GEOLOGY

Detailed explanation-1: -Eruption of a large volcano on a tropical island releases ash and gases into the atmosphere. After the eruption, the air temperatures on the island cool temporarily before returning to normal. Which is the MOST likely reason for the temporary cooling of the island? Water vapor condenses and causes precipitation.

Detailed explanation-2: -Which is the MOST likely reason for the temporary cooling of the island? Fine particles of atmospheric dust block sunlight. The average temperature of the surface of Earth has increased approximately 1°C in the past century.

Detailed explanation-3: -Answer: Volcanoes release carbon dioxide (CO2) and other greenhouse gases when they erupt, which can lead to climate warming if the input of CO2 to the atmosphere is sufficiently large.

Detailed explanation-4: -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-5: -Volcanic eruptions play an important role in cooling the planet. The sulphur gases from the volcanic plumes combine with other gases in the atmosphere, and these aerosols scatter solar radiation, reflecting it into space.
