Greenhouse Affect

The greenhouse affect starts with the Sun. When the Sun hits the Earth the heat can either soak into the Earth or it can bounce off it and into the atmosphere. The greenhouse gases could absorb the heat in the atmosphere and the heat could make Earth warm enough so things can live on Earth. Examples of greenhouse gases: carbon dioxide, methane, nitrous oxide, and other gases. Many bad things can happen if too much heat gets in the air, though. source:accesories in paint for pictures

Climate Change Climate change is when the climate changes during a certain period of time. An example is turning seasons between summer to winter to fall to spring.

Climate zones I realized that climate zones are



3 Reasons Global Warming Reflection Global Warming is how the Earth heats up. It is when the heat hits the Earth and the greenhouse gases absorb it. In the activity, I learned what causes global warming. One reason, is that carbon dioxide gets released into the air by humans. Another reason, is when methane gets released into the air by humans. Also, when deforestation happens then fossil fuels can get into the air.( deforestation- when people cut down trees) Finally, I learned that when the heat emittes into the air then the greenhouse gases can absorb the heat and it can get trapped in the atmosphere. I watched a video and I used my knowledge based on that. I know that there is an electric car that someone invented and it saves less gas. It uses half gas, half electricity. I hope that they build more of those and that more people will use them so the temperatures do not reach so high. I hope that people invent new things that involve using less greenhouse gases.Global Warming can affect our lives in our ecosystem in different ways than other places but they are still bad effects. Some examples of bad effects in our ecosystem are because if the Earth gets heated up bad things can happpen. (look at examples on is global warming real reflection)

Is Global Warming Real Reflection I think that global warming is real. I read an article about how people know how temperatures were higher over time. They have different ways of doing it like looking at the rings of a tree and using a tool to dig up sediments from the ocean. I also believe that when humans burn fossil fuels that it is warmer because of the factories have smoke come out of them, right? Cars have steam come out of them, right? The steam probably has some of the greenhouse gases in it so then the steam goes into the air and then it probably makes the days warmer. There are different causes of global warming that are really bad like more misquitoes(cause of malaria), droughts, more precipatation, and higher risk of extinction for animals, and more bad causes. source:picture of causes of global warming and articles

humans affecting global warming vs. natural cause It seems like people might agree that humans are causing the Earth to warm up. Some people might agree that it is a natural cause. Some people think it is both! Which answer is it? I think it is both. I believe that humans are causing global warming, mostly because of fossil fuels. I also think it is a natural cause by the way that there is a cycle.I am pretty sure that there is no proof exactly but you might find some evidence, like from the last section.(is global warming real reflection)

Causes in our environment in global warming I looked on a picture of causes of global warming, I found what could happen in our ecosystem examples: changes in precipitation, increase of disease, changing range of disease, heat waves, droughts, water shortages, change in precipitation.

What are humans doing to reduce global warming? It seems like not a lot of things. If we could get the whole society to join us then we might make some of the heat go down! I want people to start using less fossil fuels as one thing! It seems like a lot of fossil fuels are burned each day! If we could reduce how much fossil fuels we use a day then the temperatures might start decreasing!

3 ways that you could help global warming (1) You could recycle more (2) You could use less electricity in buildings and other places (3) Instead of driving places, walk or bike to school / If you could invent a car that uses less greenhouse gases, then use that It seems to me that people do not usually make a change to help global warming, and that they recognize it, but they do not do much about it. I know saving electricity was known probably more than saving greenhouse gases, but when you save electricity you are saving energy, so I think people should still countinue that thing. Also, recycling was known too. I think that people did not consider it as helping our Earth stay cooler, though. I think that people knew some of the things, but they just did not think of it as keeping the Earth stay cooler.

Glossary global warming- process by which Earth heats up (by humans or natural) climate zones- different areas of climate greenhouse affect- (process explained under title greenhouse affect) (1) Sun (2) rays bounce off into atmosphere or soak in Earth (3) global warming happens (see picture of greenhouse affect) greenhouse gases- gases that absorb heat in atmosphere( look at picture and look under the title of the greenhouse affect) climate change- when the climate/ weather changes(seasons) carbon dioxide- main greenhouse gas known to cause the greenhouse affect methane- " " deforestation- when people cut down trees recycling- when items can get used again wind power- wind that is used to make power instead of other devices environment- the surroundings of something

My thoughts / Reflection In the beginning of the global warming process I am glad I looked at another persons wiki! I looked at Graces wiki first and I saw that the greenhouse gases absorb the heat in the air to make Earth warmer. I thought that the greenhouse gases trapped the heat but they actually absorb it. I looked on the other resources and I figured out that Grace was right! I learned to read more carefully and to check other peoples wikis. On the pictures I spent A LOT af time on them. I realized that you can only have two pictures on my wiki page. When I finally got it I was happy! On the greenhouse gases, I wonder how many there are? I want to do reseach and find out how many there are. It shows one category as other so I wonder how many other greenhouse gases there are total and in other? Look at the powerpoint for more information on global warming and how to save it by saving electricity.
