What is Global Warming?Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent
What Is The Greenhouse Effect?
Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is this gaseous outer ring and its misleadingly called greenhouse effect that makes life on Earth possible – and that could destroy life as we know it.
What are greenhouse gasses?
Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot. As a result people, animals, and plants would die because the heat would be too strong.
What causes global warming?
Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy.
Some other examples of using energy and polluting the air are:
1..Turning on a light
2..Watching T.V.
3..Listening to a stereo
4..Washing or drying clothes
5..Using a hair dryer
6..Riding in a car
7..Heating a meal in the microwave
8..Using an air conditioner
9..Playing a video game
10..Using a dish washer
When you do these things, you are causing more greenhouse gasses to be sent into the air. Greenhouse gasses are sent into the air because creating the electricity you use to do these things causes pollution. If you think of how many times a day you do these things, it’s a lot. You even have to add in how many other people do these things! That turns out to be a lot of pollutants going into the air a day because of people like us using electricity. The least amount of electricity you use, the better.
When we throw our garbage away, the garbage goes to landfills. Landfills are those big hills that you go by on an expressway that stink. They are full of garbage. The garbage is then sometimes burned. This sends an enormous amount of greenhouse gasses into the air and makes global warming worse.
Another thing that makes global warming worse is when people cut down trees. Trees and other plants collect carbon dioxide (CO2), which is a greenhouse gas.
Carbon dioxide is the air that our body lets out when we breathe. With fewer trees, it is harder for people to breathe because there is more CO2 in the air, and we don’t breathe CO2, we breathe oxygen. Plants collect the CO2 that we breathe out, and they give back oxygen that we breathe in. With less trees and other plants, such as algae, there is less air for us, and more greenhouse gases are sent into the air. This means that it is very important to protect our trees to stop the greenhouse effect, and also so we can breathe and live.
This gas, CO2, collects light and heat (radiant energy), produced by the sun, and this makes the earth warmer. The heat and light from the sun is produced in the center of the sun. (The sun has layers just like the earth.)
The dirty yellow color on outside is the surface. The light and dark yellow colored area is the convection zone. The orange colored area is the radiative zone, and the red colored area is the core. The squiggle lines represent radiant energy.
This layer is called the core. Just like a core of an apple, it is in the middle. Here there is a very high temperature, about 27,000,000°F. This heat escapes out of this layer to the next layer, the radiative zone. This layer is cooler, about 4,500,000°F. Gradually, the heat and light will pass through the convection zone at a temperature of around 2,000,000°F. When it gets to the surface, the temperature is about 10,000°F. Finally, the heat and light is sent into space. This is called radiant energy (heat and light). The radiant energy reaches the earth’s atmosphere. As a result of this process we get light and heat. When you pollute, you send chemicals into the air that destroy our atmosphere, so more heat and light cannot escape from the earth’s atmosphere.
What are people need to do stop global warming?
Remember one thing earth is the only place which makes us to live and it is our duty to save it. But am begging each one, please do the following things that will make our future to live in this world.
1) Kindly don't use your Vehicle for travelling short distance , better you take a walk which keeps your body and nature good.
2)The amount of Co2 release by an aircraft for a person for an hour is equals to the amount of Co2 release by an normal man per year. So you friends try to prevent travelling by air.
3) Turn-off your light, Refrigerators and other sources for pollution which listed above when you are moving out.
4)Try to plant trees around your home and protect them as your babies.
5)Peoples who are having cars, use it only for family trips and when you are going alone, better you use your two-wheeler Vehicle or Bus that will reduce pollution.
Kid can help stop global warming, too!!
Although adults do many things to help stop global warming, kids can do just as much. Kids can’t do hard things like making a law, but we can do easier things like not watching as much TV. You can listen to your parents when they say, turn off your lights or go play outside. Listening to them and actually trying to help can help you, your environment, and the world.
