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.
