 Nonrenewable resources are considered to be fossil fuels and nuclear. United States rely on a lot of fossil fuels including coal, oil, and natural gas. We use these to create energy, but it destroys our atmosphere also. In return there are renewable resources like solar, wind, water, and biomass. The renewable resources are a lot better for the atmosphere and it is either direct or indirect with the sun. Solar is directly used to heat and light up homes or buildings. Wind turbines are used from the suns heat which creates the wind to move the turbines. Energy can change form through Earth Systems through internal or external sources of energy which both creates heat. Most of the changes are from the sun. The sun creates the heat which creates the Global Science.With the Earths surface and atmosphere heating up by the sun, the ocean currents and winds are created. The heat from the sun in transferred through the atmosphere by three mechanisms, Conduction, Convection, and Radiation. Radiation is the warm feeling on sunny days when you go outside and tan, have fun with friends, or play sports. The transfer of heat energy by electromagnetic waves is Radiation. The transfer of one subject to another is call Conduction. Copper or metal can be a conductor. When you take a piece of grass and set it on the electric fence and you get shocked. The grass is the conductor. The electric energy goes through the grass and into your body. A safety pin over the flame is the same way. The safety pin absorbs the heat and the molecules will transfer over to the hand holding it. The The rate of heat transferred determines how well a conductor is. A piece of grass wouldn't be the best conductor, metal or copper would be a better choice. Transfer of heat through the movement of water or air is Convention.

I worked on my final project for English and Digital Media. I need to get pictures and put them in a slide show. But it's difficult to find the ones I want.

Water Request

1. Water pollution is when bodies of water get contaminated. The different types of pollution are, surface water pollution, oxygen depleting, groundwater, nutrients, microbiological, suspended matter, and chemical. When oceans, rivers, and lakes get polluted it is called surface water pollution. When to much biodegradable material is added to the water then the number of microorganisms increase and use up the the available oxygen depletion. Pesticides cause groundwater pollution. Nutrients can be found in waste water and fertilizers, and these can cause excess weed and algae growth. Microbiological is natural water pollution by microorganisms. Suspended matter is when the pollution isn't able to be absorbed in water because the molecules are too big. Chemical pollution is from agricultural and industrial work that runs off into the water.
2. Point source is a single source and a non-point has many sources.
3. Three causes of pollution is underground leakage, sewage, waste water, and radio active waste.
4. Suspended particles can often reduce the amount of sunlight that reaches the water disrupting growth of plants.
5. To help improve pollution, turn off tap, don't throw paint oils down the sink, environment friendly house products, don't litter, plant more plants, septic tank, ozone waste water treatment.

Solar Energy

March: 332 kilowatt hours of energy was produced. 6 trees were saved and there 110,666.667 batteries.

April: 402 kilowatt hours of energy produced. 7 trees were saved and 134,000 batteries.

Today: 3.72 kilowatt hours of energy was produced.

Our solar panels are pretty cool. We don't learn much about them or get to see our solar panals so we don't know how well they work and how much energy it saves. I think we should put it more in class or even have a class about it.
