Understanding greenhouse gases and Source

what is the main source of greenhouse gases
Greenhouse gases are gases in the atmosphere that causes the greenhouse effect. The actual gases naturally occurring in the environment, but can also arise as a result of human activity.

Greenhouse gases are the most numerous is the water vapor that reaches the atmosphere due to the evaporation of water from the sea, lakes and rivers. Carbon dioxide gas is the second largest. It arises from a variety of natural processes such as: volcanic eruptions; the breathing of animals and humans (who breathe in oxygen and exhale carbon dioxide); and combustion of organic material (such as plants).

Carbon dioxide can be reduced due to absorption by oceans and absorbed the plant to be used in the process of photosynthesis. Photosynthesis splits the carbon dioxide and release oxygen into the atmosphere as well as taking carbons atoms.

Water vapor
Water vapor is a greenhouse gas that occurs naturally and is responsible for most of the greenhouse effect. Water vapor concentrations fluctuate regionally, and human activity does not directly affect the concentration of water vapor unless local scale.

Carbon Dioxide
Humans have increased the amount of carbon dioxide released into the atmosphere when they burn fossil fuels, solid waste, and wood for heating the buildings, moving vehicles and generate electricity. At the same time, the number of trees that are able to absorb carbon dioxide increasingly diminish due to the encroachment of forests for timber or taken for the expansion of agricultural land.

Methane
Methane which is a major component of natural gas also include greenhouse gases. He is an effective insulator, able to capture 20 times more heat than carbon dioxide. Methane released during the production and transport of coal, natural gas, and petroleum. Methane is also produced from the decomposition of organic waste in landfills (landfill), can even be issued by certain animals, especially cows, as a by-product of digestion. Since the beginning of the industrial revolution in the mid-1700s, the amount of methane in the atmosphere has increased one and a half times as much.

Various Lake and Definition

Various Lake
Lake: basins occur due to natural events that hold and store the water that comes from rain water, springs or rivers
  • Amiktic Lake: a lake which is not suffered circulation, such as Lake which is covered by a layer of ice on a regular basis for many years
  • Delta Lake: a lake in terbentu River delta
  • Dimiktik Lake: a lake which is free its circulation twice a year, for example in spring and autumn as well as berstratifia
  • According to a certain layer of Kashi in the summer, and changing the layer with the reverse in winter
  • Lakes: Lake Distrofik ranged from 0.001 Micron start s/d 500 microns. Particles in the size of the tsb has a residence time of several seconds can even mencpai a couple of months in the air
  • Monomiktik Cold Lake: a lake with water temperature is never more than 4 derjat Celsius and only 1 period of circulation in summer i.e. at temperatures below 4 degrees Celsius.
  • Lake Monomiktik Lake temperature: hot water is never lower than 4 degrees Celsius, free in winter circulation at a temperature of 4 degree Celsius or above, on summer time-ply plated
  • Oligotrofik Lake: a lake which is only a few foods contain substances and typically contains dissolved O2 depends on large quantities without any trace of the stratification

The process of GREENHOUSE EFFECT

The process of GREENHOUSE EFFECT

This time I will explain briefly about the onset of a global warming.
When the solar radiation reaching the Earth's atmosphere, some heat will be reflected by the atmosphere in the form of infrared rays, and some will be passed on to the surface of the Earth. This causes the surface of the Earth is becoming warmer.

The surface of the Earth reflects back the heat and partially absorbed by the "greenhouse gases"--such as CO2, methane and NO atmosphere. This is the process that prevented irrespective solar heat into space.

The facts of GLOBAL WARMING

The facts of GLOBAL WARMING
Article on me this time, I will give a few facts about facts from the onset of global warming, among others, as follows:

The melting ice at the North and South poles
Increasing the level of the sea surface
Change weather/ilkim increasingly extreme
Heat waves are becoming increasingly ferocious
Endless glaciers of the world's fresh water resources

what is a greenhouse gas effect

what is a greenhouse gas effect
what is a greenhouse gas effect
Greenhouse effect (green House Effect) as long as it bears the negative predicate in the eyes of the community. The actual existence of the greenhouse effect on Earth, it's helpful to human survival. To find out what is the greenhouse effect should we know it used to be the origin of the term "greenhouse effect".

Green House or often meaning as the "House of glass" is the actually the House of glass (glass/plastic) which is also seen in green. Greenhouse in human designs to gardening in an area experiencing winter, cold weather disiasati by building a "House of glass". Plants in a greenhouse it will receive sunlight during the day, sunlight penetrating through the glass but the heat energy staying awake in the room which is designed because the energy is then trapped inside a greenhouse with the help of gas-GHG (greenhouse gasses), the temperature inside the greenhouse will be warmer than the outside temperature. This is analogous to the Green House Effect or the greenhouse effect. This home looks green from afar due to their greenery.

Greenhouse gases are gases that can absorb most of the energy of the radiation from the Sun and then removing/updating the emisikannya back. Some greenhouse gases are: water vapor (H2O), carbon dioxide (CO2), methane and ozone (O3). The gases already exists on the Earth, when the Earth was formed and contribute greatly to human life. The greenhouse effect is a natural effect that already occurred when the Earth began to form, the greenhouse effect helps to keep the average temperature of Earth's surface is still warm.

In a simple process of greenhouse effect is as follows:
Solar energy (which is made up of many penjang waves) before it reaches Earth has experienced by filtering layers which envelop the Earth (eksosfer, thermosphere, stratosphere ..), so that energy-hazardous energy (gamma rays, X-rays) are filtered and which reached its Earth energy is not higher than the energy of the UV-C (UV-A and UV-B is now starting to reach Earth because ozone layer which is "hollow", a discussion of ozone will be discussed later), it occurs naturally in all living beings so that it can live.

The energy that reaches the Earth is partially absorbed, partly reflected back into the atmosphere, the energy is absorbed and then again removed/in-emisikan to the surface in the form of radiation, surface and thermal infra-red. Infrared energy is then absorbed and released on an ongoing basis (continue) by greenhouse gases in the Earth's surface (water vapor, CO2, etc), thus making the surface of the Earth maintained warm.

The greenhouse effect and its relation to climate change (climate change) with regard to its high human activity and caused huge CO2 emissions on the Earth's surface, some of the causes of high CO2 emissions is the burning of petroleum (gasoline, diesel, etc.), logging/deforestation and the production of cement. The high concentration of CO2 is causing the temperature on the surface of the Earth is getting hot.

Before the rain sometimes we feel very hot weather, it is also associated with high air humidity (water vapor), water vapor is also one of the greenhouse gases which can absorb infrared energy and then take it off (emissions) back.
