Why are atmospheric carbon dioxide levels significantly lower in summer than in winter in a deciduous forest?
During the summer, deciduous trees undergo photosynthesis where they take in carbon dioxide to produce energy. This process helps to lower the atmospheric carbon dioxide levels. In winter, when the trees are dormant and not actively photosynthesizing, there is less carbon dioxide being absorbed, leading to higher levels in the atmosphere.
How do people know that greenhouse gases are being emitted?
Using carbon dioxide as an example: * Measurement of atmospheric carbon dioxide show a progressive increase * Calculations from the amount of fuel consumed indicate that CO2 is being generated, the gas is not being contained, removed or colected. It must therefore be being emitted
How do stalactites relate to Earth Science?
By being geological features, formed naturally from the mineral calcite by rain-water and atmospheric carbon-dioxide!
The substance which changes from solid to vapour state at normal atmospheric pressure without being liquified is?
One substance that does that is carbon dioxide.
What is being reduced that can absorb carbon dioxide?
As more forest is being reduced that can absorb carbon dioxide.
How does photosynthesis reduce carbon levels?
Photosynthesis reduces atmospheric carbon dioxide by using it as a reactant in a chemical reaction to create stored energy in autotrophic organisms. This is part of the reason environmental activists are trying to prevent forests being cut down - the forests can help mitigate some of the effects of increased atmospheric carbon dioxide and put a slightly brake on global warming.
Why solid carbon dioxide can never be wet?
At normal atmospheric pressure, carbon dioxide goes directly from the solid phase to the gas phase without ever being a liquid in between. The technical term for this is "sublimation." It is possible to have liquid carbon dioxide at higher pressures, so strictly speaking it's not true to say that solid carbon dioxide can never melt ... it just doesn't happen at normal pressures.
What role of potassium hydroxide in a volumeter in respiration experiment?
Potassium hydroxide in a volumeter is used to absorb carbon dioxide produced during respiration. This helps to ensure that the volume of gas being measured is only the oxygen consumed and not affected by the carbon dioxide produced. Potassium hydroxide reacts with carbon dioxide to form potassium carbonate and water, effectively removing carbon dioxide from the system.
Which reactant of photosynthesis is reduced?
In photosynthesis, the carbon dioxide molecules are being reduced, while the water molecules are being oxidized In photosynthesis, the carbon dioxide molecules are being reduced, while the water molecules are being oxidized
Do oxygen and hydrogen and carbon dioxide weigh the same?
No, oxygen, hydrogen, and carbon dioxide do not weigh the same. They have different atomic masses, with oxygen being heavier than hydrogen and carbon dioxide being heavier than both oxygen and hydrogen.
Why is more carbon dioxide being produced?
More carbon dioxide is being produced primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming.
What is the use of carbon dioxide?
used by plants and trees to be turned into oxygen.
