1. Anthropogenic derived from human activities
2. Erosion The process by which wind, water, ice, or
gravity
transports soil and sediment from one
location to another
3. Runoff Part of the water cycle where an excess of
water runs
down and does not sink into the soil and
eventually makes it to the rivers, lakes, and
oceans.
4. Denitrification process in which fixed nitrogen compounds are
con-
verted back into nitrogen gas and
returned to the atmosphere
5. Nitrification ammonia (NH3) is converted to nitrate ions
(NO3)-
6. Amonification the part of the decomposition process where
nitrogen
in inorganic molecules reaction acids and
nucleotides is converted to ammonium
7. Nitrogen Fixation Process of converting nitrogen gas into
ammonia
8. Abiotic Non-living things
9. Biotic Describes living factors in the environment.

14. Biodiversity The amount of biological or living diversity per
unit
area. It includes the concepts of species
diversity, habitat diversity and genetic
diversity.
15. Divergent plates Two tectonic plates that are moving away from
each
other
16. convergent plates tectonic plates that collide with each other
17. Transform Plates Plates that are moving past each other (rubbing
next
to each other) in opposite directions
18. primary succession succession that occurs on surfaces where no
soil
exists
19. secondary succes- Succession following a disturbance that
sion destroys a community without destroying
the soil
20. logistic growth Growth pattern in which a population's growth
rate
slows or stops following a period of
exponential growth
21. logistic growth describes a population whose growth is
mod- el initially expo- nential, but slows as the
population approaches the carrying capacity
of the environment
22. exponential growth Population growth that is unhindered because
of the
abundance of resources for an ever-
increasing popu- lation.

23. exponential tells us that, under ideal conditions, the
growth model future size of the population depends on the
current size of the population, the intrinsic
rate of the population, and the amount of
time over which the population grows
24. intrinsic growth rate the maximum potential for growth of a
population
under ideal conditions with unlimited resources
