Carbon Cycle – the continuous transfer of carbon between the atmosphere and living things.Just like water in the water cycle, carbon is renewed in the carbon cycle. Click on the picture to play the carbon cycle labeling game! Click here for carbon cycle videos.
Nitrogen Cycle – the way nitrogen moves between the air, soil, plants, and animals.Click on the picture for more Click on the picture for moreinformation. information.
groundwater – water that seeps in and is stored in the ground
watershed – an area on which water runs downhill to a common stream, lake, or river
runoff – water that moves across the land,heading for low places, and eventually, the ocean
composting – a process by which organicmatter like leaves, plant materials, food scraps and grass clippings breakdown to be used in the soil.The compost contains nitrogen, phosphorus, and potassium, which help enrich the soil.
raw materials – things that are usedto make products – wood, metals, sand, oil are all raw materials
inexhaustible resource – aresource, like the sun, that will not run out
renewable resource – a resource,like plants and animals, that can be grown, or produced to make more
nonrenewable resource – manyraw materials, such as oil and metals are non- renewable resources
