Greenhouse Effect PPT and PDF Free Download

Greenhouse Effect PPT and PDF Free Download: Generally, a physical property of the atmosphere of earth is referred to by an expression called greenhouse effect; if there is an absence of atmosphere then the temperature of the earth will be -18 degrees Celsius. Greenhouse gases absorb infrared radiation balance of energy of the planet gets damage and along with this, there will be dissimilarity in temperature.

During present state, the atmosphere system of our planet maintains a balance in taking of solar radiation by emitting radiations of infrared in the balance. Detailed explanation about a balance of atmosphere system is done in the following figure:

Fig1: Balance of atmosphere in radiation

Greenhouse gases absorb some amount of infrared radiation and re-emits it, a result of this feature warms the atmosphere’s surface, its lower layers and keeps surface 33 degrees Celsius warmer. The traveling paths of the radiations are very clearly explained in the diagram; 343Wm^-2 is the amount of incoming solar radiation, earth reflects some amount of infrared radiation and in this greenhouse gases absorbs some of the infrared radiations, 103Wm^-2 of solar radiation. Thus, a net amount of incoming solar radiation is 240Wm^-2 and a net amount of outgoing infrared radiation is 240Wm^-2, in this way balance in an atmosphere is maintained.

Types of Greenhouse Gases:

The amount of greenhouse gases contains in the atmosphere is even less than 1%, levels of greenhouse gases are fixed between ‘sources’ which produce greenhouse gases and ‘sinks’ which ruin greenhouse gases. The levels of greenhouse gases are affected by human beings, as they launch modern sources or else have interference with sinks which are natural. Few important greenhouse gases which are present in the atmosphere are as follows:

• Carbon dioxide (CO2)
• Nitrous oxide (N2O)
• Ozone (O3)
• Methane (CH4)
• Chlorofluorocarbons (CFCs)

Characteristics of greenhouse gases are as explained below:

Trends in Greenhouse Concentrations:

Concentrations of greenhouse gases are very clearly explained in the below graphs:

1. Carbon dioxide (CO2): the below graph explains the concentration of carbon dioxide.

2. Methane (CH4): the below graph explains the concentration of methane.

3. Nitrous Oxide (N2O): a growth of nitrous oxide per year is explained in the below graph.

4. Chlorofluorocarbons (CFCs): concentration of chlorofluorocarbons is explained in the below graph.

Consequences of Increased Greenhouse Effect:

The consequences that arise due to increase in greenhouse effect are as below:

• Global warming
• A rise in sea level

1. Global warming: enhancement in a concentration of greenhouse gases causes a decline in outgoing radiations of infrared, due to these climatic conditions of earth changes in maintaining a balance between incoming radiations and outgoing radiations. Global warming is also a type of climatic change and the easiest way to rescue from this energy is by warming the lower layers of the atmosphere.
2. Rise in sea level: if global warming happens then sea level will increase due to different things and those are as follows:

• Initially, high temperature makes sea level enhance because of thermal expansion of water in the sea.
• The next thing because of which sea level increases is from melting of glaciers and ice sheets of continents like Antarctica and Greenland.

Potential Impact on Human Life:

Due to a greenhouse effect, parameters that act as a potential impact on human life are as below:

• Economic impact
• Effects on aquatic system
• Agricultural impact
• Effects on hydrological cycle
