Water Cycle – the continuous movement of water between the Earth’s
surface and the air, changing from liquid to gas to liquid.
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.

water vapor – water in its gas state
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 organic matter 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 used to make products – wood, metals, sand,
oil are all raw materials
inexhaustible resource – a resource, 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 – many raw materials, such as oil and metals
are non-renewable resources
