Meteorologists study and educate people about the Earth’s atmosphere and weather. Many weather forecasters on television news programs are meteorologists, although others work in universities or in the private sector.Know More
Most meteorologists belong to the American Meteorological Society. Meteorologists study atmospheric conditions such as temperature, humidity, wind speed and air pressure to learn about the weather and make predictions. Meteorologists may work for a variety of industries, including those associated with travel, military operations, science or communications. Most meteorologists have advanced science degrees.
Meteorology is an ancient science, though humans can still only predict the weather a few days in advance with any degree of certainty. Even under relatively stable conditions, the intricacies of the Earth’s atmosphere can change the weather quickly and in unpredictable ways. For example, snow can quickly become freezing rain if the temperature climbs a few degrees.
Modern meteorologists make use of worldwide data and complex computer models to predict the upcoming weather. Usually, predictions are presented as probabilities. For example, a meteorologist cannot be sure that it will rain later in the week, but the computer models show that under similar conditions, rain occurs 10 percent of the time. Accordingly, the meteorologist would state that there is a 10 percent chance of rain.Learn more about Careers
The two most abundant gases in the Earth’s atmosphere are nitrogen and oxygen. The atmosphere contains approximately 78 percent nitrogen and about 21 percent oxygen. The Earth’s atmosphere also contains lesser amounts of other gases, such as argon, carbon dioxide, hydrogen and neon.Full Answer >
Scientists are people who use research and experiments to learn more about the natural world. Scientists use scientific methods to derive knowledge systematically, performing repeatable experiments to ensure that their conclusions are valid and accurate. Scientists must not only be highly educated with regard to math and science, but they also must possess impeccable research skills. Additionally, scientists must be effective communicators and creative problem solvers.Full Answer >
Atmospheric pollution, or air pollution, is the introduction of harmful particulates, biological molecules or chemical molecules into the Earth’s atmosphere. Air pollution can lead to disease and death in humans. It can also damage other living organisms such as plants and animals by affecting the air quality and oxygen content of the air.Full Answer >
Teaching has been considered a noble profession by people for various reasons, with one of the most common being that teachers help to educate future generations. More generally, some have described teachers as "agents of the future," because they help people acquire the skills necessary to take on new challenges and contribute to the world in meaningful ways.Full Answer >
