Stuttering occurs when the natural flow of speech is interrupted. When the child involuntarily prolongs sounds, is unable to produce certain sounds, or repeats a sound, we can say he or she is at risk for stuttering. Stuttering will usually begin between the ages of three and six.
It is significant that so much carbon dioxide stays in the atmosphere because CO 2 is the most important gas for controlling Earthâs temperature. Carbon dioxide, methane, and halocarbons are greenhouse gases that absorb a wide range of energyâincluding infrared energy (heat) emitted by the Earthâand then re-emit it.
Carbon dioxide adds to the greenhouse gases that are warming the atmosphere. Carbon dioxide moves in and out of the atmosphere using the carbon cycle, from trees, oceans, soil and animal life.Extra carbon dioxide is now being added to the atmosphere by man burning fossil fuel, and by deforestation, removing forests that used to absorb and store carbon.arbon dioxide doesn't really hurt the atmosphere. Venus and Mars both have atmospheres comprised primarily of CO2. CO2 is also a necessary constituent of our atmosphere for â¦ plant respiration (photosynthesis) and for keeping the earth warm.
