The Cycling of Matter
Every time you take a drink, shower, or flush the toilet, does the earth’s freshwater become
less and less??
Every time you take a breath, is there less and less oxygen in the world??
NO!! Matter changes form, but does NOT disappear!!
Matter, such as oxygen, water, carbon, nitrogen CYCLE throughout a community.

Frozen Carbon
Perennially frozen ground, known as permafrost, underlies nearly a quarter of the Northern Hemisphere and stores a huge amount of
carbon

ANCIENT PLANTS removed carbon from
the atmosphere by absorbing carbon
dioxide. When the plants died, much of
their stored carbon was trapped and
frozen in layers of soil and glacial silt
OVER THOUSANDS OF YEARS the layers
of soil and debris built up to form a deep
layer of continuously frozen ground,
called permafrost, which now contains
twice as much carbon as the entire
atmosphere
CARBON ESCAPES when organic material in permafrost thaws and decomposes. Carbon dioxide is
released in aerated areas, but in lakes and wetlands carbon bubbles up as methane, an especially
potent greenhouse gas.
