• The Atmospheres of Earth, Venus, and Mars

  Volcanoes affect the atmosphere through the release of dust particles and gases that are thrown into the atmosphere during eruptions. The primary gas that the volcanoes emit is carbon dioxide ( ), and this is integral in a planet's carbon cycle.

• Global warming: how would carbon dioxide affect plants?

  134747 What effect would increased carbon dioxide have on plants? One of the most dramatic environmental changes today is the increase in carbon-dioxide levels in the atmosphere.

• Carbon Dioxide

  However, current research has determined that the present level of carbon dioxide in the atmosphere is about 390 ppm (NASA, 2012).

• Plant Fossil Preservation and the Importance of their Stomata Count

  When the atmosphere is carbon-dioxide-rich, like it is currently, plants have fewer stomata since each individual stoma will be able to bring in more carbon dioxide.

• Anthropogenic Climate Change

  Carbon dioxide can last for decades in the atmosphere. Moreover, deforestation removes trees that could take in carbon dioxide and help reduce global warming. These are human activities.

• Carbon imbalance in the natural environment

  Therefore, due to carbon emissions and to the buildup of carbon dioxide in the atmosphere, it has only been partially offset by carbon uptake by the oceans and by plants and soils on land.

• Venus and Earth are about the same size and mass, yet carbon dioxide is a major constituent of the atmosphere of Venus, while oxygen is much more abundant in the Earth's atmosphere. Explain why the atmospheres are so different.

  Venus appears to have suffered a 'runaway greenhouse effect' where the carbon dioxide in the atmosphere lead to an increased planetary temperature, which freed trapped carbon from the oceans, increasing the amount of carbon dioxide in the atmosphere,

• Photosynthesis: Carbon Dioxide and Water Converted into Glucose & Oxygen

  Before plants appeared, the earth's atmosphere was high in carbon dioxide but contained no oxygen. The present atmosphere, by comparison, is about 0.035% carbon dioxide and 21% oxygen - thanks to photosynthesis.

• Earth's early atmosphere

  carbon dioxide Oxygen was not present in the early atmosphere until the evolution of photosynthetic organisms that created oxygen during photosynthesis from water and carbon dioxide.
