THE SOLAR SYTEM

      Some information  about the Sun:

           The big burning ball of gas that holds nine major planets in orbit is not unlike many stars in the universe. The Sun makes up 99.86 percent of the solar system`s mass and provides the energy that both sustains and endangers us. Scientists have lately begun calling its tremendous outpouring of energy “space weather.” The Sun can be divided into three main layers: a core, a radiative zone, and a convective zone. The Sun`s energy comes from thermonuclear reactions (converting hydrogen to helium) in the core, where the temperature is 15 to 25 million degrees. The energy radiates through the middle layer, then bubbles and boils to the surface in a process called convection. Charged particles, called the solar wind, stream out at a million miles an hour. Magnetic fields within the sun slow down The radiation of heat in some areas, causing sunspots, which are cool areas and appear as dark patches. Sunspot activity peaks every 11 years. The next peak is due in 2000. During this so-called solar maximum, the sun will bombard Earth`s atmosphere with extra doses of solar radiation. The last peak, in 1989, caused power blackouts, knocked satellites out of orbit and disrupted radio communications. (See our special report on Sunspots.) Though NASA scientists aren`t predicting any record-setting space weather in 2000, the peak is expected to be above average. “It`s like saying we`re going to have a mild or cold winter,” says Dr. David Hathaway at NASA`s Marshall Space Flight Center. But as communications rely increasingly on satellites, there are more targets in the sky and more Significant consequences to any disruptions. And there may be more to sunspots than disrupted communications. An active sun, known to heat the Earth`s outer atmosphere, may also affect our climate. Scientists say a small ice age from 1645 to 1715 corresponded to a time of reduced solar activity, and current rises in temperatures might be related to increased solar activity. The Sun frequently spews plumes of energy, essentially bursts of solar wind. These solar flares contain Gamma rays and X-rays, plus energized particles (protons and electrons). Energy is equal to a billion megatons of TNT is released in a matter of minutes. Flare activity picks up as sunspots increase. The Sun`s charged, high-speed particles push and shape Earth`s magnetic field into a teardrop shape. The magnetic field protects Earth from most of the harmful solar radiation, but extreme flares can disable satellites and disrupt communication signals. The charged particles also excite oxygen and nitrogen in the atmosphere to create the aurora borealis, or northern lights. More solar radiation during the upcoming solar maximum means an increase in the aurora. Similar to a solar flare, a coronal mass ejection is a bubble of gas and charged particles ejected over several hours. It can occur with or without solar flares, and can also threaten Earth`s atmosphere. If you stood on the Sun, its gravity would make you feel 38 times more heavy than you do on Earth. But it`s kind of hot, so please don`t try it.

MY PLANS FOR THE FUTURE


My plans for the future

I'm a second year tudent of ecological faculty. My future profession is an ecologist. This profession is vеrу actually today. Nowadays people understand how important is to solve the environmental problems that endanger people's lives. The range of environmental problems is wide: pollution of atmosphere, climate changes, and depletion of ozone layer, freshwater resources, oceans and coastal areas, deforestation and desertification, the extinction of some animals’ species, biological diversity, biotechnology, health and chemical safety. Taking into account of these problems the activity of an ecologist includes the ecological and economical issues:

· the calculation of using energy, water, earth;

· the description of factory and its products;

· the characterization of industrial and household waste;

· the controlling emission of industrial waste;

· the definition of measures to protect the environment;

· the choice of a convenient place for industrial and residential buildings according to the ecological and economical issues;

· the measuring of pollution levels in water, soil and air.



2.An ecologist must need good knowledge of Ecology, Chemistry, Economics, mathematics, Industrial Ecology etc.

People who call themselves “ecologists” are generally involved in research, usually in the academic arena. Workers who apply ecological principles to environmental needs are foresters, soil scientists, wildlife biologists, and others.



3.As a study of living things, ecology is a subset of biology (see “Biologist”). It differs in that it 19s the study of systems of living things – an ecosystem. This is one of the more critical technical needs in the environmental field these days, as nature groups, industrialists, and wildlife lovers seek to preserve wild habitats and slow the extinction of endangered species.

In academic research, the trend is usually toward specializing in the ecology of one system (or even one organism in a system), whereas in the working world of wildlife preservation the need is usually for ecologists who can deal with varieties of systems.

4.The future ecologist should know a systems analytic perspective on our societies’ supply, transformation and use of energy and materials. The students should have knowledge, skills and tools which are necessary for work on the complex environmental issues. Therefore, the students should know how to analyze the environmental impact on the use of natural resources. This includes technological aspects of how to decouple the environmental impact on economic growth. It also include economic and management aspects of industrial systems, including the energy system.


5.On the completion of the programme the student should be a competent industrial ecologist; ready to have a position in industry or in a governmental office. More specifically, on completion of the programme the student should:

¨ understand environmental and resource issues,

¨ have skills in analysis and environmental management;

¨ have insights into social and industrial energy and material use, processes that drive and hinder technical development, and management techniques and policy instruments and etc...

If you want to contribute to the protection of the environment of a town or city, choose this profession and enter the Daghestan Snate University.

FOR FUTURE ECOLOGITS

Introduction into Ecology

You are welcome to my blog!  

 This beautiful Earth was given to us free of charge, all we had to do was respect and take care of it . Sadly there are those with destructive instincts , and we can clearly see the evidence of this.
See the difference between two videos and made some conclusions!
