Document Summary
Environmental science chapter 2: science literacy and the process of science. Science gives us tools to observe the natural world. Since the 1970s, the ozone layers had thinned by a third during the antarctic spring. Observations: information detected with the senses or with equipment that extends our senses. Use observations to draw conclusions or make inference. Cfcs produce atmospheric chlorine these chemicals increased at the same rate as the depleting ozone. Replication within a study and between studies increase the reliability of the data. Ozone depletion connected to the increase chlorine compounds in the atmosphere. Atmosphere: blanket of gases that surrounds earth and other planets. Troposphere: region of the atmosphere that starts at the ground level and extends upward about 11 km (lowest level of the atmosphere) where weather occurs. Stratosphere: region of the atmosphere that starts at the top of troposphere and extends up to about 50 km contains the ozone layer much less dense than the troposphere.
