![]() Information society is seen as a successor to industrial society. Some of the markers of this steady change may be technological, economic, occupational, spatial, cultural, or a combination of all of these. This is one of many dozen internet terms that have been identified to suggest that humans are entering a new and different phase of society. Mossberger as “Those who use the Internet regularly and effectively”. The people who are able to partake in this form of society are sometimes called either computer users or even digital citizens, defined by K. Proponents of this theory posit that these technologies are impacting most important forms of social organization, including education, economy, health, government, warfare, and levels of democracy. Its main drivers are information and communication technologies, which have resulted in rapid growth of a variety of forms of information. The pull of Earth’s gravity is so small here that molecules of gas escape into outer space.An information society is a society where the usage, creation, distribution, manipulation and integration of information is a significant activity. The uppermost layer, that blends with what is considered to be outer space, is the exosphere. Solar radiation makes the upper regions of the thermosphere very hot, reaching temperatures as high as 2,000☌ (3,600☏). ![]() Not much is known about the thermosphere except that temperatures increase with altitude. The thermosphere is located above the mesopause and reaches out to around 600 kilometers (372 miles). The atmosphere is thin here, but still thick enough so that meteors will burn up as they pass through the mesosphere-creating what we see as “shooting stars.” The upper boundary of the mesosphere is called the mesopause. In fact, the coldest temperatures in the atmosphere are near the top of the mesosphere-about -90☌ (-130☏). Temperatures decrease in the mesosphere with altitude. Above that is the mesosphere, which reaches as far as about 85 kilometers (53 miles) above Earth’s surface. The top of the stratosphere is called the stratopause. ![]() This ozone absorbs some of the incoming solar radiation, shielding life on Earth from potentially harmful ultraviolet (UV) light, and is responsible for the temperature increase in altitude. A high concentration of ozone, a molecule composed of three atoms of oxygen, makes up the ozone layer of the stratosphere. Temperatures in the stratosphere increase with altitude. It reaches from the top of the troposphere, which is called the tropopause, to an altitude of approximately 50 kilometers (30 miles). The stratosphere is the next layer up from Earth’s surface. Temperatures in the troposphere decrease with altitude. Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere-explaining why most of Earth’s clouds are located in this layer. The majority of the mass of the entire atmosphere is contained in the troposphere-between approximately 75 and 80 percent. The troposphere is thickest at the equator, and much thinner at the North and South Poles. The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The atmosphere is divided into five different layers, based on temperature. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent. Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. While oxygen is necessary for most life on Earth, the majority of Earth’s atmosphere is not oxygen. Not all scientists agree where the actual upper boundary of the atmosphere is, but they can agree that the bulk of the atmosphere is located close to Earth’s surface-up to a distance of around eight to 15 kilometers (five to nine miles). After that, the atmosphere blends into space. The clouds you see in the sky, the wind that is moving the trees or the flag in your school yard, even the sunshine you feel on your face-these are all a result of Earth’s atmosphere.Įarth’s atmosphere stretches from the surface of the planet up to as far as 10,000 kilometers (6,214 miles) above.
