash into the atmosphere when it erupts. Both examples mentioned also affect the other spheres.

Detailed explanation-3: -Injected ash falls rapidly from the stratosphere–most of it is removed within several days to weeks–and has little impact on climate change. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

Detailed explanation-4: -The geosphere impacts Earth’s climate in a variety of ways. Typically, the geosphere reacts on geologic timescales, affecting climate slowly and over millions of years. However, the burning of fossil fuels over the last 150 years has sped the impact of the geosphere on climate.

Detailed explanation-5: -When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth’s surface. That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones.
