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.

Nitrogen Cycle – the way nitrogen
moves between the air, soil, plants, and
animals.

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
