Question

Perturbation of which of the following cycles contributes most to global warming?
A. the global carbon cycle
B. the global water cycle
C. the global nitrogen cycle
D. All of these cycles contribute equally

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of global warming.
As we know, the Earth is continuing to warm up. This increase in temperature has many different effects that are causing concern around the world. Some of these effects include an increase in natural disasters due to increased rain and snowfall, coral bleaching events due to warmer ocean temperatures, and changes in plant life as a result of hotter weather conditions.

Complete step by step solution:
The global carbon cycle is the process by which CO₂ and other greenhouse gases are transferred between the atmosphere, Earth's surface, oceans, land ecosystems and soil. While it may seem complicated at first glance, the global carbon cycle is actually a very important part of our environment.
The global carbon cycle begins with emissions from human activity (such as burning gasoline or coal), which create pollution that absorbs sunlight energy and traps heat inside the earth's atmosphere. This causes temperatures to rise across the globe, leading to an increase in plant growth that Henrys Law predicts will release more CO₂ into the air through photosynthesis.
Therefore, the perturbation of the global carbon cycle contributes most to global warming.

Option ‘A’ is correct

Note:
The global carbon cycle is the process through which human activity and natural processes interact to produce, remove, and store CO₂ in Earth's atmosphere. Human activities that emit greenhouse gases (GHGs) such as emissions from automobiles, factories, and homes contribute significantly to climate change.
