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.
What is released into the atmosphere by the burning of fossil fuels? Carbon from coal combines with oxygen in the air to form carbon dioxide. This is a primary gas released during the burning of all fossil fuels. The oxidation reduction of hydr â¦ ocarbon chains of oil also result in the release of some water vapor at about equal volume to carbon dioxide.
