Assessment

3.  the study of the dynamics and
chemistry of the layers of gas that
surrounds the earth, other planets
and moons.
Examine the new phenomenology
of the earth gaseous outer layer
with emphasis upon interrelation to
the other systems.
It is an umbrella term for the study
of earth’s atmosphere, its
processes, and the effects other
systems have on the atmosphere.

4. Atmospheric Sciences
includes the following;
• Meteorology – study of
weather;
• Climatology – study of
climate;
• Aerology – study of the
atmosphere;

5. • the study of ecosystem
• focuses on the relationships
between living organisms and
their environment
• the term was coined by the
biologist Ernst Haeckel (1866)
2 Components
of Ecosystem
1. biotic
components –
the living
organisms
2. Abiotic
components-
non living
organisms

6. LEVELOF ECOLOGICALSTUDY
1. Organismal Ecology – study of individual
organisms behavior in response to
environmental challenges.
2. Population Ecology – study of factors that
affects and change the size and genetic
composition of population of organism.
3. Community Ecology – study of how
community structure and organization are
changed by interaction among living
organisms.

7. 4. Ecosystem Ecology – the study of entire
ecosystem.
5. Landscape Ecology – study the exchange
of energy materials, organisms and other
products of between ecosystem.
6. Global Ecology – study of the affects of a
regional change in energy and matter
exchange on the function and distribution of
organisms across biosphere.

8. BIOSPHERE - All
living components
of the Earth. All
plants animals and
microbes and their
surroundings are
known as
biosphere.

9. • the study of chemical
processes occurring in the
environment which are
imparted by humankind
activity.
• the interdisciplinary science
that includes atmospheric,
aquatic and soil chemistry.

10. Environmental
chemistists
-study the behavior of
pollutants and
their environmental effects
on the air, water and soil
environments, as well as
their effects on human
health and the
natural environment.

11. • the study of geology and
geochemistry in the natural
world, physical and human
geography and challenges
faced by communities and
cities and their solution.
• provides the knowledge,
experience, and ingenuity to
meet society’s demands for
natural resources,
environmental quality, and
resilience to hazards.

12. GEOSCIENCE includes the following;
Physical Geography- which
deals with the study of processes and
patterns in the natural sciences.
Geomorphology
Hydrology
Glaciology
Biogeography
Oceanography
Environmental
Geography
-branch of
geography that
analyzes the
spatial aspects of
interactions
between humans
and the natural
world

13. ENVIRONMENTAL ASSESSMENT
- is the assessment of
the environmental
consequences
(positive or negative)
of a plan, policy,
program, or actual
projects prior to the
decision to move
forward with the
proposed action.

14. - The purpose of the
assessment is to ensure
that decision makers
consider the
environmental impacts
when deciding whether
or not to proceed with a
project.
