Carbon Cycle and Climate Change

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms. It involves processes such as photosynthesis, respiration, decomposition, and combustion.

How does ocean acidification affect marine life?

Back

Ocean acidification, caused by increased CO2 absorption, decreases the pH of ocean water, harming marine organisms that rely on calcium carbonate for their shells and skeletons.

Front

What are the primary greenhouse gases contributing to climate change?

Back

The primary greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. They trap heat in the atmosphere, leading to global warming.

Front

What is the impact of deforestation on carbon dioxide levels?

Back

Deforestation leads to an increase in atmospheric CO2 levels because trees absorb CO2 during photosynthesis. When trees are cut down, this carbon is released back into the atmosphere.

Front

What is the significance of the northern latitudes in climate change?

Back

The northern latitudes have experienced some of the strongest and earliest impacts of global warming, including rising temperatures and melting ice.

Front

What role do marine organisms play in the carbon cycle?

Back

Marine organisms, such as phytoplankton, absorb CO2 during photosynthesis, and some, like corals, use carbonate to build their structures, thus playing a crucial role in the carbon cycle.

Front

What is the relationship between temperature and CO2 levels?

Back

Higher levels of CO2 in the atmosphere are associated with increased global temperatures, as CO2 is a greenhouse gas that traps heat.

Front

What is the effect of climate change on weather patterns?

Back

Climate change can lead to more extreme weather patterns, including increased frequency and intensity of storms, droughts, and heatwaves.

Front

How does the melting of polar ice caps affect sea levels?

Back

The melting of polar ice caps contributes to rising sea levels, which can lead to coastal flooding and loss of habitat.

Front

What is photosynthesis and its role in the carbon cycle?

Back

Photosynthesis is the process by which plants convert CO2 and sunlight into glucose and oxygen, playing a vital role in removing CO2 from the atmosphere.
