This is so awesome – an animated water fountain. Totally amazing! Duration [...] I have a picture of an empty greenhouse and I must fill it in with pictures and explanations of the things needed to run it. Can someone help me by suggesting things I need and their uses. For example an ac heating system, I know one is needed but I don’t exactly know how to explain what it would do. The same goes for solar panels, I know they could help power the greenhouse, but I can I explain that in a more comprehensible way? A gas heating system is useful as, as well as providing warmth it also provides carbon dioxide for the plants. Continue reading What things are needed to run a greenhouse? Also, could you please list the most abundant types of greenhouse gases. Thank you. What is the carbon cycle and what does it have to do with energy and the greenhouse effect? The Earth’s average surface temperature of 15 °C (59 °F) is about 33 °C (59 °F) warmer than it would be without the greenhouse effect.[2] Global warming, a recent warming of the Earth’s lower atmosphere, is believed to be the result of an enhanced greenhouse effect due to increased concentrations of greenhouse gases in the atmosphere. In addition to the Earth, Mars and Venus have greenhouse effects.The Earth receives energy from the Sun in the form of radiation. Most of the energy is in visible wavelengths and in infrared wavelengths that are near the visible range (often called "near infrared"). The Earth reflects about 30% of the incoming solar radiation. The remaining 70% is absorbed, warming the land, atmosphere and oceans. |
