What happens when the atmosphere interact with the biosphere?
The interaction between the biosphere and the atmosphere affects all living organisms, including humans. The exchange of carbon (CO2) between the biosphere and atmosphere, and deposition of nutrients and heavy metals to the plant or ground surface are also important areas of research. …
Which gas is cycled into the atmosphere at the arrow?
Respiration in plants returns carbon dioxide to the atmosphere; an arrow shows this process.
How is carbon added to the atmosphere?
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
How is carbon stored in the atmosphere?
Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils; (4) in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite and …
Which three gases are released into the atmosphere when volcanoes erupt?
Volcanic eruptions emit water vapor and toxic gases into the atmosphere. Learn about the gases emitted from an erupting volcano, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid and carbon monoxide and their effects in this video lesson.
Why are volcanoes dangerous to humans?
Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
Is Vesuvius safe?
