Why does clearing forests using fire contribute to the greenhouse effect
Clearing forests using fire releases large amounts of carbon dioxide into the atmosphere, which is a major contributor to the greenhouse effect. The burning of trees and other organic matter releases carbon dioxide, which traps heat in the atmosphere and contributes to global warming.

Responses
Burning trees returns stored nitrogen to the atmosphere as nitrous oxide.
Burning trees returns stored oxygen to the atmosphere as a gas.
Burning trees returns stored carbon to the atmosphere as carbon dioxide.
Burning trees returns stored methane to the atmosphere as a gas.
Burning trees returns stored carbon to the atmosphere as carbon dioxide.
What is the main reason why raising cattle contributes to global warming?(1 point)
Responses
The main reason why raising cattle contributes to global warming is because cows produce methane gas, a potent greenhouse gas that has a much greater warming effect than carbon dioxide. Additionally, cattle ranching also contributes to deforestation, which further exacerbates the effects of climate change.

Responses
Cattle have microbes in their stomach that produce methane during digestion
Cattle store nitrogen, which is released as nitrous oxide as they die.
Cattle eat grass, which reduces the amount of plants that remove atmospheric carbon dioxide.

The Earth's carbon cycle diagram illustrates how carbon dioxide moves and interacts through the different spheres of the planet including the biosphere (plants), lithosphere (ground), atmosphere (air), and hydrosphere (water). Specifically, plants in the biosphere take in carbon dioxide through photosynthesis, which cycles carbon to other living organisms. Also, carbon dioxide moves from the atmosphere and dissolves in the oceans, impacting carbon's movement in water bodies. Moreover, the lithosphere acts as a carbon sink, storing carbon in rocks and soils, while releasing it back to the atmosphere by volcanic activity. These interactions demonstrate the importance of maintaining a balance in the carbon cycle to ensure a sustainable climate.
